usually the treeview is populated from an xml document or database source. I would start at the source of the data and convert this into xml.

if you need to pull data from the GUI control (requires user input?) then loop through the control, extract the values you want and place them in an XMLDocument object. Save the XMLDocument.

Thanks jmeckley,

I am adding or populatin the Treeview from the GUI

Can you write a sample code for creating XML Node and Child Nodes... using XMLDocument and XMLNode etc (with Attributes)

is this a windows or web control?
what does the tree data look like?
what do you want the xml file to look like?

its a window control... I want to save it an xml File
For Eg:
TreeView
Root
- ----- ChildNode
- ChildNode1
- ----- ChildNode3
- ChildNode4

XML
<Root>
<ChildNode><ChildNode1/></ChildNode>
<ChildNode3><ChildNode4/><ChildNode3>
</Root>

I am not fimiliar with the exact properties of the Desktop TreeView control, but it would look something like this:

private XMLDocument xDoc = null;
protected void [MyEvent](object sender, EventArgs e)
{
   if(xDoc == null)
   {
      this.xDoc = new XMLDocument();
      this.xDoc.LoadXML("<Root/>");
      xDoc.AppendChild(AppendTreeViewNode(this.myTreeView.TopNode));
      xDoc.Save("filename.xml");
   }
}

private XmlNode AppendTreeViewNode(TreeViewNode treeNode)
{
    XmlNode toReturn = this.xDoc.CreateNode(NodeType.Element);
    XmlAttribute text = this.xDoc.CreateNode(NodeType.Attribute);
    XmlAttribute value = this.xDoc.CreateNode(NodeType.Attribute);

    text.Name = "DisplayText";
    text.Value = treeNode.Text;

    value.Name = "Value";
    value.Value = treeNode.Value;

    toReturn.Attributes.Add(text);
    toReturn.Attributes.Add(value);

    foreach(TreeViewNode child in treeNode.Children)
    {
         toReturn.AppendChild(AppendTreeViewNode(child));
    }

    return toReturn;
}
