        private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
        {
            var nodes = treeView1.Nodes;
            comboBox1.DisplayMember = "Text";
            comboBox1.DataSource = nodes;
        }

        private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            var node = comboBox1.SelectedItem as TreeNode;
            if (node == null)
                return;

            treeView1.SelectedNode = node;
        }

that code only get root node. and Combobox only show root node text not any other comboBox value

winform

            treeNode1.Text = "Node2";
            treeNode2.Name = "Node1";
            treeNode2.Text = "Node1";

            treeNode3.Text = "Node1";
            treeNode4.Name = "Node0";
