RadTreeViewContextMenuEventArgs

Class

Provides data for the ContextMenuItemClick event of the RadTreeView control. This class cannot be inherited.

The ContextMenuItemClick event is raised when an item in the RadTreeViewContextMenu of the RadTreeView control is clicked.

A click on a RadTreeViewContextMenu item of the RadTreeView makes a postback only if an event handler is attached to the ContextMenuItemClick event.
