onItemDragDrop Method (ImageViewer)


Raises the ItemDragDrop event.


JavaScript Syntax
ImageViewer.prototype.onItemDragDrop = function(_e_) 
TypeScript Syntax
onItemDragDrop(_e_: ImageViewerItemDragDropEventArgs): void; // protected 



The event data.


Raising an event invokes the event handler through a delegate. The OnItemDragDrop method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Note to Inheritors: When overriding OnItemDragDrop in a derived class, be sure to call the base class's OnItemDragDrop method so that registered delegates receive the event.


For an example on using the image viewer as the target for a drag/drop operation, refer to ItemDragDrop.

For an example on using the image viewer as the source of a drag/drop operation, refer to ImageViewerDragInteractiveMode.
