Remarks

This class is infrastructure, and provides the underlying run-time value for the behavior when you specify CacheMode="BitmapCache" in XAML markup, or create a new BitmapCache in code to set UIElement.CacheMode.

Examples

Use any of these syntax forms to set UIElement.CacheMode to a value other than the null default. Don't do this routinely without testing first, see "Remarks" in UIElement.CacheMode.


<Canvas CacheMode="BitmapCache">
  ...
</Canvas>


canvas1.CacheMode = new BitmapCache(); //canvas1 is an existing named element in UI
