Anyone who has worked with the native WPF TreeView knows that its API is difficult to use (compared to the WinForms TreeView) and the performance isn't very good when binding to large large data sets.

We have started developing a completely custom implementation of a TreeView control that isn't based on the native TreeView control.  We'd love to get your input now during our design and prototyping phase on the following items:

• What are the top 5 built-in features you would like to see implemented in a TreeView?
• What specific pain points have you encountered with the native WPF TreeView?
• What features/API would help resolve those pain points?
• Any other features/functionality you think we should consider?

Please either write our support address with your feedback or join our Slack discussion on the topic and chat right with us.  The benefit of the chat option is that you can see what others are saying and throw in your two cents as well.
