AcceptButton closes Form on Failure

[Christian Wilhelm]

Hi!

I have an AcceptButton on my Form. With pressing this Button some checks are
performed and only when they are all okay, then the Form should close.

Can I set this up in some way?
E.g. abort the Closing-Process of the Form...

Thank U very much,
Christian

Sorry,

I have found my Failure.
The Button's DialogResult-Attribute was setted to "OK" by the Designer.
I have changed this to None and now it works.

Thank U,
Christian

Christian,
The other possibilities would be to leave it DialogResult.OK and handle
form's Closing event. Here you can cancel closing if something's wrong

Hi Stoitcho,

thank you for your answer.
Only of reasons of curiousity: how can I do this, can you give me a keyword?

Thank you very much,

Forms have Closing event you can ether hook on it or override OnClosing
virtual method. The event args object of this event has porperty Cancel. If
you set this property to true the form won't close.

Closing event is fired whenever the form closes.
