DynamicMenu Class—ArcGIS Pro

Represents a menu that is populated at run-time. This is an abstract class.

Syntax

C#
Visual Basic (Declaration)

public abstract class DynamicMenu : PlugIn, System.ComponentModel.INotifyPropertyChanged

Public MustInherit Class DynamicMenu 
   Inherits PlugIn
   Implements System.ComponentModel.INotifyPropertyChanged

Remarks

Unlike declaratively defined menus, dynamic menus are populated at run-time. Derived classes must add items in their OnPopup override which is invoked before the menu opens. Dynamic menus may contain simple items consisting of a caption and image, or references to existing DAML controls including other dynamic menus. The OnClick override is invoked with the specified index when an item is clicked. All menu items are cleared after the popup closes.

Dynamic menus can reside directly on the ribbon or on other menus. If the dynamic menu is on a menu and the inline attribute is set to true, the items will be added directly onto the hosting menu instead of being added to a pull-right submenu.

Declaring Dynamic menus in DAML:

            <dynamicMenu caption="Acme Menu " 
                         className="DynoMenu" 
                         id="acme_dynoMenu" 
                         largeImage="pack://application:,,,/ProTestApp;component/Images/MenuImage32.png" 
                         smallImage="pack://application:,,,/ProTestApp;component/Images/MenuImage16.png" >
              <tooltip heading="Heading" image="pack://application:,,,/Acme;component/Images/MenuImage16.png">Some text</tooltip>
            </dynamicMenu>

Example

internal sealed class DynoMenu : ArcGIS.Desktop.Framework.Contracts.DynamicMenu
{
  internal delegate void MathAction(double number);
            
  protected override void OnPopup()
  {
    double angle = 28.0;
            
    MathAction action = Test;
            
    this.Add("item 1", @"pack://application:,,,/Images/Image1.png", true, true, false, action, angle);
    this.Add("item 2", @"pack://application:,,,/Images/Image2.png");
    this.AddSeparator();
    this.AddReference("acme_basicButton");
    this.AddReference("acme_basicMenu");

  private void Test(double angle)
  {
    System.Windows.MessageBox.Show(angle.ToString());
  }
