SilverlightHost.IsLoaded Property

Silverlight

Gets a value that indicates whether the hosted Silverlight plug-in has finished loading.

Namespace:  System.Windows.Interop
Assembly:  System.Windows (in System.Windows.dll)

public bool IsLoaded { get; }

Property Value

Type: System.Boolean
true if the plug-in has finished loading; otherwise, false.

If the plug-in reports IsLoaded as true, then all specific Loaded events of the Silverlight object model within the Silverlight content area will already have been occurred, and the plug-in is ready for interaction.

The IsLoaded property is set to true after the XAML content in the Silverlight plug-in has completely loaded, but before the OnLoad event occurs. (The OnLoad event is only available in the JavaScript API, and is available to the HTML/browser DOM, NOT the Silverlight object model.)

The following code example demonstrates how to use this property.


// The Host object, which represents the host Silverlight plug-in.
System.Windows.Interop.SilverlightHost host = 
    Application.Current.Host;

// The following code demonstrates how to use the Host object
// to access other APIs in the System.Windows.Interop namespace.

// The IsVersionSupported method. This method is useful when
// you want to implement an upgrade experience in managed code.
bool isSupported = host.IsVersionSupported("2.0.30908.0");

// Read-only properties of the Host object.
System.Windows.Media.Color pluginBackground = host.Background;
bool loaded = host.IsLoaded;
Uri source = host.Source;

// The Settings object, which represents Web browser settings.
System.Windows.Interop.Settings settings = host.Settings;

// Read/write properties of the Settings object.
settings.EnableFrameRateCounter = true;
settings.EnableRedrawRegions = true;
settings.MaxFrameRate = 60;

// Read-only properties of the Settings object.
bool windowless = settings.Windowless;
bool htmlAccessEnabled = settings.EnableHTMLAccess;

// The Content object, which represents the plug-in display area.
System.Windows.Interop.Content content = host.Content;

// The read/write IsFullScreen property of the Content object.
// See also the Content.FullScreenChanged event.
bool isFullScreen = content.IsFullScreen;

// Read-only properties of the Content object. These properties do 
// not contain meaningful values until after the Content.Resized 
// event occurs for the first time. 
double actualWidth = content.ActualWidth;
double actualHeight = content.ActualHeight;
