c# - Tree View of a Data Grid -

I am trying to apply some trees to ASP.NET:

However, One is the Tree View Component in the Navigation tab I want a datagroup in a tree view that is not navigation. Is there a ready free component ?? If not, what is the right ingredient to start with making such a component of a tree?

I am not in haste, it would be better for me if I can build my own, but what component do I want to start with? Is this datagrid? The fact is that this tool appears in the navigation tab in the box - You

Asp: treeview & gt; There is nothing else to stop using that which is another hierarchical structure that represents the data that has been used for data as well as for navigation.
