'Declaration Public Event BeforeDisplayContextMenu As CancelableUIElementEventHandler
public event CancelableUIElementEventHandler BeforeDisplayContextMenu
The event handler receives an argument of type CancelableUIElementEventArgs containing data related to this event. The following CancelableUIElementEventArgs properties provide information specific to this event.
| Property | Description |
|---|---|
| Cancel (Inherited from System.ComponentModel.CancelEventArgs) | |
| UIElement | UIElement object. |
The context menu related events relied upon overriding the WndProc of the control. However, overriding this method adds a restriction that the control can only be used when unmanaged code permissions have been provided. Since this must be overriden at the time of compiling, the ContextMenu related events have been marked as obsolete and will be removed in a future version of the product. The events will no longer be invoked in the current version.
The BeforeDisplayContextMenu is fired before a context menu would be displayed. The CancelableUIElementEventArgs.UIElement returns the UIElement associated with the context menu so that a specific context menu could be displayed.
The BeforeDisplayContextMenu event may be canceled using System.ComponentModel.CancelEventArgs.Cancel property to prevent the control's popup menu from being displayed.
