How to hide MDI children instead of closing them?

[John]

Hi,

I have an MDI application. The MDI children are instantiated when the
form loads and the user has the ability to show them or to hide them.
I trap the Closing event on the children and set e.Hide = true and
then call Hide() to hide the form.

The problem is when the application needs to exit. When the user
clicks the X on the MDI parent the Closing event is fired on all the
children *BEFORE* it's fired for the parent. The children cancel the
close so the application doesn't exit.

What's the right way to make this work?

Thanks,
John

Hi John,

Putting 'Application.Exit()' in the Closing event of the MDI form should do
the trick.

HTH,

Thanks for your reply.

The Closing event in the parent form never gets called if any of the
children forms sets e.Cancel = true.

Am I missing something?

Thanks,
John

MSDN library - Closing event:
"To force all MDI parent and child forms to close, set the
System.Windows.Forms.ClosingEventArgs.Cancel property to false in
the MDI parent form."
