Sets the value of the CachingHint attached property on a specified dependency object.
Assembly: PresentationCore (in PresentationCore.dll)
public: static void SetCachingHint( DependencyObject^ target, CachingHint cachingHint )
By default, WPF does not cache the rendered contents of DrawingBrush and VisualBrush objects. In static scenarios, where neither the contents nor the use of the brush in the scene is changing, not caching provides a benefit because it conserves video memory. When a brush with static content is used in a non-static way, the default behavior of WPF is to re-render all the content of the brush every frame, even though the content is unchanging. For example, this will happen when a static DrawingBrush or VisualBrush is mapped to the surface of a rotating 3D object. Re-rendering the static content can have a negative impact on performance.
The CacheInvalidationThresholdMinimum and CacheInvalidationThresholdMaximum property values are relative-size values that determine when the TileBrush object should be regenerated because of changes in scale. For example, when the CacheInvalidationThresholdMaximum property is set to 2.0, the cache for the TileBrush needs to be regenerated only when its size exceeds two times the size of the current cache.
Use this method to set the CachingHint attached property in code.
