You have to eliminate the duplicates by yourself when setting the ItemsSource.

Something like myComboBox.ItemsSource = myItemsSource.Distinct();  which will use the default equality comparer to compare values.

If you need to define your own equality comparer, you can use this distinct overload : http://msdn.microsoft.com/en-us/library/bb338049(v=vs.95).aspx
