Introduction

I am going to explain how to create a popup menu and message dailogbox in Windows Store apps. When we open any application, there is a menu bar. When we click on any menu item, the popup menu will be shown from which we can select any popup menu item. In this tip, I explain how to create a Popup menu. The message box here is fully user-defined, we can add the commands to the message box and also add an action with it.

1. Create a new blank app name Popupmenu_N_Msgdialogbox:

   

2. Add Button and Popup control in MainPage.xaml:

           <Button Content="Show Popup" 
       Click="ShowPopup" Margin="120,69,0,0" VerticalAlignment="Top"/>
           <Popup  VerticalOffset="10" 
           HorizontalOffset="300" x:Name="StandardPopup" 
   IsLightDismissEnabled="True">
               <Border BorderBrush="{StaticResource ApplicationForegroundThemeBrush}" 
               BorderThickness="2" 
                           Background="{StaticResource ApplicationPageBackgroundThemeBrush}" 
                           Width="212" Height="200">
                   <StackPanel HorizontalAlignment="Center" 
                   VerticalAlignment="Center">
                       <TextBlock Text="Simple Popup" 
                       FontSize="24.667" HorizontalAlignment="Center"/>
                       <Button Content="Close" Click="ShowPopupClose" 
                       HorizontalAlignment="Center"/>
                   </StackPanel>
               </Border>
           </Popup>

3. And in MainPage.Xaml.cs file, add this code:

           private void ShowPopup(object sender, RoutedEventArgs e)
           {
               if (!StandardPopup.IsOpen) { StandardPopup.IsOpen = true; }
           }
   
           private void ShowPopupClose(object sender, RoutedEventArgs e)
           {
               if (StandardPopup.IsOpen) { StandardPopup.IsOpen = false; }
    }

4. The output of this code is as follows:

   

5. Add new Button for message dailogbox:

   <Button Content="MessageDialog Box" Click="MessageDialogBox" HorizontalAlignment="Left" Margin="120,176,0,0" 
                   VerticalAlignment="Top&rdquo; Width="238"/>

7. And add this code in Mainpage.xaml.cs file:

   private async void MessageDialogBox(object sender, RoutedEventArgs e)
           {
               var messagedialog = new MessageDialog("No internet connection has been found.");
               messagedialog.Commands.Add(new UICommand("Try again"));
               messagedialog.Commands.Add(new UICommand("Close"));
               await messagedialog.ShowAsync();
    }
