Closing child form in MDI application
Posted on 2006-07-11
I have a MDI application, in child form class I write event handler to handle FormClosing event. In the event handler I show a message box to ask user to save their changes to the document. I write code to do the task as follow. If user selects Yes the document will be save and the form will be closed, if user selects No then form will be close without saving document, and if user select Cancel the Cancel property of FormClosingEventArgs will be set to true and do nothing. But when I run my application, when message is promted I select No in some form and select Cancel at the message of last form. If it is correct then there is one child form in my application but in my application, all child form still remaining and not closed.
Please tell me why and let me know the way to solve this problem.
thanks and best regard.
