XAML Values

  • singleContentElement
    Exactly one object element for a class that derives from UIElement. This is almost always an object that can take child elements (such as a Panel) so that multiple elements can be added to content. XAML processing of a UserControl has a special behavior that sets this content to the otherwise protected Content property.

The Page type exposes the following members.

Constructors

  Name Description
Public method Page Initializes a new instance of the Page class.

Methods

  Name Description
Public method AddHandler Adds a routed event handler for a specified routed event, adding the handler to the handler collection on the current element. Specify handledEventsToo as true to have the provided handler be invoked for routed event that had already been marked as handled by another element along the event route. (Inherited from UIElement.)
Public method ApplyTemplate Loads the relevant control template so that its parts can be referenced. (Inherited from Control.)
Public method Arrange Positions child objects and determines a size for a UIElement. Parent objects that implement custom layout for their child elements should call this method from their layout override implementations to form a recursive layout update. (Inherited from UIElement.)
Protected method ArrangeOverride Provides the behavior for the Arrange pass of Silverlight layout. Classes can override this method to define their own Arrange pass behavior. (Inherited from FrameworkElement.)
Public method CaptureMouse Sets mouse capture to a UIElement. (Inherited from UIElement.)
Public method CheckAccess Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)
Public method ClearValue Clears the local value of a dependency property. (Inherited from DependencyObject.)
Public method Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)

Remarks

The Page class enables you to easily create a Silverlight application that supports navigation. You use the Page class to create pieces of content that support navigation from within a Frame. You can create as many different pages as needed to present the content in your application and then navigate to those pages from the frame.

With the Page class, you can support not only navigation to a page of content, but also navigation within that content by providing fragment values. The NavigationContext property provides query string values that you can use to pass values to the page. For example, you may retrieve a query string value to determine which record from a data set to display. When combined with URI mapping, you can create user-friendly URIs that request specific content.

The NavigationService property provides access to the service used by the host to navigate to the page. From within the page, you can navigate to another page or navigate to a new representation of the current page.

You use the NavigationCacheMode property to specify the caching behavior for a page.

You override any of the following methods to add code that responds to navigation events:

NoteNote:

The Page control is available as part of the libraries in the Silverlight Software Development Kit (SDK). For more information, see the Silverlight Tools.

Examples

The following example shows a Silverlight page that retrieves data from a data service and displays that data. The page displays information about a product based on a value in the query string. The OnNavigatedTo method is overridden to obtain a query string value from the NavigationContext object. The NavigationService object for this page is accessed to determine if forward and back navigation is available.

The first part of the example shows the frame that hosts the page and the URI mappings for the request and query string values.

<sdk:Frame 
       x:Name="ContentFrame" 
       Style="{StaticResource ContentFrameStyle}" 
       Source="/Home" 
       Navigated="ContentFrame_Navigated" 
       NavigationFailed="ContentFrame_NavigationFailed">

        <sdk:UriMapper>
            <sdk:UriMapping 
                Uri="/ProductDetail/{productid}" 
                MappedUri="/Views/ProductDetail.xaml?ProductId={productid}"/>
            <sdk:UriMapping 
                Uri="/Reports/{type}/{selection}" 
                MappedUri="/Views/ReportsPage.xaml?type={type}&amp;selection={selection}"/>
            <sdk:UriMapping 
                Uri="/{pageName}" 
                MappedUri="/Views/{pageName}.xaml"/>
        </sdk:UriMapper>
    </sdk:Frame.UriMapper>
</sdk:Frame>

The second part shows the XAML page that displays the data.

<!-- NOTE: 
  By convention, the sdk prefix indicates a URI-based XAML namespace declaration 
  for Silverlight SDK client libraries. This namespace declaration is valid for 
  Silverlight 4 only. In Silverlight 3, you must use individual XAML namespace 
  declarations for each CLR assembly and namespace combination outside the scope 
  of the default Silverlight XAML namespace. For more information, see the help 
  topic "Prefixes and Mappings for Silverlight Libraries".
