The reason may be that tv.NamingContainer is null.
Put a break point on the line

C#

Panel pnl1 = (Panel)dataListItem.FindControl("pnlComments");

run the program and when the execution stops at the break point, check whether tv.NamingContainer is null. If so take check that code to get non null value.
