WPF: ComboBox TextSearch, how does it work?

Question

Am I correct in assuming that Textsearch in a combobox gives me a text input box at the top of the Combobox that filters out when I type in?

If so I do not understand why it's not working. I got a combobox with it's itemssource bound to a ListCollectionView through the DataContext. I the set IsTextSearchEnabled to true and set TextSearch.TextPath to a property of the object type in the ListCollectionView

 <ComboBox ItemsSource="{Binding Path=PersonCollection}"
           TextSearch.TextPath="Name"   DisplayMemberPath="Name" IsTextSearchEnabled="True" >
                    </ComboBox>

However I never get any inputbox.

The property defo works as that is displayed as I did set in DisplayMemberPath.

Am I assuming wrong and if so how does text search work?

Solution

You have to set IsEditable true.

I had seen alot of examples but never noticed IsEditable being set. It works, thank you.
