I have a form that has 2 comboboxes. The first combobox (cb_CharacterName) which contains the character/user name and is loaded when the form opens, this works fine.
When a name is choosen in the cb_CharacterName the other combobox (Talent_Name) checks the (cb_CharacterName) combobox for the name and loads the talents the character/user has, this is also works fine.
However when a new character/user has been choosen in the cb_CharacterName the Talent_Name combobox does not remove the talents from the previous character, and just adds more to the list. At the same time if i select the same character twice i get duplicates.

How can i make the Talent_Name combobox each time a new character/user or the samme has been choosen to flush the old informations and add the new ones in? i presume this would also remove the duplications problem.
Also, does WPF have a SelectedIndex? right now i am using DropdownClosed which is not the perfect choice, since when i use the arrows in the keyboard the values the character/user contains does not gets updated.
