- B1: Download CSDL Northwind tại đây và thực hiện công việc Restore Data.

- B2: Tạo Project trong Microsoft Visual Studio 2010

Trong Visual Studio tạo 1 Class có tên: Utility và nhập đoạn Code phía dưới cho Class này.

C# Code

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Data.SqlClient;

using System.Data;

using System.Configuration;

namespace CustomPaginationofDataTables

{

public class SqlDataProvider

{

#region "Membres Prives"

private string _connectionString;

#endregion

#region "Constructeurs"

public SqlDataProvider()

{

try

{

_connectionString = ConfigurationManager.ConnectionStrings["SiteSqlServer"].ConnectionString;

}

catch

{

}

#endregion

#region "Proprietes"

public string ConnectionString

{

get { return _connectionString; }

}

#endregion

#region "Functions"

public DataTable FillTable(string sql)

{

try

{

DataTable tb = new DataTable();

SqlDataAdapter adap = new SqlDataAdapter(sql, _connectionString);

adap.Fill(tb);

return tb;

}

catch

{

return null;

}

#endregion

}

VB.NET Code

Imports System.Data.SqlClient

Imports System.Data

Namespace CustomPaginationofDataTables

Public Class SqlDataProvider

#Region "Membres Prives"

Shared _IsError As Boolean = False

Private _connectionString As String

#End Region

#Region "Constructeurs"

Public Sub New()

Try

_connectionString = ConfigurationManager.ConnectionStrings("SiteSqlServer").ConnectionString

_IsError = False

Catch ex As Exception

_IsError = True

End Try

End Sub

#End Region

#Region "Proprietes"

Public ReadOnly Property ConnectionString() As String

Get

Return _connectionString

End Get

End Property

#End Region

#Region "Functions"

Public Function FillTable(ByVal sql As String) As DataTable

Try

Dim tb As New DataTable

Dim adap As New SqlDataAdapter(sql, _connectionString)

adap.Fill(tb)

Return tb

Catch ex As Exception

Return Nothing

End Try

End Function

#End Region

End Class

End Namespace

- B3: Mở file Site.Master dạng HTML và bổ xung đoạn mã phía dưới trong thẻ Head

<title>Page Size and Scroller of DataTables in Asp.net</title>

<asp:ContentPlaceHolder ID="HeadContent" runat="server">

</asp:ContentPlaceHolder>

</head>

- B4: Mở file Default.aspx dưới dạng HTML và nhập mã HTML

<%@ Page Title="Custom Pagination of jQuery DataTables in Asp.net" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="CustomPaginationofDataTables._Default" %>

<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">

</asp:Content>

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<h3>Custom Pagination of jQuery DataTables in Asp.net</h3>

</div>

<asp:Repeater ID="dlObject" runat="server">

<thead>

<tr>

<th align="center">ProductName</th>

<th align="center">QuantityPerUnit</th>

<th align="center">UnitPrice</th>

<th align="center">UnitsInStock</th>

<th align="center">UnitsOnOrder</th>

</tr>

</thead>

<tbody>

</HeaderTemplate>

<tr>

</tr>

</ItemTemplate>

</tbody>

</table>

</FooterTemplate>

</asp:Repeater>

</div>

function pageLoad() {

$('#tblData').dataTable({

"sPaginationType": "full_numbers",

"oLanguage": {

"sInfo": "Showing _START_ to _END_/_TOTAL_",

"oPaginate": {

"sFirst": "<<", // This is the link to the first page

"sPrevious": "<", // This is the link to the previous page

"sNext": ">", // This is the link to the next page

"sLast": ">>" // This is the link to the last page

}

});

};

</script>

</asp:Content>

Hoặc bạn có thể sử dụng ảnh để làm các nút di chuyển trang.

Và thay đổi đoạn mã Javasript phía dưới

function pageLoad() {

$('#tblData').dataTable({

"sPaginationType": "full_numbers",

"oLanguage": {

"sInfo": "Showing _START_ to _END_/_TOTAL_",

"oPaginate": {

"sFirst": '<img src="Images/First.gif" width="18" height="18" />', // This is the link to the first page

"sPrevious": '<img src="Images/Prev.gif" width="18" height="18" />', // This is the link to the previous page

"sNext": '<img src="Images/Next.gif" width="18" height="18" />', // This is the link to the next page

"sLast": '<img src="Images/Last.gif" width="18" height="18" />' // This is the link to the last page

}

});

};

</script>
