WPF C＃Treeview，包含来自数据库的动态列表

I want to use a treeview to show a Question and an Answer. It will pull a list of questions to be answered and if they have been answered in the past it will show the answer to that question. Each answer will either be a list in a combobox or straight text. I need it to pull the correct template for the answer. I have stored in the database an id of which one of the templates that the answer should pull. I have never used this before so I am not sure how. If there is a better way I am all for it too.I want to use a treeview to show a Question and
