This method is called while an item is being loaded and the image data has not been obtained yet.
Derived classes can render a visual hint to the user to indicate that the item is being loaded.
You should encapsulate the code inside this method with a try/catch and handle the error correctly. This method will not automatically fire the ItemError event.
For an example, refer to ImageViewerVirtualizer.
