Namespace:DevExpress.Web.ASPxTreeList.Scripts

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type ASPxClientTreeListContextMenuEventArgs containing data related to this event.

The following ASPxClientTreeListContextMenuEventArgs properties provide information specific to this event.
Property Description
cancel Gets or sets whether to invoke the browser's context menu.
htmlEvent Gets a DHTML event object that relates to the processed event.
objectKey Gets a value that identifies the right-clicked object.
objectType Identifies which tree list element has been right-clicked.

Expanded Remarks

The ContextMenu event is raised when an end-user has right-clicked within an ASPxTreeList, and enables you to invoke a context menu. The event parameter provides the following properties:

  • objectType

    Identifies which tree list element ('Header' or 'Node') has been right-clicked.
  • objectKey

    Returns a key value that identifies the clicked node. If a column header has been right-clicked, this property returns the column's index.
  • htmlEvent

    Gets a DHTML event object that relates to the processed event.
  • cancel

    Specifies whether to invoke the browser's context menu.

Expanded Example

This example demonstrates how to display a context menu. When an end-user right-clicks within the ASPxTreeList, the client-side ContextMenu event is fired. In this example, the context menu is invoked when a node is right-clicked.
