CheckBox template always evaluate to False even if checked in a DataGrid
hosted inside a TabStrip in ASP.NET


Hi,

I am trying to develop an ASP.NET application. I am using TabStrip
(which is part of IE WebControls).

Inside a tab I have a datagrid defined as follows:



<iewc:multipage id="MultiPage_Control" style="Z-INDEX: 103; LEFT: 452px;
POSITION: absolute; TOP: 297px" tabIndex="3" runat="server"
Height="160px" Width="458px" BorderColor="#C0C0FF" BorderStyle="Ridge"
SelectedIndex="3">
<IEWCAGEVIEW>Customers
<DIV id="Layer6" style="WIDTH: 250px; POSITION: relative; HEIGHT: 80px">
<asp:datagrid id="dgAssignedTo" style="Z-INDEX: 104; LEFT: 13px;
POSITION: absolute; TOP: 17px" runat="server" BorderColor="black"
BorderWidth="1" CellPadding="3" AutoGenerateColumns="False">
<HeaderStyle BackColor="#00AAAA"></HeaderStyle>
<Columns>
<asp:TemplateColumn>
<ItemTemplate>
<asp:CheckBox id=CheckBox1 runat="server" Checked='<%#
DataBinder.Eval(Container.DataItem, "Active") %>'>
</asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>
<asp:TemplateColumn HeaderText="Store Address">
<ItemTemplate>
<asp:Label ID="lblUsername" Text='<%#
DataBinder.Eval(Container.DataItem, "Username") %>' Runat="server" />
</ItemTemplate>
</asp:TemplateColumn>
<asp:TemplateColumn HeaderText="Store Address">
<ItemTemplate>
<asp:Label ID="lblName" Text='<%#
DataBinder.Eval(Container.DataItem, "Name") %>' Runat="server" />
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:datagrid>
</DIV></IEWCAGEVIEW>
<IEWCAGEVIEW></IEWCAGEVIEW>
<IEWCAGEVIEW></IEWCAGEVIEW>
<IEWCAGEVIEW></IEWCAGEVIEW>
<IEWCAGEVIEW></IEWCAGEVIEW>
</iewc:multipage></form>



which is basically a datagrid which has a checkbox (1st column) and 2
other columns
(employee usernames).


What i want is when the user checks a checkbox, I can save that to the
database.



Public Sub cmdSave_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles cmdSave.Click



Dim myDataGridItem As DataGridItem
Dim chkSelected As System.Web.UI.WebControls.CheckBox
Dim strUserName As String


conHelpdesk.Open()


For Each myDataGridItem In dgAssignedTo.Items

chkSelected = myDataGridItem.FindControl("CheckBox1")
' If chkSelected.Checked Then
strUserName =
CType(myDataGridItem.FindControl("lblUsername"), Label).Text
System.Diagnostics.Debug.WriteLine(strUserName)


strCriteria = "Update employee Set Active=@strActive " _
& " Where Username=@strUsername"

System.Diagnostics.Debug.WriteLine(strCriteria)
cmdSelect4 = New SqlCommand(strCriteria, conHelpdesk)
cmdSelect4.Parameters.Add("@strUsername", strUserName)
cmdSelect4.Parameters.Add("@strActive", SqlDbType.Bit).Value
= chkSelected.Checked
cmdSelect4.ExecuteNonQuery()

' End If
Next

conHelpdesk.Close()

End Sub



However even if the user checks the checkbox next to the employee column
'chkSelected'
always evaluates to false.

This same code when the datagrid is outside of the TabStrip executes
fine but inside the
TabStrip always evaluates to false.

I have checked MSDN KB but cannt find any errors.

Pls Help,
Rgs,
