Question

Bind windows form [X] with exit

Asked by: csharp_learner

Hi I have a window form exit function which checks for text change before exiting the application.But I found out the windows [X] button on the top right ignores this and closes the apllication.
I was wondering if i could bind the both together so no matter how the user wants to exit the application it'll prform the text change check.

Change 3 line into your check function and use e.Cancel = true if you don't won't close application.
