object -> treeview -> selected object in my object

Ok here is my question:

f.ex I have data structure something like this:

String name
  - List<String> subNames;
        - List<String> subSubNames;

I can easily populate tree view with the data. But how I should get vise versa stuff on this.

for example: I select some subSubName in the treeview, what is the easiest way to get Name, but not in the treeview it self but my own object.

I can code it by myself, but maybe there is an easiest way of doing that? Something like bind object to the treeview etc...

You can use the Tag property of TreeNode to store data about the node.

An example where variable name contains your data and treeView1 is your TreeView:

TreeNode node = new TreeNode();
node.Text = name.ToString(); //can be any string
node.Tag = name;
treeView1.Nodes.Add(node);

To retrieve the data from a node, just cast the Tag to the right class:

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
    name = (Name)e.Node.Tag;
}
