Question

I have a wpf project which has couple of windows, whne i navigate from one window to other i just hide one window and create instance of other if not created already, otherwise just make it visible

in all windows there is window closing event handler

 private void Window_Closing_1(object sender, CancelEventArgs e)
    {
         {

        string message = "You are trying to close window " + this.Name + " .Are you sure?";
        string caption = "Exit";
        MessageBoxButton buttons = MessageBoxButton.YesNo;
        MessageBoxImage icon = MessageBoxImage.Question;
        if (MessageBox.Show(message, caption, buttons, icon) == MessageBoxResult.Yes)
        {
            App.Current.Shutdown();

        }
        else
        {
         MessageBox.Show("Closing aborted");

        }
    }

but problem is this event is there in every window so when i close it lots of other prompt from other window which are invisible also show up. Is there a way to avoid other pronpts if i close in only one window?

Answer 1

just create a static method in another class to handle closing of forms.

public class X 
{
    private static bool isClosingHandled = false;

    public static void HandleClose()
    {
        //// app closing logic
        isClosingHandled = true;
    }
}

private void Window_Closing_1(object sender, CancelEventArgs e)
{
    X.HandleClose();   
}
