Paging using AJAX

Introduction

This will help you with very fast paging navigation and you can also customize rows per page.

Background

WebMethod and AJAX

Note: After downloading the demo, you have to run database script & then make change of ConnectionString in Web.config file.

Using the Code

This demo gets data with WebMethod and transfers to client side in JSON so there is no page reload. That's why it's faster and you can also customize design as per your requirement.

JavaScript Code Syntax

$.ajax({
        type: "POST", //To hide in Javascript URL
        url: "Filename.aspx/FunctionName", //WebMethod URL & Function Name
        data: '{Data You want to pass}', //Data to Transfer to WebMethod
        contentType: "application/json;charset=utf-8",
        dataType: "json",
        success: function (data) {
            //Code for Success
        },
        error: function (result) {
       //Error Message
        }
    }); 

jQuery File to be Used in this Demo

<script src="Script/jquery-2.1.1.min.js" 
    type="text/javascript"></script>

HTML Code

<asp:HiddenField ID="hdnStartingIndex" 
    ClientIDMode="Static" runat="server" />
<asp:HiddenField ID="hdnEndingIndex" 
ClientIDMode="Static" runat="server" />
<asp:HiddenField ID="hdnCurrentPage" 
ClientIDMode="Static" runat="server" />
<asp:HiddenField ID="hdnLastPage" 
ClientIDMode="Static" runat="server" />
<div id="divAllUsers" style="background: #f3f3f3;">
</div> 

Stored Procedure In this Demo

CREATE PROCEDURE [dbo].[sp_User]
    @operation int=0,
    @StartIndex int=0,
    @PageSize int=0,
    @NumberOfPage int=0,
    @NumberOfPageModulo int=0,
    @TotalRecords int=0
AS
BEGIN
    IF(@operation=1)
        BEGIN
            select @NumberOfPage= count(*)/@PageSize,@NumberOfPageModulo= _
            count(*)%@PageSize,@TotalRecords= count(*) from tbl_User

            if(@NumberOfPageModulo>0)
            set @NumberOfPage += 1


            ;with samp as(
                select ROW_NUMBER() OVER (ORDER BY User_id ASC) AS CountData,* from tbl_User
                )
                select *,@NumberOfPage as NumberOfPage,@TotalRecords as TotalRecords _
                from samp where CountData between @StartIndex and _
                ((@StartIndex-1)+@PageSize) ORDER BY CountData
        END
END

            Users dataServices = new Users();

            DataTable dtAllUserData = new DataTable();

            dtAllUserData = dataServices.GetAllUser(StartIndex, PageSize);

            if (dtAllUserData != null)
            {
                foreach (DataRow dtRow in dtAllUserData.Rows)
                {
                    AllUsers SetData = new AllUsers();

                    SetData.User_id = Convert.ToInt32(dtRow["User_id"]);
                    SetData.Name = Convert.ToString(dtRow["Name"]);
                    SetData.City = Convert.ToString(dtRow["City"]);
                    SetData.email = Convert.ToString(dtRow["email"]);
                    SetData.CountData = Convert.ToInt32(dtRow["CountData"]);
                    SetData.TotalRecords = Convert.ToInt32(dtRow["TotalRecords"]);
                    SetData.NumberOfPage = Convert.ToInt32(dtRow["NumberOfPage"]);

                    Details.Add(SetData);
                }
            }
