WPF Combobox: Different template in textbox and drop-downlist

Question

This is my combo-box.

Answer 1

Unfortunately, the SelectionBoxItemTemplate is a readonly property, so we have to do a bit more work. By doing the ItemTemplate to be how you want the item to appear when selected, you can edit the ItemContainerStyle to provide a ControlTemplate that includes the other fields you want to display.

For the ComboBoxItem template, I just modified the default one, so it should be fully functional.
