title: GridView HeaderRow.TableSection error
body: <p>I have a bad error when setting GridViews HeaderRow.TableSection to TableRowSection.TableHeader: The table  must contain row sections in order of header, body, then footer. 
  Please, note, that I do it in grids DataBound event handler and I do NOT use paging. How can it be?</p>
  
  <p>Thank you,</p>
