I have a Radgrid with auto generated columns = "True" and I would like to change the header text programmatically at the Detail table levels when the radgrid loads at page load.  How would I accomplish this?  I figured simply utilizing the code shown below would work, but it doesn't do anything.  The page just loads with no errors, and the text does not change on the header.  However, when I change the text programmatically in the root level of the radgrid it works, but does not work at the detail levels.  Please Help!

'''I tried this code in the PreRender and ItemDataBound Events.  But it does not work. Text does not change.... 

Radgrid_CRGList.MasterTableView.DetailTables(1).DetailTables(0).GetColumn("UniqueName").HeaderText = "Custom Header Text"

Hi Aret,

You can try the following code snippet in the PreRender event to set HeaderText.

VB:
Protected Sub RadGrid1_PreRender(sender As Object, e As EventArgs)
    'Setting HeaderText
        '1st level of Hierarchy
    RadGrid1.MasterTableView.DetailTables(0).GetColumn("StateID").HeaderText = "Custom Header Text"
         
        '2nd level of Hierarchy   
    RadGrid1.MasterTableView.DetailTables(0).DetailTables(0).GetColumn("DistrictID").HeaderText = "Custom Header Text" 
End Sub

Thanks,
Princy

Hi Kapil, 

Which version of the controls are you using?

You can attach a handler to the Grid's PreRender event like follows:

ASPX:

        <telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" Width="800px" OnPreRender="RadGrid1_PreRender">
            ...
        </telerik:RadGrid>
