In JScript, you can handle the events defined by a class, but you cannot define your own.
<object DragStarted="DragStartedEventHandler" .../>
The following example shows how to assign an event handler for the DragStarted event to a Thumb control, and how to define the event handler. For the complete sample, see Drag Functionality Sample.
