i had the same problem once in one of my projects... i donno if its a bug or something...

to tackle this u can manually check what all values have been checked, and then insert these values as strings into the database

hi,

Loop through the CheckBoxList, get the value of each checkbox which is 'checked' and seperate each item with a comma. here is the

sample code for you

string interests = string.Empty;

foreach (ListItem item in this.CheckBoxList1.Items)

if (item.Selected) interests += item + ",";

SqlCommand cmd = new SqlCommand("Insert into Demo values('" + interests + "')", cn); //Write Your Query to insert into database table cn.Open();

int iCount = cmd.ExecuteNonQuery(); cn.Close();

I would like to provide you the retrieve code also

void LoadCheckList() {

string intersts = "";

SqlCommand cmd = new SqlCommand("Select Interests from Demo", cn); // Write your Query i have taken as sample SqlDataReader dr; cn.Open(); dr = cmd.ExecuteReader();

if (dr.Read()) { intersts = dr["Interests"].ToString(); }

cn.Close(); string[] arr = intersts.Split(',');

foreach (ListItem item in this.CheckBoxList1.Items) {

foreach (string s in arr) {

if (item.Text== s) { item.Selected = true; } } } }

Hope this will help you

I have done this for ListBox , similarly you can do with CheckBox list

protected void btnSave_Click(object sender, EventArgs e)

{

StringCollection sc = new StringCollection();

foreach (ListItem item in lstItems.Items)// iterate through listitems

{

if (item.Selected) // if item is selected

{

sc.Add(item.Text);

}

}

InsertRecords(sc);

}

// In the above I am adding all the selected items to string collection tehn passign it to a function InsertRecords

protected void InsertRecords(StringCollection sc)

{

StringBuilder sb = new StringBuilder(string.Empty);

foreach (string item in sc)

{

const string sqlStatement = "Insert into employees values";

sb.AppendFormat("{0}('{1}')", sqlStatement, item);

}

try

{

con.Open();

SqlCommand cmd = new SqlCommand(sb.ToString(), con);

cmd.CommandType = CommandType.Text;

cmd.ExecuteNonQuery();

Page.ClientScript.RegisterClientScriptBlock(typeof(Page), "Script", "alert('Saved Records Successfully');",true);

foreach (ListItem item in lstItems.Items)

{

if (item.Selected)

{

item.Selected = false;

}

}

}

catch (Exception ex)

{

string msg = "Insert Error";

msg += ex.Message;

throw new Exception(msg);

}

finally

{

con.Close();

}

}

That's it
