You're not showing input string here, only showing output. It need exception dump and the code showing lines where exception was thrown.

Solution 1

Check the inputs you are converting. May be the value you are converting in e.Row.Cells[3].Text is not an integer value.
using int.TryParse doesn't raise any error though non integer value is passed.
