Introduction

This is a custom paging control for data controls (GridView / DataList / Repeater). From this control, developers can easily add custom paging on a data control.

Using the code

It is very simple to add custom paging on a data control. Please add the DLL (App_Web_pagingcontrol.ascx.cdcab7d2.dll) in the bin directory and PagingControl.ascx in the root directory.

Here is the ASPX code:

ASP.NET

<%@ Page Language="C#" AutoEventWireup="true" 
    CodeFile="Default.aspx.cs" Inherits="GridView_Default" %>

<%@ Register Src="PagingControl.ascx" 
   TagName="PagingControl" TagPrefix="uc1" %>
