ASP.NET MVC edit collection of itemsA very common scenario for line of business apps is to edit a

collection of items. Often this

isn’t a bit collection, just a

variable number of rows with a

few columns to edit per row.

The MVC scaffolding supports this scenario by making it easy to

create a set of pages – display the list, create a new item, edit

an existing item, confirm removal of an item. And this

scaffolding is quite useful, especially for scenarios where each

row of data has a lot of properties to edit.

Where it isn’t so useful is in another common case, where each

row of data has a small number of properties to edit (and where

there are a relatively small number of rows). In this case most

users would prefer to just edit all the values on a single screen,

not having to navigate to the create/edit/delete pages for each

row, as that is quite awkward.

What I’ve found is that there are some (ok, lots) of blog posts

and code snippets showing ways to solve this problem. Much of

this content dates back many years, often to MVC 2, and shows

what (in my view) are some pretty hacky solutions involving

client-side JavaScript that manually creates html strings that

replicate (often outdated) html comparable to that generated by

MVC in Razor. Other solutions use WebGrid, a seemingly little-

used feature of MVC that also needs some (less hacky)

JavaScript to support editing.

For my purposes, I wanted something simpler, more direct. I

don’t mind some postbacks – you’d get those with the standard

MVC scaffolding – I just want the user to feel like they are just

editing the list of items without a lot of page navigation.Something like this:

I also don’t mind using Session in this case, because I’m

building something that will, at most, be used by 0.3% of our

employee base, which is currently around 600 people. If we

grow enough that scaling is an issue we’ll obviously have

To that end I created a new ASP.NET MVC 5 project in Visual

Studio 2015 and added the files in this gist that contain the

implementation.

The ProjectListController serves up the initial page, and accepts

POST operations from the browser.

The Index method displays the page with the collection data. If

Session is empty the data is loaded from the database,

otherwise the cached Session data is used to populate the page.

Typically this means that the first time the user arrives at the

page they’ll get fresh data from the database, and on postback

operations the data will come from Session. Basically I’m using

Session as an in-memory scratch location for the data until all

edits are complete and the user clicks the button to save the

data.

The POST method works differently depending on the button

clicked by the user, handling add, remove, cancel, and submit

operations. The operation is indicated by the value of the

button, which flows into the controller through a method

parameter. In every case the POST method has the full contents

of the collection from the UI that flows from the browser into

the method.

The add operation adds a new/empty item to the collection,

updates the state in Session and allows the page to be

redisplayed. This means the newly added item appears to the

user, but hasn’t been saved to the database.

The remove operation removes the selected item or items from

the collection, updates the state in Session and allows the pageto be redisplayed. This means the removed items are no longer

displayed, but haven’t been removed from the database.

The cancel/refresh operation clears Session and redisplays the

page, causing the page to display fresh data from the database.

The submit operation saves the data into the database, then

clears Session to ensure that when the page is redisplayed that

the user gets fresh data from the database (including the newly

saved changes).

The Index.cshtml view implements the page, relying on the

Person.cshtml view to display each row of data from the

collection. The Index view has all the buttons the user can click

to trigger the postback operations to the controller as I just

described.

The Person.cshtml view creates the edit controls for the

properties the user should view/edit for each row.

The Person.cs file implements the model – really the viewmodel .

Notice that it has a Removed property which is very UI specific,

so this clearly isn’t the actual model you’d ever get/save in a

database.

The controller has TODO comments indicating where code

should go to invoke the data access layer to retrieve and update

the database based on the in-memory collection of Person

objects.

CSLA .NET Version 4.6.400

releasedThis release of CSLA .NET isfocused primarily on enhancing

the existing Xamarin support.

There is now a Csla.dll targeting

PCL Profile111, which is the

current profile for Xamarin.Forms

projects and .NET Core.

There is also now a CSLA-Xamarin NuGet package that includes

a Csla.Xaml.dll with support for Xamarin.Forms. This includes

the same viewmodel base classes as the other XAML platforms,

and an implementation of the PropertyInfo control tailored for use

in Xamarin.Forms.

@JasonBock added even more analyzers for Visual Studio 2015

to help developers avoid common coding mistakes when

building CSLA .NET business classes.

We now have support for the prerelease of Entity Framework 7.

The pt and pt-BR resources for Csla.dll have been updated.

Other languages need updates as well - please contribute

if you are a native speaker!

