error indicates To do 

  linkbutton _singleClickButton = (LinkButton E.RO.KEL [0]. [0];

Either you have any cellular There are rows without, or you have cells with less than three control.

To prevent the code from crashing, just check that you have enough items: 

  if (e.O.Cell.Count> gt; 0) {Table cell cell = E.RO.kel [0]; if (cell control calculation & gt; 2) {linkbutton_singleClickButton = (linkbutton) Cell Control [2]; String _jsSingle = ClientScript.GetPostBackClientHyperLink (_singleClickButton, "$ Select + e.Row.RowIndex); E. Rau Style ["cursor"] = "hand"; }}
