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

Hello,

When I click on several checkboxes to set a variables xx,yy,zz,ww to 1 for rows checked my code below (Msgbox ("Test") never executes, any ideas what is causing this problem?

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,

Victor

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.

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?

Yes that is the problem. I should have updated the rest of the code. So either

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

pr

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

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.
