Gets a value that indicates whether the specified URI can be loaded.

Namespace:  System.Windows.Navigation
Assembly:  System.Windows.Controls.Navigation (in System.Windows.Controls.Navigation.dll)

Syntax

'Declaration
Public Function CanLoad ( _
    targetUri As Uri, _
    currentUri As Uri _
) As Boolean

public bool CanLoad(
    Uri targetUri,
    Uri currentUri
)

Parameters

  • currentUri
    Type: System.Uri
    The URI of the page that is currently loaded.

Return Value

Type: System.Boolean
true if the URI can be loaded; otherwise, false.

Implements

INavigationContentLoader.CanLoad(Uri, Uri)

Remarks

Typically, you will not call this method directly unless you implement an alternative to the Silverlight navigation system.

This method is called by the navigation system to determine whether a particular URI is available for navigation. For example, this method is used to determine whether a URI is in the correct format. If the BeginLoad method is called with a URI that cannot be loaded, the Frame.NavigationFailed event occurs. If the event is not handled, an exception is thrown.
