Hello,

How can i disable the Validating Event of all the controls of a form after a
click on a Cancel Button and close the Form?

Or how can fix the order of Validating events of the controls in a Form?

Thanks in advance.

Hi Pascal,
Sorry, I'm not clear about your problem. the Validating event of Control
is fired when the focus is moving off. It is not fired on form closing. If
you just want to disable the Validating events, you may try this way in
your From_Closing handler.

foreach(Control c in Controls)
c.CausesValidation = false;
Also, because Validation is fired on focus leave, there is no concept of
validation order.
If you want to validate the controls in some order when the form closing ,
you need add these
codes to the Form_Closing event.

Does this answer your problem?
If you still have problems on this issue, please be free to let me know.
Thanks!

Hi Ying-Shen,

this is not really an answer of my problem, but bow i understand why i can't
use the Validating Event for my purpose.
I thought of being able to use the Validating Events of each controls when
the user click on a Ok Button (to close the form) and disabling these events
if the user click on a Cancel Button; but it is not possible to reset the
CauseValidation property of each controls just after a click on a
CancelButton (and before the validating event of the control that had the
focus).

So i implement my own validating method that i called when i want.

Best regards,

Pascal
 
Try setting the CausesValidation property on the cancel button to false.
This should prevent the Control.Validating event from being fired in the
first place.
