I use the autocompletebox, which have a list of country as ItemsSource. From this autocompletebox, I would have the possibility to add a new country, which is not in the current list. To do that, I want to have a custom item in the filtered list, which do something special and is selectable as an other item of the list.
I have the idea to add a special item in the ItemsSource and change the template of this special item with a TemplateSelector, but I would like to know if it exists a best way to do that?
I have attached a picture to illustrate what I would like to do.
Thanks for your help!
