Hi all,

I've created an User control. It's an extension of a textbox wich has some extra properties so that validation becomes a lot faster.

The control wordks great if autopostback is on. When there's a value in the textbox, the (overridden) textchanged event fires and validation is performed.

Now I want to turn off autopostback. So I want my contol only validate if the submit button is pressed. I've tried Page.Validate(), but It seems only to trigger Validators. My control doesn't have to have validators, but just raises an error.

So, I think the question is: how do I trigger the overridden textchanged event of my custom control, preferably without writing code in de click event of the submit-button?

Odd.. shouldnt it trigger it iself since autopostback is turned off.. the
submit button should cause the textchanged event to trigger as long as u did
cause a change in the textbox...
