Der folgende Code ist zum Aufbau eines eigenen Textbox-Kombinations-Elementes, mit welchem man Texte auswählen kann oder manuell eingeben kann

Man muss nur im Projekt einen Unterverzeichnis Usercontrols erstellen, ein neues Usercontrol erstellen und den folgenden Code dort einfügen.

 

XAML Code

 

Im Usercontrol befindet sich nur ein Textbox Element und ein Dropdown Element.
