Difference between Validated and Validating
-
Dear Sirs, I can't figure out the difference between
Control.ValidatedandControl.Validating. I see the difference is that one's called, then the other's called. Here is the code I found inControl:if (this.NotifyValidating())
{
return true;
}
if (bulkValidation || NativeWindow.WndProcShouldBeDebuggable)
{
this.NotifyValidated();
}So it looks like
Validatingcan cancel theValidatedevent's scheduled run by setting theCancelfield of theEventArgs, but is that the only difference? Of what use is that? Thanks.In Christ, Aaron Laws http://ProCure.com

Rather than guessing what each event does why not take the time to actually read the documentation? control.validated[^] control.validating[^]

Well, if you think about what the words mean, validating can be cancelled as it's called during the validation process. Validated is called after.

Dear Mr. Nischalke, Yeah, I read that, I just can't figure out what the use might be.

It's painfully clear. When you validate, there's an event you can catch to do further validation and thus reject it. When it's been validated, there's an event so you can know if it passed or not.

You are going to have a very difficult time in this field if something so simple throws you off.

Dear Sirs, Thanks for your sharp responses. It didn't throw me off, but it seemed a bit redundant, that's all. The clarity is indeed blinding as to what happens, but the intent is still - to me - less than clear. I'm beginning to see why this might be necessary, but I still can't think of an example. A specific example could be great, if you please.
