custom list box control

Hi everyone

I have user control derived from Windows.Forms.ListBox. How can I control
the type of items that user loads into it? In other words, how can I force
user to load only items of particular type? I guess, I need a control over
Items.Add method but I am not sure I can override Items collection.
Any ideas?

Thank you