CSLA PropertyInfo control forXamarin FormsThere is now a

Csla.Xaml.PropertyInfo control for

Xamarin Forms as well as

WPF/UWP, so you can use the

same technique to access all

metastate about each property

from your XAML.

This means that (now on Xamarin

too) you can bind to the property

value, as well as CanRead, CanWrite, IsValid, IsBusy, and

various other metastate values.

Using this capability your XAML UI can provide the user with

immediate and rich visual cues as to whether the user is allowed

to read or write the property value, and whether the current

property value is valid (and if not, why), as well as whether the

property has any outstanding async business rules currently

executing.

mono DisplayAttribute problemreproThe CSLA PCL that supports Xamarin includes an

implementation of System.ComponentModel.DataAnnotations, and that

includes numerous types, one of which is DisplayAttribute.

The PCL uses type forwarding so at runtime the platform'sDataAnnotations implementation is used (if available), and the

CSLA implementation is only used at runtime for platforms

where there's not already an implementation (WinRT Phone is

the only remaining platform afaik).

There is a problem with Xamarin however, where all types seem

to forward and work fine except for DisplayAttribute. The problem

in this case is that at runtime it seems that mono is unable tolocate the correct ctor for the type:

"System.MissingMethodException: Method 'DisplayAttribute..ctor' not foun

pe type, System.String name) [0x00011] in :0 \n at Cs

This exception occurs when the consume app attempts to access

the DisplayAttribute associated with a property to retrieve values

from the attribute. It appears that mono is unable to create an

instance of the attribute object because it can't find the ctor.

The DisplayAttribute class has only a default ctor, but is typically

initialized using named parameters, such as:

[Display(Name = "foo")]

I don't know what kind of ctor mono is looking for when it fails,

but it obviously isn't finding the default ctor and then setting the

property value, which is what would be the expected behavior.

I’m tracking this issue in the CSLA GitHub repo:

https://github.com/MarimerLLC/csla/issues/579

Steps to reproduce issue

The CSLA ProjectTracker reference app in my fork includes a

repro of this issue. To see the issue, do the following:

1. Clone my fork of CSLA from

https://github.com/rockfordlhotka/csla.git

2. Checkout the 505-xamarin branch:https://github.com/rockfordlhotka/csla/tree/505-xamarin

3. Open the \Samples\ProjectTracker\ProjectTracker.sln

solution

4. Build the solution – it’ll pull down the CSLA .NET framework

from NuGet

5. Set a breakpoint in the

XamarinFormsUi.ViewModels.ProjectList class as shown

here

6. Set the startup app to ProjectTracker.Ui.Xamarin.Droid

7. Run the app in debug mode (on an emulator or device)

8. On the first screen click the All Projects button

That’ll attempt to load the ProjectList page and ProjectList

viewmodel. At this point the exception will occur and you’ll end

up on the breakpoint because of the failure to create an

instance of ProjectInfo, but that fails because mono can’t create

an instance of DisplayAttribute (used on some properties in the

ProjectInfo class).

ctor bug in Xamarin/mono?I might have found a bug in mono, but want to see if anyone

thinks I'm missing something.

The CSLA .NET framework has long included an implementation

of the System.ComponentModel.DataAnnotations namespace for

platforms where Microsoft/Xamarin didn’t provide that

functionality. These days I think that is only Windows Phone 8.1,

but that includes PCL Profile111 (which is what Xamarin

currently targets as well).

Of course the CSLA implementation includes the

DisplayAttribute class, which is used to decorate properties in

consuming classes like this:

[Display(Name = "blah")]

That "blah" value is a human readable name/label for a

property.

Because mono actually provides a

System.ComponentModel.DataAnnotations implementation, my

PCL uses type forwarding so at runtime the PCL implementation

is ignored in favor of the platform-specific implementation

provided by mono. For example:

[assembly: System.Runtime.CompilerServices.TypeForwardedTo(typeof(System

This works great on all platforms - except Xamarin Android/iOS

where mono throws an exception because it can't find a

matching constructor.

The thing is that the DisplayAttribute class has only the default

constructor. The syntax being used to set the Name property of

the attribute is supposed to use the default ctor, and then the

Name property is explicitly set. This is a relatively old feature of

C# - but I kind of suspect mono has a bug around this area, as

it seems to be looking for a ctor that accepts a parameter when

it should use the default ctor.

