Selected Nodes in TreeView

Question

there is a code snippet by Mahesh Chand located at; www.c-sharpcorner.com/Code/2004/Nov/TreeViewControl.asp which indicates that there is a SelectedNode property of the TreeView aps.net server control. i.e. void TreeView1_SelectedNodeChanged(object sender EventArgs e) { TextBox1.Text = TreeView1.SelectedNode.Text; TextBox2.Text = TreeView1.SelectedNode.NavigateUrl; } This is just what I need. However the version of the control (which I pulled off www.dot.net today) does not have this property. Rather there is only a SelectedNodeIndex which is a string along the lines of 0.1.1 indicating nominally where you happen to be in the tree. So any idea how I might resolve this. Many thanks in advance... Brian C.

Cut and paste this routine. It will give you the id and text of a node in a string delimited by a |. private string ucTreeView_GetNewNodeIdAndText(TreeViewSelectEventArgs e) { Microsoft.Web.UI.WebControls.TreeNode node = null; string delimStr = .; char [] delimiter = delimStr.ToCharArray(); string [] split = null; split = e.NewNode.Split(delimiter 100); foreach (string s in split) { if(node == null) node = ucTreeView.Nodes[int.Parse(s)]; else node = node.Nodes[int.Parse(s)]; } return node.ID + | + node.Text; }
