    Hello every body,,

    I’m new to jqwidgets, and spent last few dayes trying to make jqxGrid working with no reasons,, The Gride is loading with headers but with no data,, Can any one look if i’m right..

    I’m using asp.net to load data form sqlserver table and convert it to xml as below:

    1)) ASP.NET 

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Script.Services;
using System.Data;
using System.Configuration;
using System.Web.Script.Serialization;
using System.Web.Services;

namespace WebApplication1
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        
        protected void Page_Load(object sender, EventArgs e)
        {
            
        }

        [WebMethod]
        [ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Xml)]
        public static string getTenders()
        {
            conn cn = new conn();
            DataSet dsRetTendExpire = cn.getData("select Enq_ID,Enq_Ref from Enquiry", "Enquiry");
            System.IO.StringWriter writer = new System.IO.StringWriter();
            dsRetTendExpire.Tables[0].WriteXml(writer, XmlWriteMode.WriteSchema, false);
            return writer.ToString();
        }
    }
}

    2)) Jquery and HTML Code:

    <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.WebForm1" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <link href="jqwidgets/styles/jqx.base.css" rel="stylesheet" />
    <link href="jqwidgets/styles/jqx.classic.css" rel="stylesheet" />
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
    <script src="jqwidgets/jqxcore.js"></script>
    <script src="jqwidgets/jqxbuttons.js"></script>
    <script src="jqwidgets/jqxdata.js"></script>
    <script src="jqwidgets/jqxgrid.js"></script>
    <script src="jqwidgets/jqxgrid.selection.js"></script>
    <script src="jqwidgets/jqxmenu.js"></script>
    <script src="jqwidgets/jqxscrollbar.js"></script>

    <script type="text/javascript">

        $(document).ready(function () {
            var url = "WebForm1.aspx/getTenders";
            var source = {
                datatype: "xml",
                datafields: [
                { name: 'Enq_ID' },
                { name: 'Enq_Ref' }
                ],
                async: false,
                record: 'Table',
                url: url
            };

            var dataAdapter = new $.jqx.dataAdapter(source,
                { contentType: 'application/json; charset=utf-8' }
            );

            $("#jqxgrid").jqxGrid({
                source: dataAdapter,
                theme: 'classic',
                width: 850,
                columns: [
                    { text: 'Enquery ID', dataField: 'Enq_ID', width: 250 },
                    { text: 'Refrance', dataField: 'Enq_Ref', width: 300 }
                ]
            });
        });
    </script>
</head>
<body>
    <form id="form1" runat="server">
    
        <div id="jqxgrid"></div>
  
    </form>
</body>
</html>

    Hello emad,

    Your client-side code seems correct. The issue may be in retrieving the data. Please check out the ASP .NET Integration tutorials in the Documentation to see how to correctly bind jqxGrid to a database.

    To see if the data is successfully loaded in the data adapter, set its loadComplete callback function, e.g.:

    var dataAdapter = new $.jqx.dataAdapter(source, {
    contentType: 'application/json; charset=utf-8',
    loadComplete: function() {
        alert("Data loaded successfully.");
    }
});

    Best Regards,
    Dimitar

    Hi emad,

    It is possible that your XML mapping is incorrect and the loaded data is not the intended one. We cannot be sure without some sample data.
