Catching a RequiredFiled Validator event in PageLoad or some other event?

[Lars Netzel]

Hi!

If I use a RequiredField Validator to make sure a TextBox is filled by a
user and the user DOESN'T it triggers and shows the errortext of that
control.

I want more to happen on the page when that happens and is there an Event or
something I can check that it has been triggered?

Regards

I would guess your would need to create a Custom_Validator and not specify
the control to validate (that way it will run even when your TextBox is
empty).

Inside your Custom_Validator check to see if the TextBox was empty and act
on it.

I believe you can use the IsValid property of the validator itself to
check this.

http://msdn.microsoft.com/library/e...WebControlsBaseValidatorClassIsValidTopic.asp

Note that validation happens AFTER the Page_Load event, so if you get
this property in the Page_Load event, it will always return True,
since the control has not yet been validated. If you must check
validity in the Page_Load event, you can manually call the
Page.Validate method (or just call the Validate method of the
validator you want to check on).

BUT, if he has client-side validation turned on he may never get back to the
server to run anything.
