C# treeview node

Question

I have a treeview1:

             treenode--
                  treenode1--
                     treenode2
                     treenode3

You can select only node2 and node3 if you want to display them parameters. How can i block selecting node and node1? I try like that,but than you can select all nodes:

    private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
    {
    ...
     }

Answer 1

you will have to use SelectAction Property on the tree node. you will need to set it on the node when you are creating them.

set selectaction=none on node and node1
