How do you make gridview controls disappear?

[COHENMARVIN]

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
Marvin

It seems you have a hard coupled system here.. I don't think -999 will work

Anyway try to wrap the gridview with a div tag (run at server) and hide the
div, when post back, that should work for sure

If you are using declarative databinding with DataSourceID, you need to run
select on the datasource to refresh the grid.
