I have a WPF CombBox as follows:

<ComboBox 
   ItemsSource="{Binding Source={StaticResource myList}}"
   SelectedItem="{Binding Path=mySelectedItem}"
/>

The problem I have is that when the bound value changes, the selected value in the combobox's textbox does not update. (Note - the values in the combobox list do update).

I am using MVVM so I can detect in the view model when the binding changes and call a property changed event and this is updating the combobox, but not the value displayed within the textbox.

I think this could be done in the template of the combobox - somehow make the textbox be bound to the selecteditem of the combobox, or always update when it updates?

I don't know how to do this though so any advice would be most appreciated.
