Form still being submitted despite being invalid

[Guest]

I have a GridView control which contains a number of textbox controls. Each
textbox, has 2 validators assigned to it; a required field and a compare
validator (data type integer compare). These validators have their validation
group set the same.

If I enter an invalid value into a textbox, the CompareValidator's message
appears (*) when the textbox loses focus. However, if then submit the form,
it submits fine!!

A validation summary control should appear displaying a message telling the
user what the problem is.

I would post the form's source but it's a very complicated form and it would
be too big to post. Funnily enough, if I copy just the gridview control and
the validators, etc from the page and put them in a test page, the validation
works fine

Are there any common things to check?

You ought to set ValidationGroup for each TextBox control and for Button
WebControl too.

I've just figured it out. I'm appending another client-side onclick event to
the form's button and it appears to be affecting the validation.

Have you set the validation Display to none.

If so, you'll have to set:

if(Page.IsValid)
{

}

In your method you want to use these on.
That will prevent the page from displaying.

looks to me that script versions are different.
