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.

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.
