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)

'Declaration
Public ReadOnly Property IsLoaded As Boolean

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. 
Dim host As System.Windows.Interop.SilverlightHost = _
    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. 
Dim isSupported As Boolean = host.IsVersionSupported("2.0.30908.0")

' Read-only properties of the Host object. 
Dim pluginBackground As System.Windows.Media.Color = host.Background
Dim loaded As Boolean = host.IsLoaded
Dim source As Uri = host.Source

' The Settings object, which represents Web browser settings. 
Dim settings As System.Windows.Interop.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. 
Dim windowless As Boolean = settings.Windowless
Dim htmlAccessEnabled As Boolean = settings.EnableHTMLAccess

' The Content object, which represents the plug-in display area. 
Dim content As System.Windows.Interop.Content = host.Content

' The read/write IsFullScreen property of the Content object. 
' See also the Content.FullScreenChanged event. 
Dim isFullScreen As Boolean = 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. 
Dim actualWidth As Double = content.ActualWidth
Dim actualHeight As Double = content.ActualHeight
