Aashish,
It could be that txtReason doesn't have a text attribute because it is not a textbox.
Why don't you try txtReason.selecteditem or one of the other dropdownlist variations.

change the line

Code:

viewState("reason") = s.txtReason

to

Code:

viewState("reason") = s.selecteditem.value

and see what happens.
Then go take a nap.
Really.

Try this:

Code:

viewState("reason") = s.selecteditem.value