Thoughts from a Windows 10 userThere’s a lot of speculation at

the moment, mostly I think from

the tech press, that there’s no

future for Windows 10 Mobile

(aka Windows Phone). To the

point that Terry Myerson

apparently released a statement to clarify that Microsoft is

committed to mobile for many years.

Over the past couple years I’ve been increasingly critical of

Microsoft’s mobile strategy as well – it is hard not to be when

the platform has such low market share, there’s been a lack of

flagship devices released, and there’s still a major issue withapps (that don’t exist or that are quite poor compared to

iPhone/Android versions).

So at the beginning of this year I “threw in the towel” and

switched to the iPhone. This was after talking to a lot of people

in person and via twitter about whether to go iPhone or Android.

The overwhelming advice was that if you live in the US you

should go iPhone, so I did exactly that.

After a couple weeks with the iPhone I wrote a comparison

between Windows 10 Mobile and the iPhone – from my

perspective. I’m selfish – I’m looking for a good answer for me,

so my blog post was about me and my personal experience.

After a couple more months I realized that this is a real tradeoff,

because Windows 10 Mobile the operating system is more

consistent and polished than iOS, but the apps on the iPhoneare almost universally superior.

At that point I thought I’d try Android. This was right after

Microsoft Build 2016, where it seemed like there was a lot of

love for Android, and where I encountered a whole lot of my

peers who were incredulous that I had an iPhone instead of an

Android (where they were last fall when I was soliciting input I

have no idea – I begin to suspect that people only advocate for

their platform when you have “the other platform” in your

pocket). Basically, some of the iOS frustrations and

inconsistencies were bugging me enough I wanted to look

elsewhere.

I didn’t even last a couple weeks on Android though. I bought aOnePlus 2 – a high-end device with very generic Android. It

turns out that generic Android pretty much sucks – much like

generic Linux. You need to spend (in my experience) hours and

hours and hours researching and trying different launchers, lock

screen apps, email apps, calendar apps, contact apps, etc. Just

to get basic functionality that works out of the box in the iPhone

and Windows 10. O.M.G. I don’t understand how people can

waste that much time just getting the basics to work on theirphones!?!

Now I’m back to Windows 10 with a Lumia 950xl. And I’m

happy.

I keep hearing how Windows “lacks polish”. Clearly this

statement is being made by people who have not actually used

Windows 10, iOS, and Android back to back like I just did. Insome ways iOS might have more polish, but it is far, far less

consistent than Windows, so I give the OS polish nod to

Windows 10. Android isn’t even in the running – it has no polish

or consistency – though maybe with another many hours of

research and testing I could have found a launcher that I liked?

That’s not how I want to spend my life.

I also keep hearing about the Windows “app gap”. That is

obviously a real problem. It is absolutely the case that the

iPhone has a lot more apps, and almost all the apps are

superior. It is also the case that the Android apps are plentiful,

but they generally look like crap compared to their iOS

counterparts. But I’ll give it to Android that, though its apps are

inconsistent and often cartoonish, they are full featured, unlike

Windows apps.

One other note on apps: Android is clearly designed to work well

if you are a Google user (mail/calendar/contacts) and it is pretty

half-baked for people not on Google. I can’t say I support the

EU going after Google any more than I did when they went after

Microsoft so long ago – I think that’s just dumb – but at the

same time, I understand their consistent view here, because

Google is using Android to drive usage and lock-in around theircloud service offerings, not unlike what Microsoft did 20 years

ago with Windows.

Finally, I keep hearing how Windows phone hardware is inferior.

I even heard that from someone at Microsoft. I’m skeptical. It is

true that the iPhone 6s is a really nice device, and I love the

fingerprint unlock feature. Android device quality varies a lot,

but the OnePlus 2 is pretty nice (if a bit heavy) and has afingerprint reader (if you can find a lock screen app that

supports it). The Lumia 950 is nicer and lighter than the Android

devices I’ve seen and used (including the Samsung ones). But

I’ll grant that it isn’t as nice as the iPhone. At the end of the day

though, I think all three platforms have hardware that are

basically in the same ballpark: reasonably stylish, light, fast,

with decent battery life, and great cameras. If it was just down

to hardware my ranking would be iPhone 6s, Lumia 950,Samsung Android, other Android – in that order.

At this point though I’ll remind you that I’m selfish here – I’m

after a solution for me.

That means it comes down to iPhone vs Windows 10 Mobile –

the Android OS is too unpolished, clumsy, and inefficient; and

its apps are too ugly, inconsistent, and cartoonish. It is clearlythe cheapest platform, and you get what you pay for. I’m willing

to pay to get a more productive experience.

