HI,

I have ajax code for populate the datas dynamically with html tags.

$.ajax(
               {
                   type: "POST",
                   url: "../../GeneralService.asmx/Get_Bill_Desk_Items",
                   dataType: "json",
                   data: {},
                   contentType: "application/json; charset=utf-8",
                   success: function (json) {

                       var xmlDoc = "";
                       var xml = "";
                       xmlDoc = $.parseXML(json.d);
                       xml = $(xmlDoc);

                       document.getElementById("PopulateBillDeskItems").innerHTML = "";

                       $(xml).find("Table").each(function () {
                           var Category = $(this).find("Category").text();
                           var Table_Room_Code = $(this).find("Table_Room_Code").text();
                           var Table_Room_No = $(this).find("Table_Room_No").text();
                           var Item_Total = $(this).find("Item_Total").text();

                           $("#PopulateBillDeskItems").append(" <tr class='gradeX'><td>" + Category + "</td><td>" + Table_Room_Code + "</td><td>" + Table_Room_No + "</td><td class='center'>" + Item_Total + "</td></tr>");

                       });
                   }
                       });

And in the HTML Page :

<table id="table-example" class="table">
		   <thead>
		      <tr>
			<th>Category</th>
			<th>Table-Room Code</th>
			<th>Table-Room NO</th>
			<th>Total AMT</th>
		      </tr>
		   </thead>

		  <tbody id ="PopulateBillDeskItems"></tbody>

	      </table>

This code is working fine... But When i go to the page source the HTML code is not populated.but the design side i can see the changes.

And what is my need is,

I have a javascript css Table, And in that table i have populated the datas dynamically using the above code.

And in that table there is search and sort option.
But when i populate datas dynamically using the above code, The search and sort option is not working.

But when i hard-code the datas to that table then the search and sort option is working fine.

Please help me...

Thanks
Dileep..
