Getting exact datapath of a treeview node

Question

I am binding a Treeview to an XMLDataSource, The databindings are being generated automaticaly, The XML looks like this:-
<pre>
<Passengers>
<Passenger type="normal" ethnic="asian">
<PassengerName>Name1</PassengerName>
</Passenger>
<Passenger type="normal">
<PassengerName>Name2</PassengerName>
</Passenger>
<Passenger>
<PassengerName>Name3</PassengerName>
</Passenger>
</Passengers>
</pre>

The Treeview displays the XML correctly but when i click on a node and the SelectedNodeChanged event fires the SelectedNode.DataPath is always the path to the first passenger in the list no matter which passenger node i click on.

Does anyone know how to get the datapath of the actual node i click on ?

Couldn't you use the value property of the TreeNode to store the index of each node? You can then track it down using this value.

Good luck!

Didn't get you exactly..

Below is my code:

XmlDocument objDoc = new XmlDocument();
objDoc.Load(Server.MapPath("AngloMap.xml"));
if (!string.IsNullOrEmpty(TreeView2.SelectedNode.DataPath))
{
XmlNode node = objDoc.SelectSingleNode(TreeView2.SelectedNode.DataPath);
txtEditXML.Text = node.InnerXml;
Session["CurrentEditXpath"] = TreeView2.SelectedNode.DataPath;
}

After loading the xml you could add an index to each node. passenger with name1 would have value 1 and passenger with name2 value 2 and so on. If you then click on the node you can read the index of the node from the value property.
