Gets the bounding rectangle of the painted element.
A Rectangle structure which specifies the element's boundaries.
If you try to access the Bounds property while an asynchronous operation is being performed, an exception will be thrown. When the operation is in progress, use the PivotCustomDrawThreadSafeEventArgs.Bounds property exposed by a thread-safe event parameter instead. To access the thread-safe event parameter, use the PivotCustomDrawEventArgs.ThreadSafeArgs property. To determine whether an asynchronous operation is being performed, use the pivot grid's IThreadSafeAccessible.IsAsyncInProgress property. For more information, see Asynchronous Mode.