And at the end of the day there are only 3 apps that don’t exist

or don’t work on Windows that I actually need: Swarm, Waze,

and the Parrott Bebop app for my drone.

My bank does have an app on iPhone/Android, but it sucks

http://www.lhotka.net/weblog/ct.ashx?id=be6d4e13-99c0-44be-ac8b-4c9f1648192a&url=http%3a%2f%2fwww.newser.com%2fstory%2f205457%2feurope-is-going-after-google.html


13/26



and so not having it isn’t really a loss. To solve my bank app

issue I need to switch to a better bank, not a different phone.

I weighed the value of those 3 apps against Windows 10’s more

polished and consistent OS experience; and I considered that

Siri is like Cortana’s dullard older sister (yes, Siri is really an

idiot compared to Cortana, and Cortana on the iPhone iscrippled compared to Windows or Android).

Ultimately I’ve decided that I’d rather go with the best OS on a

regular basis. In my case I’m fortunate enough that I can carry

a second phone (sans SIM) so I can still fly my drone – it just

needs the app and wifi after all. That also gets me Waze and

Swarm, because they also work over wifi, and my Lumia works

great as a wifi hotspot when I’m out and about.

At the end of the day, until Foursquare, Google, and Parrot (and

my bank) get their heads out of their @$$’s I am working

around them via a two phone solution.

But most importantly , I’m happy using Windows 10 and Cortana

for my 99% use case of

email/calendar/phone/text/messaging/Office/etc.

And fwiw, I think the continued rapid adoption of Windows 10

itself (on my Surface and Desktop for example) will drive more

and more companies to create UWP apps – perhaps not initially

for the phone, but at least for the 300 million (and climbing)

people running Windows 10. The thing is, once your app runs in

UWP, getting to the phone is a pretty small step – and one

companies would be foolish not to do for such little effort.

Windows to iPhone to AndroidEarlier this year I embarked on an “adventure”. I was frustrated

with the lack of apps on Windows Phone (Windows 10) and I

keep hearing how magical the iPhone is for people. After a

couple weeks with the iPhone I wrote a comparison blog post:

Windows Phone vs iPhone comparison

More recently I wrote about my ongoing frustrating with the

iPhone, justifying why I was going to try an Android device:

iPhone frustration

I’m trying to give each platform a fair try, but after a few short

days with Android (I have a OnePlus 2 – so very “vanilla”

Android) I’m already finding that of the three operating systemsAndroid is the worst. It is kind of like desktop Linux – cobbled

together by a lot of people who don’t share a common vision, so

everything sort of works, but nothing feels consistent and most

things don’t seem professional or polished. Kind of the diametric

opposite of the iPhone.

I’ve always thought that you get what you pay for, and I think

Android reinforces that worldview. It is cheap, the devices arecheap, the apps are free or cheap. And they all feel cheap when

compared to Windows 10 or iOS. But if your phone isn’t a

budgetary priority in your life, yet you need a smartphone, then

Android is probably the right choice – which explains why it is

the most popular OS globally. Clearly the majority of the world’s

population either can’t afford a professional phone/experience

(which is largely true of course), or they don’t value their own

time as much as money, so they are willing to invest that timedealing with Android instead of spending the extra money up

front to get an iPhone or Windows Phone.

Notice that I’m still putting Windows Phone in this discussion,

even though it has a low US market share, and only a slightly

better global market share. In my experience with the three

platforms thus far, my conclusion is that the operating systems

http://www.lhotka.net/weblog/ct.ashx?id=c4a3546b-dfa7-4109-b3d0-b8cfb7594223&url=http%3a%2f%2fwww.lhotka.net%2fweblog%2fiPhoneFrustration.aspxhttp://www.lhotka.net/weblog/ct.ashx?id=c4a3546b-dfa7-4109-b3d0-b8cfb7594223&url=http%3a%2f%2fwww.lhotka.net%2fweblog%2fct.ashx%3fid%3d7ee4c54f-f4e9-44f5-9e63-981f5a4dda0c%26url%3dhttp%253a%252f%252fwww.lhotka.net%252fweblog%252fMyWindowsPhoneVsIPhoneComparison.aspxhttp://www.lhotka.net/weblog/WindowsToIPhoneToAndroid.aspx

rank like this:

1. Windows 10

2. iOS

3. Android

The physical devices I’ve been using rank like this:

1. iPhone 6s

2. Lumia 950xl

3. OnePlus 2

The availability and quality of apps rank like this:

1. iOS

2. Android

3. Windows 10

If you assign numeric scores to each category, you end up with

the following overall ratings:

iPhone (8)

Windows 10 (6)

Android (4)

So at least in my opinion – based on how I use my phone and

what I expect out of it – I probably should keep using my

iPhone, and keep grumbling about how dumb Siri is compared

to Cortana. Or I should go back to Windows 10 and deal with

the sad reality that it doesn’t have workable Waze, Swarm, or

banking apps.

