Search Navigation item on Quick Access Toolbar
0 Ivn P. 3 months agoHi,
I'm trying to add a new action on the Quick Access Toolbar. It
will be a textbox to search inside my Navigation control items. I
attach a sample of what I'mtrying to do.
Does XAF have a simple way to accomplish this task?, Do you
think my proposal is possible?
Thank you in advance.

Hello Ivn,Yes, it is possible to implement such a control.You
can create a WindowController, add ParametrizedAction and set the
QuickAccess property to true. As a result, the Action will be added
to the QuickAccess Toolbar.After that, you can use the How to:
Customize Controls Associated with an Action approach to customize
the Action's control or the How to create a customaction type with
a custom control (BarCheckItem), associated with it approach to
create a custom Action to display a drop-down control. For example,
youcan use RepositoryItemLookUpEdit to display a drop-down
control.You can use approaches described in the How to show a
window ( View ) representing data in XAF article to show View via
code.Please let me know if you need further assistance.
