Remarks

You can use the CollectingInk property to see if ink is being drawn on an InkOverlay object rather than monitoring the Stroke event.

Note: Because ink collection is happening on a different thread than your application code, it is possible that the CollectingInk property can change soon after you have checked it. Thus, your code may be operating under the assumption that the InkOverlay is not collecting ink, when in fact it is. If this occurs, an error is thrown. To be safe, put such code in a try-catch block.
