This is the all code. Very simple and short. I need to
populate a treeView in aspx page (web form) from XML file.
I get en completion error:No overload for
method 'TreeNode' takes '1' arguments .
using System;
using System.Web.UI.WebControls;
using Microsoft.Web.UI.WebControls;
using System.Xml;
namespace PopulateTVTest
{
/// <summary>
/// Summary description for WebForm1.

{
protected Microsoft.Web.UI.WebControls.TreeView treeView1;
protected System.Web.UI.WebControls.Button Button1;
private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
}
#region Web Form Designer generated code
override protected void OnInit(EventArgs e)
{
//

Designer.

InitializeComponent();
base.OnInit(e);
}

}

e)
{

treeView1.Nodes.Add(new TreeNode

private void AddNode(XmlNode inXmlNode, TreeNode
inTreeNode)
{
XmlNode xNode;
TreeNode tNode;
XmlNodeList nodeList;
int i;
// Loop through the XML nodes until the leaf is reached.
// Add the nodes to the TreeView during the looping
process.
if (inXmlNode.HasChildNodes)
{
nodeList = inXmlNode.ChildNodes;
for(i = 0; i<=nodeList.Count - 1; i++)
{

else

thank you very much!
