C # replacement for standard Treeview?

Question

I would like to find a replacement for System.Windows.Form.Treeview. I need the following improvements:

• Multiple selection of items
• Better performance (the performance of a standard widget is just awful, especially when adding a long list of items)
• Scrolling while dragging an item inside a treeview widget

I may forget some, but it is very important. Since I already have software using the standard Treeview, I will take into account the differences in the API.

Answer 1

As an open source alternative, TreeViewAdv is very good.

Answer 2

this?

Answer 3

ObjectListView - .
