is it possible to subclass ElegantRibbon controls?

MSDN (cit.): All the parts [of a class] must use the partial keyword.

Do you declare ER classes as partial?

If so, I would like to globally override PopupMenu.OnShowing - can you explain how to do it, please?

Okay, this is my mistake, I should derieve from PopupMenu and then override

Anyway, is there any way to add some custom global behaviour to buttons’ PopupMenus?

I’d like to disable some PopupMenu’ items depending on some specific conditions, like user name.

You can enable/disable any of the controls in the popup menu using the Enabled property of the base class. For instance:

Elegant.Ui.PopupMenu popupMenu1 = new Elegant.Ui.PopupMenu();
Elegant.Ui.Button button1 = new Elegant.Ui.Button();
button1.Text = "Some text";
Then you can switch the enabled/disabled button state somewhere in your code in the following way:
button1.Enabled = false;
