Can't find column

[Dennis]

I have a RadGrid in a page, and the header text for the columns is set dynamically in the PreRender event so that localization can occur.

I added three new columns to the grid, and for some reasion when I try to find these columns by their UniqueName, an exception is thrown.  If I comment out the call to the three new columns, the problem goes away. If I add any one of the three new columns back, the problem returns.  The problem occurs with the columns "OrderDate", "OrderNo", "PONumber"

Hello Dennis,

Try the following code snippet. Hope this helps you.

C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)

{
   RadGrid1.MasterTableView.GetColumn("ColumnUniqueName").HeaderText = "header";
   RadGrid1.Rebind();
}
 


Thanks,
Princy.
