D3DImage::IsFrontBufferAvailableChanged Event

Occurs when the IsFrontBufferAvailable property changes.

Namespace:  System.Windows.Interop
Assembly:  PresentationCore (in PresentationCore.dll)
XMLNS for XAML: Not mapped to an xmlns.

public:
 event DependencyPropertyChangedEventHandler^ IsFrontBufferAvailableChanged {
	void add (DependencyPropertyChangedEventHandler^ value);
	void remove (DependencyPropertyChangedEventHandler^ value);
}
<object IsFrontBufferAvailableChanged="DependencyPropertyChangedEventHandler" .../>

Handle the IsFrontBufferAvailableChanged to be notified when the status of the front buffer changes. How your application responds to the front buffer becoming unavailable depends on whether WPF is enabled to fall back to software rendering. The SetBackBuffer method has an overload that takes a parameter that specifies whether WPF falls back to software rendering. For more information, see the remarks in the D3DImage class.
