public bool EnablePartialDrop { get; set; }
true to allow partial drop of annotation objects between multiple containers; otherwise, false. The default value is true.
This property is used to control the behavior of an annotation object that is dragged and then dropped so that part of it is outside any of the boundaries of any of the containers.
When the value is true (the default), the drop operation is successful but the object position will be adjusted so its boundary is completely enclosed inside the container it was dropped in (the target container).
When the value is false, the drop operation is aborted and the object is moved back to its source container and its position reset back to the original values before dragging began.
This property is only used when the value of AnnAutomation.EnableDragDrop is true.
