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.

namespace CSDesignerVerb
    // Associate MyDesigner with this component type using a DesignerAttribute
    public class Component1 : System.ComponentModel.Component

    // This is a designer class which provides designer verb menu commands for 
    // the associated component. This code is called by the design environment at design-time.
    internal class MyDesigner : ComponentDesigner
        DesignerVerbCollection m_Verbs;

        // DesignerVerbCollection is overridden from ComponentDesigner
        public override DesignerVerbCollection Verbs
                if (m_Verbs == null) 
                    // Create and initialize the collection of verbs
                    m_Verbs = new DesignerVerbCollection();

                    m_Verbs.Add( new DesignerVerb("First Designer Verb", new EventHandler(OnFirstItemSelected)) );
                    m_Verbs.Add( new DesignerVerb("Second Designer Verb", new EventHandler(OnSecondItemSelected)) );
                return m_Verbs;


        private void OnFirstItemSelected(object sender, EventArgs args) 
            // Display a message
            System.Windows.Forms.MessageBox.Show("The first designer verb was invoked.");

        private void OnSecondItemSelected(object sender, EventArgs args) 
            // Display a message
            System.Windows.Forms.MessageBox.Show("The second designer verb was invoked.");
