Custom Paging using AJAX with Sorting

• Download source - 180 KB

Introduction

This will help you with very fast paging navigation and you can also customize rows per page and in this version, sorting in all columns is also included.

Paging and sorting all functions works in single function or single WebMethod.

Background

WebMethod and AJAX

Note

1. After downloading the demo, you have to run database script (File: Mydb_Script v2.0.sql) & then make change of ConnectionString inWeb.config file.
2. It has change in JavaScript code for sorting functionality.

Using the Code

This demo gets data with WebMethod and transfers to client side in JSON format 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 (Having some Change from version1.0)

CREATE PROCEDURE [dbo].[sp_User]
    @operation int=0,
    @StartIndex int=0,
    @PageSize int=0,
    @NumberOfPage int=0,
    @NumberOfPageModulo int=0,
    @TotalRecords int=0,
    @WhereConditionAccount varchar(Max)='',
    @WhereConditionCount varchar(Max)='',
    @EndIndex int=0,
    @PageIndex int=0,
    @Query varchar(max)='',
    @SortOrder varchar(50)=''
AS
BEGIN
    IF(@operation=1)
        BEGIN
            select @NumberOfPage= count(*)/@PageSize,_
            @NumberOfPageModulo= count(*)%@PageSize,@TotalRecords= count(*) from tbl_User

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

            set @Query=';with samp as(
                select ROW_NUMBER() OVER ('+@SortOrder+') AS CountData,* from tbl_User
                )
                select *,'+convert(varchar(50),@NumberOfPage)+' _
                as NumberOfPage,'+convert(varchar(50),@TotalRecords)+' _
                as TotalRecords from samp where CountData between '+_
                convert(varchar(50),@StartIndex)+' and '+_
                convert(varchar(50),((@StartIndex-1)+@PageSize))
                
                execute(@Query)
        END
END
