Jquery DataTables
More details
First we need to download the required files for jquery datatables form their website.
I have 2 cases:
Case1:
when bServerSide = false and jquery datatable gets the whole data
in this case, I need to fetch the whole data and populate the HTML table with proper format (THEAD, TBODY, ...).
Person.cs
using System; using System.Collections.Generic; public class Person { public int Id { get; set; } public string Name { get; set; } public static ICollection<Person> GetPersons() { IList<Person> list = new List<Person>(); for (int i = 0; i < 63; i++) { list.Add(new Person() { Id = i, Name = "name" + i }); } return list; } }

test1.aspx.cs
public partial class jqueryDataTable_test1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { repeater.DataSource = Person.GetPersons(); repeater.DataBind(); } }
Case2:
when bServerSide = true and jquery datatable gets the data from server side on demand and it has insert and update and delete features. and I am using $.ajax to call page methods and can be easily replaced with calling asmx or wcf methods or ashx handler.

These are the most clear and complete examples I've seen for using DataTables with Asp.Net. Thanks a lot!
Ok you claim it will work with WCF I say it won't, prove me wrong
thanks mate, check this out:

ASP.net and Java have been the most successful languages in the 4th generation languages that have evolved over the years.

In this post data tables in ASP.Net described. Jquery is interesting topic. The code is simple so you can try to implement it. This post is very useful. I got idea how to implement jquery in my application. Thanks. Great work guys!

MAN! You are absolutely the best human alive. You have any idea how many days I wasted trying to get databales to read data from my SQL Server database? Too many! I wish I would have found this sooner. Worked so well I feel stupid now that the solution turned out to be something so simple. Great stuff.
Man.... You are hero! thanks a lot for this nice, clean and wonderful simple written Demo with source code.
You are the best. thanks
You save my programming life.
Thank you very much to this article :).
