Hi,

you can get the list of child node using the below code

            List<string> lstProgramming = new List<string>();
            for (int intIndex = 0; intIndex < TreeView1.SelectedNode.ChildNodes.Count; intIndex++)
            {
                lstProgramming.Add(TreeView1.SelectedNode.ChildNodes[intIndex].Text);
            }

Thanks a lot,

It's work but in this code if i select Programming it's return first level childs (Web,Application), but i want return all level childs (Web,asp,php,application,c#,Java,...)

Hi Mostafa,

Here is the recursive method, I hope this will helpful for you.

protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e)
{
    List<string> lstProgramming = new List<string>();
    for (int intIndex = 0; intIndex < TreeView1.SelectedNode.ChildNodes.Count; intIndex++)
    {
        lstProgramming.Add(TreeView1.SelectedNode.ChildNodes[intIndex].Text);
        RecursiveCall(TreeView1.SelectedNode.ChildNodes[intIndex], ref lstProgramming);
    }
}
private void RecursiveCall(TreeNode treeNode, ref List<string> lstProgramming)
{ // Print each node recursively.
    for (int intIndex = 0; intIndex < treeNode.ChildNodes.Count; intIndex++)
    {
        lstProgramming.Add(treeNode.ChildNodes[intIndex].Text);
    }
}
