[Solved] Hide expand/collapse - no record

[Paul]

Hi Community,
    Need help with the hide expand/collapse (buttontype="ImageButton").   I have look at the documentation page http://www.telerik.com/help/aspnet-ajax/grid-hide-expand-collapse-images-when-no-records.html, but it hide everything.  Because the nestedView.Items.Count always equal to zero (Not sure if I'm doing it right).

I have an attachment column if they have an attachment it show the detail (detail table) about the attachment, when they don't have an attachment I want to hide the button or disable it.

Any help would be greatly appreciated it.

See attach image.

Problem Solved:
   Added the ExpandCollapseColumn-UniqueName="colExpandCollapse" into the mastertaveview.  In the ItemDataBound for the grid (.cs) added.

ImageButton imgbtnExpander = (ImageButton)item["colExpandCollapse"].Controls[0];
imgbtnExpander.Visible = bool.Parse(((DataRowView)e.Item.DataItem)["MyDataColumn"].ToString());
