调用遍历的方法
protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e)
{
string s = TreeView1.SelectedValue.ToString();
Label1.Text = s;
string ss = string.Empty;
Label2.Text = judge(ss);
}
string judge(string ss )
{
foreach (TreeNode n in this.TreeView1.Nodes)
{
if (n.ChildNodes.Count > 0)
{
foreach (TreeNode t in n.ChildNodes)
{
if (t.Selected) { return n.Text; }
}
}
}
return string .Empty ;
}
