DesignerVerb Class

Represents a verb that can be invoked from a designer.

Namespace:  System.ComponentModel.Design
Assembly:  System (in System.dll)

[PermissionSetAttribute(SecurityAction.LinkDemand, Name = "FullTrust")]
[HostProtectionAttribute(SecurityAction.LinkDemand, SharedState = true)]
[PermissionSetAttribute(SecurityAction.InheritanceDemand, Name = "FullTrust")]
public class DesignerVerb : MenuCommand

The DesignerVerb type exposes the following members.

Public methodDesignerVerb(String, EventHandler)Initializes a new instance of the DesignerVerb class.
Public methodDesignerVerb(String, EventHandler, CommandID)Initializes a new instance of the DesignerVerb class.

Public propertyCheckedGets or sets a value indicating whether this menu item is checked. (Inherited from MenuCommand.)
Public propertyCommandIDGets the CommandID associated with this menu command. (Inherited from MenuCommand.)
Public propertyDescriptionGets or sets the description of the menu item for the verb.
Public propertyEnabledGets a value indicating whether this menu item is available. (Inherited from MenuCommand.)
Public propertyOleStatusGets the OLE command status code for this menu item. (Inherited from MenuCommand.)
Public propertyPropertiesGets the public properties associated with the MenuCommand. (Inherited from MenuCommand.)
Public propertySupportedGets or sets a value indicating whether this menu item is supported. (Inherited from MenuCommand.)
Public propertyTextGets the text description for the verb command on the menu.
Public propertyVisibleGets or sets a value indicating whether this menu item is visible. (Inherited from MenuCommand.)

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodInvoke()Invokes the command. (Inherited from MenuCommand.)
Public methodInvoke(Object)Invokes the command with the given parameter. (Inherited from MenuCommand.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Protected methodOnCommandChangedRaises the CommandChanged event. (Inherited from MenuCommand.)
Public methodToStringOverrides ToString. (Overrides MenuCommand.ToString().)

Public eventCommandChangedOccurs when the menu command changes. (Inherited from MenuCommand.)

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 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.

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.");
