AutoCAD Context Menu Without Object Selection

[traiduong014969]

I’ve been working with context menus, and I’m encountering an issue with my code. Currently, I must select object first for the context menu appears. However, I’d like the context menu to appear directly when I right-click the mouse."

This is my example code.

So someone can help me fix this

Thank you !

using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.Windows;
using System;

public class Commands : IExtensionApplication
{
    public void Initialize()
    {
        
        CountMenu.Attach();
    }

    public void Terminate()
    {
        
        CountMenu.Detach();
    }
}

public class CountMenu
{
    private static ContextMenuExtension cme;

    public static void Attach()
    {
        cme = new ContextMenuExtension();

       
        MenuItem mi = new MenuItem("My Custom Menu Item");

       
        mi.Click += new EventHandler(OnMenuItemClick);
        cme.MenuItems.Add(mi);
       RXClass rxc = Entity.GetClass(typeof(Entity));
        Application.AddObjectContextMenuExtension(rxc, cme);
    }

    public static void Detach()
    { 
        RXClass rxc = Entity.GetClass(typeof(Entity));  
        Application.RemoveObjectContextMenuExtension(rxc, cme);
    }
    private static void OnMenuItemClick(object sender, EventArgs e)
    {
        Application.ShowAlertDialog("Custom menu item clicked!");
    }
}

Hi,

You should use AddDefaultContextMenuExtension instead of AddObjectContextMenuExtension.

[traiduong014969]

your code is working. Suppose i want to make both this:

+ Context Menu Without Object Selection
+ Context Menu With Object Selection

 Application.AddDefaultContextMenuExtension(cme);
 Application.AddObjectContextMenuExtension(rxc, cme);

I try like this. However It only works for case ''Context Menu Without Object Selection''
