VEShape.GetID Method

Bing Services

Gets the internal identifier of the VEShape object.


VEShape.GetID();

Returns

A String object representing the internal identifier of the VEShape object.

Returns

Use this identifier when working with VEShape object events. A VEShape object only has an identifier when it has been added to a layer. If you try to get the identifier of a VEShape object that is not part of a layer, the VEShape.GetID method returns null.
