Adding an Application Bar to your XAML Metro Applications.

2 minute read



We are all familiar with the Application Bars in Windows Phone 7…


It can be achieved with a few lines of code as shown below:

<phone:PhoneApplicationPage.ApplicationBar>      <shell:ApplicationBar>          <shell:ApplicationBarIconButton IconUri="/icons/download.png" IsEnabled="True" />          <shell:ApplicationBarIconButton IconUri="/icons/settings.png" IsEnabled="True" />          <shell:ApplicationBar.MenuItems>              <shell:ApplicationBarMenuItem x:Name="mnuReturnToHome" Text="return to home" Click="mnuReturnToHome_Click" />                        </shell:ApplicationBar.MenuItems>      </shell:ApplicationBar>  </phone:PhoneApplicationPage.ApplicationBar>

We want to do the same thing with our new XAML Metro Applications. The good news is that it is just as easy as the Windows Phone 7 with a few other cool features.

Let’s get started…

Fire open Visual Studio 11 and select File->New Project. Then select Visual C# –> Windows Metro Style –> Application and give it a name and hit OK.


Once the MainPage.xaml loads then replace the Grid with the following code snippet:

<Grid x:Name="LayoutRoot" Background="#FF0C0C0C">      <ApplicationBar VerticalAlignment="Bottom">          <StackPanel Orientation="Horizontal">              <Button Content="Exit" x:Name="btnExit" />          </StackPanel>      </ApplicationBar>  </Grid>
Now you should be able to run the project with a simple Ctrl+F5 or from the Debug menu. 


But you will quickly notice that all you have is a black screen.


Note: Black screenshot added for laughs. Smile

App bars are transient by default which means they start out hidden and only appear in response to a gesture or in this case a right mouse click. If you right click on the application (if using an emulator or a non-tablet device) you will see the application bar appear.


You can also press CTRL+ALT+A if you are a keyboard kind of guy/gal.

I want my app bar always visible!

You can make the app bars display at all times by setting the IsPersistent property to True.

<Grid x:Name="LayoutRoot" Background="#FF0C0C0C">         <ApplicationBar VerticalAlignment="Bottom" IsPersistant="True">             <StackPanel Orientation="Horizontal">                 <Button Content="Exit" x:Name="btnExit" />             </StackPanel>         </ApplicationBar>     </Grid>

How do you change the way app bars are dismissed?

You can change the way that app bars are dismissed by setting the DismissMode property.


From the documentation:

  • The default value is EdgeSwipe which requires an edge swipe gesture right-click or CTRL+ALT+A.
    LightDismiss causes the app bar to disappear when the user interacts main part of the app and
    TimeDelay causes the app bar to disappear after a specified delay.

In the sample code below you will see that we set two properties. The DismissMode and Delay. (We set this example to hide the application bar after 5 seconds).

<ApplicationBar Background="White" VerticalAlignment="Bottom" DismissMode="TimeDelay" Delay="5000">     <StackPanel>           <Button Content="Bottom" Background="Black" />     </StackPanel>  </ApplicationBar>

Is my app bar limited to the bottom?

No You may change the VerticalAlignment to any of the following values. The only one that I found beneficial was the Top or Bottom. 


As you can see several options exist.

Can I have both a Top Application Bar and a Bottom Application Bar?

Sure just add in the code similar to the following:

<Grid x:Name="LayoutRoot" Background="#FF0C0C0C">            <!--Top App Bar-->      <ApplicationBar Background="White" VerticalAlignment="Top" DismissMode="TimeDelay" Delay="5000
