mark Field

ImageGear.Web.UI Library > ImageGear.Web.UI Namespace > MouseEvent class : mark Field
If the target of the event was a mark, this property will hold a reference to that mark. Otherwise it will be null. Note that, for some mouse tools, the mouse up event will not include a reference to a mark because the mouse tool displayed the selection between the mark and the cursor.
