When you are working on a Windows Phone project, it is very common to define navigation between pages. The most common method of defining navigation is to right-click an object on the artboard, click Navigate to, and then click the page to which you want to navigate. You can also use the built-in NavigateToPageAction behavior to define the navigation between pages.
To add a NavigateToPageAction to a Windows Phone project
In the Assets panel, click Behaviors, and then drag NavigateToPageAction onto the object that you want to apply the action to. The Common Properties category appears in the Properties panel.
In the Common Properties category, in the TargetPage drop-down list, select the page that you want to navigate to.
