close MessageboxResul is NO how can I stop the process to close

Question

Hello,

How can I stop the process to close the window after a messagebox asking if the do want to close? and they answer no.

Thanks

Answer 1

Add a handler for the Closing event of the window and set the Cancel property of CancelEventArgs to true to prevent closing the window:

        private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
        {
            if (MessageBox.Show(this, "Are you sure?", Title, MessageBoxButton.YesNo) != MessageBoxResult.Yes)
                e.Cancel = true;
        }

Answer 2

Sorry it doesnt work to me.

Error 2 'System.EventArgs' does not contain a definition for 'Cancel' and no extension method 'Cancel' accepting a first argument of type 'System.EventArgs' could be found (are you missing a using directive or an assembly reference?) C

Answer 3

You have probably used the Closed event of the window instead of Closing. If you look at my example you'll see it has a CancelEventArgs while you're error shows EventArgs instead.
