tanks for you

Using plain treeview you can't but have a look at for example these:
- .NET Multi-Select TreeView
- Multiselect Treeview Implementation[^]
- Multi-Select TreeView Control in C#[^]

Interesting, my 5.
By the way, do you know such thing as virtual tree view, for WPF or Forms, whatever, much like Delphi 3rd-party one?
There are some obvious solutions when building of the tree is deferred until a node is expanded, but that's not it. The real thing only holds data of the nodes currently on screen, plus one-two screens cashed...

Thanks, don't know about Delphi solutions, and in .Net environment I havent used virtual tree views at all. In all my projects we have used/built virtual grid views to be able to show sctructurized data and master detail information in-place. These solutions have used caching and deferred layout update in order to improve display performance. However, lately these have been available in 3rd party libraries such as DevExpress or Infragistics so it haven't been necessary to build them from scratch anymore (although it's fun) :)
This link[^] might help you.
