The Basic Layout Controls in WP7

As you are probably aware, pages in Windows Phone 7/WP7 are created using XAML (eXtensible Application Markup Language). Unlike other mobile platforms, the highly structured nature of XAML includes several different controls that provide different layout methods. This is somewhat of a departure from other platforms where controls are placed on screen/page using an absolute position only. Absolute positioning does have its merits; however, as soon as you need to allow your application to run on multiple screen sizes you will need to make changes to your app to support the different screen size. Once you become familiar with other schemes of layout you should find yourself needing absolute positioning less and less. Listed below are the basic layout controls available for WP7.


The first layout method that can be used is the Canvas, which provides the ability to perform absolute layouts. Yes, WP7 does provide support for absolute layouts; however, it really isn't recommended for the reasons described above. Nonetheless, it is available and provides you with the ability to perform X, Y positioning of controls within the Canvas. The Canvas is good to get a general idea of how you want your screen to look; then it is a good idea to go back and recreate using the other layout controls listed below. The image below shows a simple layout with two controls inside the canvas as well as the corresponding XAML for the image.

Stack Panel

The Stack Panel allows you to place controls either horizontal or vertical, which is one of the more common layout methods you will find used. At first this may not seem useful, but when you consider the fact that you can embed one stack inside another, it is very useful. If you start with a vertical stack panel and you populate it with multiple items you wind up with the makings of a list as shown below with the accompanying XAML.

Vertical Stack Panel

Next, if you replace the TextBlock with a Horizontal StackPanel you are able to create a rudimentary grid and/or more complex elements within your list. If you specifically need to perform Grid style layout then you need to look at the Grid layout below.


The Grid Layout basically allows you to group your controls into rows and columns similar to HTML tables. The Grid Layout is used in many locations including the basic templates available in Microsoft Visual Studio for Windows Phone 7 as shown in the screenshot below and the accompanying XAML.

Scroll View

Finally we have the Scroll View which is technically a layout, but works best when accompanied with one of the others below. Basically, the Scroll View provides you with the ability to support horizontal or vertical scrolling. For instance if you were to combine the Stack Panel above with a Scroll View you can further the list capabilities of the basic list with a Stack Panel. If you were to dig into the XAML used for many applications you would find the lists were built using the Vertical Stack Panel wrapped in a Vertical Scroll View.


With the above controls it should be easy to see how much power you have at your disposal when it comes to building layouts for your Windows Phone 7 applications. The important thing to remember here is that these layout controls can be embedded within one another, allowing you a lot of flexibility. I hope you can see this flexibility nearly completely eliminates the need absolute style layouts provided by the Canvas. Thus if you eliminate the need for the Canvas today you should be able to provide better future capability for your app on future hardware.
