I ran into some problems using jQuery to read an external xml file and build a tree. To get around it, I am working on C# code to read the external xml file and present the data to the jQuery. Here is my code so far:

I would like to read the external xml file and print it out as is. Can someone help me how to print the xml file as is?

Can someone help with how do I read this jstree.xml and present it to the jQuery. In jQuery, I should be able to do this:

$(document).ready(function () {
    $("#div").jstree({
        "xml_data": {
            "ajax": { 
                "url": "jstree.xml"

    Jquery should request to ASP.NET Page, like “jstree.aspx”, this page, jstree.aspx, should return a XML Stream.

    In your ASPX, after the code you writed:

        Response.Clear();
    Response.ContentType = "text/xml";
    Response.Charset = "utf-8";

    XmlWriterSettings settings = new XmlWriterSettings();
    settings.Encoding = Encoding.UTF8;
    settings.Indent = true;
    using (XmlWriter writer = XmlWriter.Create(Request.OutputStream, settings))
    { 
       //Write here
    }
