Remarks

An exception is raised if you change the EditingMode property while ink is being collected. To avoid this conflict, make sure the CollectingInk property is false before changing the EditingMode property.

For more information about erasing ink, see Erasing Ink with the Pen.

Examples

This example shows an event handler for a ListBox control that changes the EditingMode property for an InkPicture object.

The EditingMode property cannot be changed while the object is collecting ink. Because ink collection is handled on a separate thread from your application code, the CollectingInk property can change to true while your application code is operating under the assumption that it is still false. To handle this contingency, access to the EditingMode property should be contained within a try-catch block.
