  1. <Page  
  2.     x:Class="Message_Dialog_Demo.MainPage"  
  3.     xmlns=""  
  4.     xmlns:x=""  
  5.     xmlns:local="using:Message_Dialog_Demo"  
  6.     xmlns:d=""  
  7.     xmlns:mc=""  
  8.     mc:Ignorable="d">  
  9.     <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">  
  10.         <Button Content="Show Message Dialog" HorizontalAlignment="Left" Margin="308,197,0,0" VerticalAlignment="Top" Height="60" Width="138" Click="Button_Click"/>  
  11.     </Grid>  
  12. </Page>  
Now go to the coding part. Simply double-click the “Show Message Dialog” button and it will automatically create the event handler and it goes to the coding page.

Now write the following code to show the message dialog as “Hi Message dialog”.

To show the message dialog include the namespace given below:
  1. Using Windows.UI.Popups;  
Change the button click event to async as shown in the following.

Now write the following code in the button click event.

C# Code
  1. private async void Button_Click(object sender, RoutedEventArgs e)  
  2. {  
  3.       MessageDialog message = new MessageDialog("Hi Message dialog");  
  4.       await message.ShowAsync();  
  5. }  
The full code page looks like the following screen.
