Asp.net Response.Redirect
<p>I am using response.redirect after iam deleting a particular user to have grid populated with latest values.. but it giving me error
lblError.Text=Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.</p>

<p>because of this error iam not getting confirmation of deletion any help will be appreciated</p>

<p>code:-
  if (chk.Checked == true)
                        {</p>
