Remarks
This event is raised through Virtualizer after LoadItem returns the image data of an item. The viewer will automatically invalidate the item area so it can be re-rendered and the place holder replaced with the actual image data.
You can use subscribe to this event to perform the following:
-
Track when an image data of an item is ready for debugging or logging purposes.
-
Replace the default implementation described above. Set the value of ImageViewerVirtualizerEventArgs.IsHandled to true to stop the viewer from invalidated the area of the item to be re-rendered.
