Hi Alex, I see what you mean; the problem is that the ThemedLinkMenu is marked Read-Only when inherited if the Collection contains any items. That's probably by design, although you can get around it by adding the initial selections in code in the base form's constructor:
{ InitializeComponent();
ThemedLinkMenuItem themedLinkMenuItem1 = new ThemedLinkMenuItem();
themedLinkMenuItem1.Key = "Exit";
themedLinkMenuItem1.Title = "Exit";
themedLinkMenu1.ItemCollection.Add( themedLinkMenuItem1 );
But your event handler in the forms that derive from it need to handle the default ("Exit" in this case). I also noticed that removing a ThemedLinkMenuItem in the base form's Items Collection doesn't visually clear it from the ThemedLinkMenu. I'm sure Trent has thoughts on the matter.
