Here's an example:
public class TestObjectContextMenu
{
public class MyContextMenu : ContextMenuExtension
{
private MenuItem m_main = new MenuItem("MAIN MENU");
private MenuItem m_sub0 = new MenuItem("SUBMENU 0");
private MenuItem m_sub1 = new MenuItem("SUBMENU 1");
private MenuItem m_sub2 = new MenuItem("SUBMENU 2");
static public bool m_bShowExtraMenus = true;
public MyContextMenu()
{
this.Title = "Test";
this.MenuItems.Add(m_main);
m_main.MenuItems.Add(m_sub0);
m_main.MenuItems.Add(m_sub1);
this.Popup += new EventHandler(OnUpdateMenu);
m_sub0.Click += new EventHandler(OnClick);
m_sub1.Click += new EventHandler(OnClick);
m_sub2.Click += new EventHandler(OnClick);
}
void OnClick(object sender, EventArgs e)
{
}
void OnUpdateMenu(object sender, EventArgs e)
{
ContextMenuExtension cme = (ContextMenuExtension) sender;
if (MyContextMenu.m_bShowExtraMenus)
{
if (!m_main.MenuItems.Contains(m_sub2))
{
m_main.MenuItems.Add(m_sub2);
}
}
else
{
if (m_main.MenuItems.Contains(m_sub2))
{
m_main.MenuItems.Remove(m_sub2);
}
}
// toggle
MyContextMenu.m_bShowExtraMenus =
!MyContextMenu.m_bShowExtraMenus;
}
};
[CommandMethod("MENUTEST")]
public static void DoIt()
{
Application.DocumentManager.MdiActiveDocument.Editor.WriteMessage("Registering
Object Context menu for circle...\n");
MyContextMenu cme = new MyContextMenu();
Application.AddObjectContextMenuExtension(RXObject.GetClass(typeof
(Circle)), cme);
}
}
