And is that because the exception you originally mentioned is still being thrown? Or is that field just not appearing?
if i m trying to print that value, it showing me exception.
but i m just adding that value to textBox, it not showing me exception, but also no data appear in that field.
In the latter case it's probably because you're writing the data to a component which isn't in the GUI:
what do you mean by this?
you mean that i have not declared
txtFeeDue, but i have declared it in my code, i have not posted my whole code..
