Hi Arjun,

Message box? I assume you are working with MessageDialog class in Windows Store App.

Try following code:

        public MainPage()
        {
            this.InitializeComponent();
            Window.Current.SizeChanged += Current_SizeChanged;
        }

        MessageDialog md = new MessageDialog("asdsdsdsdada");
        IAsyncOperation<IUICommand> asyncOperation;
        void Current_SizeChanged(object sender, Windows.UI.Core.WindowSizeChangedEventArgs e)
        {
            asyncOperation.Cancel();
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            asyncOperation = md.ShowAsync();
        }

Hi Thanks For Your Reply,

Am Using 

var msgdialog = new Windows.UI.Popups.MessageDialog("Sample", "Title");
                            await msgdialog.ShowAsync();

in My View Model.

How Do i get to access This In My View?

  void Current_SizeChanged(object sender, Windows.UI.Core.WindowSizeChangedEventArgs e)
        {
            asyncOperation.Cancel();
//This Code Snippet is in my XAML.cs File.
        }

Thanks

Hi Arjun,

Make sure the asyncOperation can be accessed from your code, make it static or public.

I don't know how you manage the code, but if you simply test the code I provided by a blank app, you should be able to find out how to use it.

Hi Jamles,

Thanks for your reply,

yes like u said i made that async operation Public. 

But in My App After Showing PopUp It is Navigating to Other Page.

That Time It is Not Cancelling the async Operation .

Answer 5

Not quite understand what do you mean by "But in My App After Showing PopUp It is Navigating to Other Page."? Your initial question is on how to hide the MessageDialog while the app change its view size, I cannot see why navigating block your MessageDialog. 

I suppose each time your screen size changed, the MessageDialog will disappear immediately.

If you really need cancel the async operation before navigating to another page, try to re-write the OnNavigateFrom method.
