AnnAutomationObject ContextMenu does not work correctly

I create my automation objects manually and I want to have to objects of the same type for example two AnnNoteObject tools. For one of them I want to display the context menu (after right click) so I create it as follows:

noteObj.ContextMenu = manager.CreateDefaultObjectContextMenu(noteObj.Id);

But for the second note object I don't want to display the context menu so I set it to null.

Unfortunatelly the result is that the context menu is always displayed for both object. If I change the objects creation order (for first object context menu is set to null) then the context menu is not displayed for both objects. Of course I create the AnnAutomationObject with different identifiers.

You can supply your own derived class to the
ContextMenu property, and in this class examine which object was being clicked and decide whether to display the menu or not.

Could you provide me some example code? Where should I examine (what event) whether the context menu should be displayed or nor?

In my opinion if I set the default menu for a first note object and null for the second note object then the context menu should appear only for first object not for both.

You can implement a PopUp event handler for the
ContextMenu class, and in this event examine which object was being clicked and decide whether to display the menu or not.

I have attached to this post the file "Mianform.cs"
for the "C# annotation automation demo", in which I modified the code
to hide context menu from popping up for any Note object whose text is
"A". To find my modifications search for the word "NoteMenu".
