If you dont want to add all nodes of treeview then modify DisplayChildNodeText method as void DisplayChildNodeText(TreeNode node) { //add nodes to comboBox comboBox1.Items.Add(node.Text); } it will take only parent nodes to comboBox.

Hi  Try this code .. it will add all nodes of treeview to comboBox as a item. public Form() { InitializeComponent(); if (LinksTreeView.Nodes.Count > 0) { // Iterate through the root nodes in the Nodes property. for (int i = 0; i { // Display the nodes. DisplayChildNodeText(LinksTreeView.Nodes[i]); } } else { MessageBox.Show(The TreeView control does not have any nodes.); } } void DisplayChildNodeText(TreeNode node) { //add nodes to comboBox comboBox1.Items.Add(node.Text); for (int i = 0; i { // Recursively call the DisplayChildNodeText method to // traverse the tree and display all the child nodes. DisplayChildNodeText(node.Nodes[i]); } }
