Help with setting values when clicking on checkboxex of a combobox control

Its because the following condition

 If C1SDeactivation.Items(i).Selected Then

never evaluates to true.

I know but I don't know why because I did select the rows when I clicked on the checkboxes.

I may be wrong, but I think the checkbox property you are looking for is Checked not Selected ( you my need to cast the control to checkbox to access this)

I'm afraid checked is not a propery of the combobox, how do I cast the control tyo checkbox?
Thanks.

I think maybe this previous answer might help:

Hi Unfortunately,

I still can't figure out why the code I initially posted doesn't work now, it thought worked a few weeks ago, can you please take a closer look at the syntax to see why
 "If C1SDeactivation.Items(i).Selected then" is not executing even when I select the rows.

I think the problem might be because the ID of my checkbox is SDeactivation as shown below:

  <ItemsTemplate>
                            <asp:CheckBox ID="SDeactivation" runat="server" onChange="setColor(); " />
                             <%# DataBinder.Eval(Container.DataItem, "SDeactivation")%>
                         </ItemsTemplate>:

and my code is looking for the control with ID SDeactivation for the combobox. How do I ensure It is looking for data checked from the checkbox?

Code:


 Protected Sub Button131_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button131.Click

        Dim str1 As String = Nothing
        xx = 0
        yy = 0
        zz = 0
        ww = 0
        Dim ctrlA As Control = MultiView1.FindControl("C1SDeactivation")
        For i = 0 To C1SDeactivation.Items.Count - 1
            If C1SDeactivation.Items(i).Selected Then
                MsgBox("Test") *****Does not execute
                If i = 0 Then
                    xx = 1
                End If
                If i = 1 Then
                    yy = 1
                End If
                If i = 2 Then
                    zz = 1
                End If
                If i = 3 Then
                    ww = 1
                End If
            End If
            MsgBox(i)
        Next
        MsgBox(xx)
        MsgBox(yy)
        MsgBox(zz)
        MsgBox(ww)
End Sub

Control:

<cc1:C1ComboBox ID="C1SDeactivation" runat="server"
                         OpenDropDownOnLoad="True"
                         SelectionMode="Multiple" Width="180px"    
                         onselectedindexchanged="C1SDeactivationA_SelectedIndexChanged"
                         OnClientSelectedIndexChanged ="C1SDeactivationA_OnClientSelectedIndexChanged"
                         AccessKey="" ToolTip="" HideDropDownListOnBlur="False"
                         DropDownPositioningMode="BottomCenter" DropDownHeight="100"
                         Text="Select (Multiple Allowed)" ShowTrigger="False" IsEditable="False">
                          <ItemsTemplate>
                            <asp:CheckBox ID="SDeactivation" runat="server" onChange="setColor(); " />
                             <%# DataBinder.Eval(Container.DataItem, "SDeactivation")%>
                         </ItemsTemplate>
                     </cc1:C1ComboBox>


Thanks,

Have you stepped through the code? You have

Dim ctrlA As Control = MultiView1.FindControl("C1SDeactivation")
        For i = 0 To C1SDeactivation.Items.Count - 1
            If C1SDeactivation.Items(i).Selected Then

you are finding ctrlA but using name of the control

Try

Dim ctrlA As C1Combobox = MultiView1.FindControl("C1SDeactivation")
        For i = 0 To C1SDeactivation.Items.Count - 1
            If C1SDeactivation.Items(i).Selected Then

Hello,

I tried it but  "If C1SDeactivation.Items(i).Selected Then" still doesn't execute when I select the rows. Not certtain why use ctrlA since it is not used anywhere in the code, could that be the problem?

I'm afraid both approaches did not work, looking at an old project where it worked before but still can't figure it out will keep trying a get back to you. Thanks.
