Hi,

Since the object that you have used is null, you got the specified error.

Check the few object values,

(e.Row.FindControl("litPurata")
DataBinder.Eval(e.Row.DataItem, "KUIZ1")

check the "e" , e.Row value, findcontrol, dataitem values in the debug mode. similarly do the rest and let us know.

as a feedback, Always use "CODE" tags while posting your source code.

Thank you,

sory im new here.dont know how to paste the code.but now i know it.
this is my behind code:
