A designer verb is a menu command linked to an event handler. Designer verbs are added to a component's shortcut menu at design time. In Visual Studio, each designer verb is also listed, using a LinkLabel, in the Description pane of the Properties window.

NoteNote

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

The following code example demonstrates how to create DesignerVerb objects and add them to the design-time shortcut menu for a component.

using System;
using System.ComponentModel;
using System.ComponentModel.Design;
using System.Collections;

/* This sample demonstrates a designer that adds menu commands
    to the design-time shortcut menu for a component.

    To test this sample, build the code for the component as a class library, 
    add the resulting component to the toolbox, open a form in design mode, 
    and drag the component from the toolbox onto the form. 

    The component should appear in the component tray beneath the form. 
    Right-click the component.  The verbs should appear in the shortcut menu.
