RadGrid loop column and hide

[kenneth]

Is it possible to loop thru all the columns in a grid and get all the column names, and allocate those columns with empty header name, and hide from grid.

Hello,

protected void RadGrid1_PreRender(object sender, System.EventArgs e)
   {
       foreach (GridColumn column in RadGrid1.Columns)
       {
           if (string.IsNullOrEmpty(column.HeaderText))
           {
               column.Visible = false;
           }
       }
       RadGrid1.Rebind();
   }

Thanks,

But if rebind, all my selected for checkboxes will be reset back to null. I need to keep those selected check as well.~
