How to override onclose event on WPF?

Question

I\'m trying to override the onclose event on WPF, this is my code so far:

protected override void OnClosing(System.ComponentModel.CancelEventArgs e)
{
               


        

Answer 1

You are asking it not to close by setting e.Cancel = true. Just don't do that.

Answer 2

The application never closes because you are setting e.Cancel to true.

Try

protected override void OnClosing(System.ComponentModel.CancelEventArgs e)
{
       //do my stuff before closing

       base.OnClosing(e);       
}
