I've doubt on this statement here. foreach (GridViewRow gvr2 in GridView2.Rows ) { ((TextBox)gvr2.Cells[3].FindControl(txtAnswers)).Text = answerText; } Check the value of GridView2.Row see if its having any row? And if its 0 then you have to create some rows in the Gvr2 first. To add rows into grid programmetically then you should follow this article  New Rows in GridView . Hope this helped you.
