Use the debugger. Debug the program then when you get the exception look at what line of code that got the error. Look to see what is null.

Remember to use VB.net If e.Row.RowType = DataControlRowType.DataRow Then End If c# if (e.Row.RowType == DataControlRowType.DataRow) { }

Send the code and specially the data. Several things come into my mind that can cause this exception. I want to be specific.
