Property Value

A value that specifies whether ink is currently being drawn on an InkPicture control.

Value	Meaning
true	Ink is being drawn on the InkPicture control.
false	Ink is not being drawn on the InkPicture control.

Remarks

You can use the CollectingInk property to see if ink is being drawn on an InkPicture control 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 InkPicture 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.
