Check a ClientSelectColumn in codebehind

[Bruce]

 

My aspx page has

    <telerik:GridClientSelectColumn Reorderable="False"  UniqueName="ClientSelectColumn">
              <HeaderStyle Width="20px"></HeaderStyle>
    </telerik:GridClientSelectColumn>
 

In my code behind, I want to initialy check some rows.  How do I code this?

The following code does not produce an error, but nothing is checed when the page is displayed
(I've tried this the following events: ItemDataBound, ItemCommand, and PreRender

    Dim chkClientSelectColumn As CheckBox = DirectCast(item.FindControl("ClientSelectColumnSelectCheckBox"), CheckBox)
    chkClientSelectColumn.Checked = True

Hi Bruce,

Try the following code snippets for selecting the rows fom code behind based on a condition.

VB:

Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs)
    If TypeOf e.Item Is GridDataItem Then
        Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)
        If item("CategoryID").Text = "1" Then
            ' Check for the condition
            item.Selected = True
        End If
    End If
End Sub

Thanks,
Shinu.

I'm not trying to see which rows are selected, I'm trying to set a row to being selected

Hello Bruce,

I believe that the code snippet, provided by Shinu will be working as expected. You can also select an item of your choice  (together with the checkbox) as shown below:

Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    RadGrid1.MasterTableView.Items(2).Selected = True
End Sub
