Remarks

This event fires on the source object after the event. The ondrag event fires throughout the drag operation, whether the selection being dragged is over the drag source, a valid target, or an invalid target.

Calls the associated event handler if there is one.

To invoke this event, do one of the following:

Drag a text selection or object within the client.
Drag a text selection or object to another client.
Drag a text selection or object to a drop target in another application.
Drag a text selection or object to the system desktop.

Examples

This example shows when and where each event fires during a drag-and-drop operation by listing each event and the name of the object firing it in a list box.
