CODE BEHIND FILE OF CUSTOM PAGING...

Hi ..

plase find the code for custom paging here it is very simple..

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;

using BusenessObject;
using BusenessLogic;

public partial class CustomPaging : System.Web.UI.Page

{
if (ViewState["GridCurrentPageIndex"] != null && ViewState["GridCurrentPageIndex"].ToString() != "")
{
GridCurrentPageIndex = Convert.ToInt32(ViewState["GridCurrentPageIndex"]);

}
else
{
GridCurrentPageIndex = 1;

}
DisplayBottomPageLinks();
}



protected void click_PreviousPage(object sender, EventArgs e)
{
GridCurrentPageIndex = GridCurrentPageIndex - 1;
Searching();
DisplayBottomPageLinks();
}


protected void BtnShowUser_Click(object sender, EventArgs e)
{

}

}

{

ViewState["count"] = oCustomPaging.TotalRecords;
