Answer 1

can you post your code. Ideally it should !!!

Answer 2

If you postback your form when a row selected, you can set your currentrow's validator controls' ValidationGroup to an active text, and all other validation controls at other rows should have ValidationGroup inactive.

And also set your submit button's ValidationGroup to active text that causes validation.

This will allow your submit button to validate only validators with the active ValidationGroup.
