TreePanel + Xml Web Services On Demand (Example)

[swemaniac]

Look, this is something I've been trying to figure out for some time and I just found a way to make extjs treepanel to load nodes on-demand directly from an asp.net xml web service (that's xml, not json, json + web services ehh kinda iffy). I just thought I'd share it with anyone else who wants this to work. You need XmlTreeLoader.js from the examples.

Web service:

[WebMethod]
[ScriptMethod]
public XmlNode GetNodes(int node)
{
    //get nodes from db etc
    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<nodes><node id=\"2\" text=\"the node\" expanded=\"false\"/><node id=\"3\" text=\"another node\" expanded=\"false\"/></nodes>");
    return doc.ChildNodes[0];
}

Script:

//....
treeView = new Ext.tree.TreePanel({
            loader: new Ext.ux.XmlTreeLoader({dataUrl:'Service.asmx/GetNodes'})
        });
// other attrs...

Sorry if this isn't something new..

Nice example, but is no working to me.
Can you send a extended example, because the treeview is not loading data.

Thank's a lot for your help!
