validation control headache

[NuB]

The validation controls are giving me a headache. here is what i'm trying to
do and so far what I've tried has not worked.

I need to hide my grid if the page is not valid
how can i accomplish that?

I have one validation control that gives an error if there is no data
returned, so if the page is not valid on another search i need that to go
away. How can i hide and show controls and labels bases on the page.isvalid

has anyone done this before

[NuB]

would that go in the page load or my button click method?

is there anyway to really get the grid.visible = false with using the
validationsumma ry controls, required field control, etc?

yes i know, I didn't create this app, I just started working on it and
they
have several validators for required fields, make sure they are the
correct length, and that some are numeric.
so i need to keep the current flow and existing code and just work with
that is already there.

so i'll research it some more

I think there should be a way to execute validation code on server
side. So whenever you post your server side validation executed and
based on the result of validation you can show hide your grid.

Correct me if I am wrong.
