MessageboxResult is Cancel when user clicks back button

Question

I noticed that if some MessageBox appears and you even just have a OK button on it and the user clicks the back button from Windows Phone 7, you will receive Cancel in MessageBoxResult.

Anybody experienced it?

Answer 1

        MessageBoxResult m = MessageBox.Show("something", "something", MessageBoxButton.OK);
        if (m == MessageBoxResult.Cancel)
        {
            MessageBox.Show("cancelled!");
        }
        else 
        {
            MessageBox.Show("not cancelled!");
        }

Edit: Just found some information here

An excerpt

When the user closes the MessageBox in a non-standard manner (e.g. by pressing the Back button), the result that is automatically passed as a response is MessageBoxResult.Cancel, even if no Cancel button is pressed.

From what I can tell from the article, MessageBoxResult.Cancel is what you get when using Windows Phone 7.
But, when tested in a Windows Phone 7.1(Mango) application, I got a MessageBoxResult.None
