I have a gridview control that is filled by the user adding rows to it
with a submit button.  Once he is totally through, I want to give him
a 'success' message and then empty the grid.  That should be easy,
because the grid is full of records that are from a database where the
select statement retrieves by using a compare parameter that is a
session variable.  In other words, something like this
Select * from MyTable Where FormID = @FormID
FormID is a session variable.
So simply setting the session variable to something impossible, like
-999, should clear the grids.  But it doesn't.  I tried doing a
gridview.databind statement after the -999, but that did not help
either.
Finally I tried making the gridviews invisible using their 'visible'
property - that also did not work!
Is there some bug here?  Is the page not refreshing?
Can I force a page refresh?
Thanks
