RenderItemPlaceholder Method (ImageViewerVirtualizer)
Summary
Render any optional place holder before the image data is obtained.
Syntax
abstract void RenderItemPlaceholder(ImageViewerRenderEventArgs e)
MustOverride Sub RenderItemPlaceholder(ByVal e As ImageViewerRenderEventArgs)
virtual void RenderItemPlaceholder(ImageViewerRenderEventArgs^ e) abstract
Parameters
e
Render event arguments to use.
Remarks
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.
Example
For an example, refer to ImageViewerVirtualizer.