A lot of people I know do carry two phones (personal and work).

I’m sort of considering carrying 2 devices – a Windows phone

with a SIM as my primary (so I have Cortana and all the other

stuff I love about Win10) and an iPhone without a SIM to run

the apps that don’t exist on Win10, because they all run over

WiFi. Just a little twist on the work/personal dual phone scenario

– but in my case I’ll have one phone that’s fun to use (Win10),


16/26



and one phone that runs apps that are fun to use (iPhone).

iPhone frustrationEarlier today I tweeted that I have

an Android phone on order,

because I’m frustrated with my

iPhone.

Not surprisingly that resulted in

people wondering why I’m

frustrated.

My iPhone experience started in

mid-January when I switched from

Windows 10 Mobile to iOS because I was frustrated by the lack

of apps on my Windows phone. A couple weeks later I wrote up

my Windows Phone vs iPhone comparison. After a couple more

months of using the iPhone I stand by what I wrote in that post

– Windows 10 is far superior to iOS, but the lack of apps on

Windows phones is crippling.

But there are some things that really bug me about the iPhone –

frustrations I face literally every day. Most notably:

No live tiles – man do I miss live tiles!Cortana on the iPhone is crippled, and Siri is an idiot

The “back navigation” concept on the iPhone is ridiculously

inconsistent and poorly implemented

The concept of sharing from one app to another is robust

on iOS, but is also ridiculously inconsistent and convoluted

So many things that are simple on Win10Mobile require a

lot more taps/swipes/effort on iOS

http://www.lhotka.net/weblog/ct.ashx?id=7ee4c54f-f4e9-44f5-9e63-981f5a4dda0c&url=http%3a%2f%2fwww.lhotka.net%2fweblog%2fMyWindowsPhoneVsIPhoneComparison.aspxhttp://www.lhotka.net/weblog/ct.ashx?id=7ee4c54f-f4e9-44f5-9e63-981f5a4dda0c&url=http%3a%2f%2fwww.lhotka.net%2fweblog%2fcontent%2fbinary%2fOpen-Live-Writer%2f8425ce6a3ed9_DC78%2fthO531UYN9_2.jpghttp://www.lhotka.net/weblog/iPhoneFrustration.aspxhttp://www.lhotka.net/weblog/default,date,2016-04-08.aspxhttp://www.lhotka.net/weblog/FormatPage.aspx?path=siteConfig/disclaimer.format.htmlhttp://www.lhotka.net/weblog/WindowsToIPhoneToAndroid.aspx

I know that Android won’t solve or address all these issues.

Maybe it won’t address any of them, I won’t know until I try it.

And I say that based on my experience switching to the iPhone;

everybody prioritizes different features and abilities differently,

so I find it virtually impossible to get at the “reality” of each OS

by talking to other people.

Here’s what I think I will find on Android:

No live tiles – still my number 1 issue with any other phone

OS

Cortana on Android is reputed to be much better than iOS;

almost as good as Windows; and the new Windows 10

Anniversary Edition mobile integration features work with

Android as well as Windows 10 Mobile (but not iOS)Android has a back button, so I am hopeful the “back

navigation” experience will be more consistent than iOS

(which is, frankly, a very low bar)

I don’t know what to expect about inter-app sharing, but I

suspect Android is no better than iOS (and let’s be honest,

this is also a weak spot for Windows phones)

I also don’t know that Android will be as optimized for

common tasks as Win10, but I can’t imagine it will be moreawkward than iOS

At the end of the day though, my three daily frustrations are

simple:

1. Live tiles (and the lack thereof)

2. Cortana

3. Consistent navigation patterns (especially the back

navigation concept)

Android seems to have a good chance of addressing two of the

three, so perhaps I’ll be happier day to day than I am with the

iPhone?

I guess time will tell. At least I’ll be able to know first-hand how

all three mobile operating systems work for me.
