    TableData is a DataTable

     using (var sda = new SqlDataAdapter())  
                       cmd.Connection = con;  
                       sda.SelectCommand = cmd;

    in the sample using an ajax for display data into a table

    function getDetails() {  
            type: "POST",  
            contentType: "application/json; charset=utf-8",  
            url: "Default.aspx/GetData", //Default.aspx is page and GetData is the WebMethod  
            data: {},  
            dataType: "json",  
            success: function(data) {  
                $('#dataTables-example tbody').remove(); // Every time I am removing the body of Table and applying loop to display data  
                for (var i = 0; i < data.d.length; i++) {  
                        "<tr><td>" + data.d[i].FName + "</td><td>" + data.d[i].Email + "</td>" +  
                        "<td>" + data.d[i].HomeMobile + "</td>" + "<td>" + data.d[i].OfficeMobile + "</td>" +  
                        "<td>" + data.d[i].Doj + "</td>" + "<td>" + data.d[i].Dob + "</td>" +  
                        "<td>" + "<input type='button' class='btn btn-primary editButton' data-id='" + data.d[i].EmpId + "' data-toggle='modal' data-target='#myModal' name='submitButton' id='btnEdit' value='Edit' />" + "</td>" +  
                        "<td><input type='button' class='btn btn-primary' name='submitButton' id='btnDelete' value='Delete'/> </td></tr>");  
            error: function() {  
                alert("Error while Showing update data");  

    and the <g class="gr_ gr_126 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar multiReplace" id="126" data-gr-id="126">highlight</g> line fetch data from code behind

       public static Employee[] GetData() //Show the details of the data after insert in HTML Table  
           var details = new List<Employee>();  
           using (var con = new SqlConnection(Constr))  
               const string query = "select * from TblUser order by EmpId desc";  
               using (var cmd = new SqlCommand(query, con))  
                   using (var sda = new SqlDataAdapter())  
                       cmd.Connection = con;  
                       sda.SelectCommand = cmd;  
                       details.AddRange(from DataRow dtrow in TableData.Rows  
                           select new Employee  
                               EmpId = Convert.ToInt32(dtrow["EmpId"]),  
                               FName = dtrow["Fname"].ToString(),  
                               Email = dtrow["EMail"].ToString(),  
                               HomeMobile = dtrow["Telephone"].ToString(),

    Hi JagjitSingh ,

    When the error  Uncaught TypeError: Cannot read property 'length' of undefined  occurs ,it’s normally caused by your variable data doesn’t have a property named “d”.

    You could use  F12 developer tool to help you check your data or  use console.log(data) to get more information.

    Press F12  , click the  “Sources” item  and click your aspx page.
    Click the number at left to decide which line you want to  put your breakpoint.
    Press F5 to reload the page , the  code will stop  where you put your breakpoint.

    You could add another breakpoint. press F8 to skip to the next breakpoint , F10 to go to the next line.
    Move your cursor to your data variable , it will show you detailed information .

    Please check if data has a property named ‘d’.
    Best regards ,
