Conditional display: ItemDataBound vs PreRender

[Jay]

I'm new to the grid so please bear with me. I've got a GridTemplateColumn which I'm using to display an image.

<telerik:GridTemplateColumn HeaderText="Address" UniqueName="Address" ItemStyle-Width="20">
    <ItemTemplate>
        <a href='<%# Eval("Address") %>' title='<%# Eval("Address") %>'><img src="images/go.gif" border="0" width="33"></a>
    </ItemTemplate>
</telerik:GridTemplateColumn >

This shouldn't be visible if the data is empty, so in the ItemDataBound method, I did

Dim item As GridDataItem = CType(e.Item, GridDataItem)
If condition Then
    item("Address").Controls(0).Visible = False
End If

And this worked just fine under FireFox. But with IE8, it doesn't. Instead, I had to move this to the PreRender method where I had to iterate through the items with the same logic to get it to work. And this approach also works fine under FireFox too, so that's good.

But since I'm new to the grid, I'm wondering, is there a "correct" or recommended place to do this kind of logic? I initially went with the ItemDataBound because that's where similar approaches that I'd found (e.g. here ) had done it. But that obviously didn't work for me with IE8.

Hello Jay,

The RadGrid event sequence is as explained in this documentation.
Event sequence.
ItemDataBound event fires when controls are bound to radgrid. One better approach is to hide the column in prerender event as shown below.
C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
 RadGrid1.MasterTableView.GetColumn("Address").Visible = false;
}
