The only way to cancel the asynchronous operation of this method is to cancel all asynchronous operations. Contrast this with the other overload of this method: GetPageAsync(Int32, Object).

This method raises the GetPageCompleted event. The DocumentPage is passed to the event as one of the event arguments. See GetPageAsync(Int32, Object) for how to use this method to get the page.
