Anybody can shart some working samples of using that control on Windows
form?

Thanks
 
I think MSDN Library should have some. If you are experiencing particular
problems with TreeView, please post them here, or, even better, in the
microsoft.public.dotnet.framework.windowsforms newsgroup.
 
No I dont experience any PARTICULAR problem.
I am experiencing PROBLEM to get started in .NET.
Usually samples are very helpful.

I see your point, Mark. Then MSDN examples are a good point to start, as
well as GotDotNet QuickStart tutorials (found at http://www.gotdotnet.com).

You can also look at the .NET 247 portal (http://www.dotnet247.com if I am
not mistaken).

Thanks for help.
Would it be better idea to use third party component for
TreeView? The component that already has (or almost)
functionality I need?

The following Method fills a TreeView with the DataSet (and its Tables)
Strucure.
You mut call the Method with a reference to your exsisting TreeView
Control, DataSet to use and a String Array with Branch/Node Strings to use.
In my Projects these Strings are Language dependent and must be filled
beforhand.

OnFillTreeViewDataSet(ref TreeViewDataSet, ref dset_MainFrame, ref
sa_TreeViewDataSet);

Hope this helps as a starter.
