[Solved] Hide columns after data-binding

I have a simple RadGrid:

<telerik:RadGrid ID="rgHeaderKey" runat="server">

<HeaderStyle Font-Bold="true" />

<MasterTableView HeaderStyle-HorizontalAlign="Center" HeaderStyle-Font-Bold="true" />

</telerik:RadGrid>

The columns and rows are bound to a table in a database; yet some of the columns do not contain any data (that is, all the entries in that column are NULL). I need to hide those columns that do not contain any data after the grid has been filled. I tried the following handler for the OnDataBound event:

protected void GridHeaderKeyDataBound(object sender, EventArgs e)

{

// after data-binding, hide any columns that have no entries

for(int i = 0; i < rgHeaderKey.Columns.Count; i++)

{

// check the entry in the first row

GridColumn col = rgHeaderKey.Columns[i];

if (String.IsNullOrEmpty(rgHeaderKey.Items[0][col].Text)) col.Display = false;

}

This fails, however, because rgHeaderKey.Columns.Count is always 0, even after the data have been bound (which I find a bit strange). I realise this might be because the columns are automatically generated: however, I need it this way because I do not know the names of the columns in advance.

Any help would be very much appreciated.
