C# replacement for standard Treeview ?

Question

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

• Multiple selection of items
• Better performance (performance of standard widget is simply awful, in particular when adding a long list of items)
• Scrolling while drag and dropping an item inside the treeview widget

I may be forgetting some, but these are quite important. Since i already have a software that makes use of the standard Treeview, I will take in consideration API differences.

Answer 1

How about this?

Answer 2

As an open source alternative, TreeViewAdv is very good.

Answer 3

You can check the IntegralUI TreeView control from Lidor Systems. There are:

1. Four types of selection modes: None, One, MultiSimple and MultiExtended
2. Fast loading of large set of nodes. Even option to show custom progress during loading.
3. Advanced drag&drop support with option to choose from predefined or create a custom operation. The scrolling during drag&drop is also included.
