preventing validation in OnClosing

[Alex Bink]

Hi,

Anyone knows how to prevent the validating event of a control to be fired
when the user clicks the close button? The OnClosing event of the form seems
to be to late and setting the form's CausesValidatio n property to false
doesn't seem to help either...

Thanks...

Alex,

The only suggestion I've seen from Microsoft is to go through your
entire form in your OnClosing event, setting CausesValidatio n on every
control to false. I consider this completely lame.

I suggest creating a bool flag in your form to act as a "don't bother
validating" flag:

private bool dontBotherValid ating = false;

then every _Validating event handler looks like this:

private void aControl_Valida ting(object sender, System.EventArg s e)
{
if (!dontBotherVal idating)
{
.... do validation stuff here ...
}
}

then, in OnClosing, you can add as the first line:

this.dontBother Validating = true;

I know it's not pretty, but I have never found a way to flush pending
Validating events... you seem to have no choice but to have them fire,
so I just accepted that fact and handled the problem within my
Validating event handlers.
