Accepted answer

In ASP.NET Web Forms, there is no specific controller class like in ASP.NET MVC. However, you can create a regular class and use it to handle requests by implementing the IHttpHandler interface.

public class MyHandler : IHttpHandler {
    
    public void ProcessRequest(HttpContext context) {
        // Handle the request here
        string response = "Hello World!";
        context.Response.Write(response);
    }
    
    public bool IsReusable {
        get { return false; }
    }
}

To use this class to handle requests, you need to register it in the RouteConfig class. You can do this by adding a new route to the RouteTable:

public class RouteConfig {
    public static void RegisterRoutes(RouteCollection routes) {
        routes.Ignore("{resource}.axd/{*pathInfo}");
        
        // Register the custom route
        routes.Add(new Route("myroute", new MyRouteHandler()));
    }
}

public class MyRouteHandler : IRouteHandler {
    public IHttpHandler GetHttpHandler(RequestContext requestContext) {
        return new MyHandler();
    }
}

 Decimal dPageTotal;

private void GetCustomersPageWise(int pageIndex)
{
    using (SqlCommand cmd = new SqlCommand("GetCustomersPageWise", con))
    {
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@PageIndex", pageIndex);
        cmd.Parameters.AddWithValue("@PageSize", int.Parse(ddlPageSize.SelectedValue));
        cmd.Parameters.Add("@RecordCount", SqlDbType.Int, 4);
        cmd.Parameters["@RecordCount"].Direction = ParameterDirection.Output;
        con.Open();
        IDataReader idr = cmd.ExecuteReader();
        GridView1.DataSource = idr;
        GridView1.DataBind();
        idr.Close();
        con.Close();
        int recordCount = Convert.ToInt32(cmd.Parameters["@RecordCount"].Value);
        this.PopulatePager(recordCount, pageIndex);
    }
}

CREATE PROCEDURE GetCustomersPageWise  
      @PageIndex INT = 1  
      ,@PageSize INT = 10  
      ,@RecordCount INT OUTPUT  
AS  
BEGIN  
      SET NOCOUNT ON;  
      SELECT ROW_NUMBER() OVER  
      (

     INTO #Results  
      FROM newtable  
       
      SELECT @RecordCount = COUNT(*)  
      FROM #Results  
             
      SELECT * FROM #Results  
      WHERE RowNumber BETWEEN(@PageIndex -1) * @PageSize + 1 AND(((@PageIndex -1) * @PageSize + 1) + @PageSize) - 1  
       
      DROP TABLE #Results  
END

void BindData()
{
    SqlCommand cmd = new SqlCommand("select * from newtable", con);
    SqlDataAdapter da = new SqlDataAdapter(cmd);
    DataTable dt = new DataTable();
    da.Fill(dt);
    if (ViewState["TotalPrice"] == null)
    {
        Decimal dPrice = 0;
        for (int i = 0; i <= dt.Rows.Count - 1; i++)
        {                  
            dPrice += dt.Rows[i].Field(10);
        }
        ViewState["TotalPrice"] = dPrice;
    }
    GridView1.DataSource = dt;
    GridView1.DataBind();
}

alter table newtable add amount numeric(18,2)

private void PopulatePager(int recordCount, int currentPage)
{
    double dblPageCount = (double)((decimal)recordCount / decimal.Parse(ddlPageSize.SelectedValue));
    int pageCount = (int)Math.Ceiling(dblPageCount);
    List pages = new List();
    if (pageCount > 0)
    {
        pages.Add(new ListItem("First", "1", currentPage > 1));
        for (int i = 1; i <= pageCount; i++)
        {
            pages.Add(new ListItem(i.ToString(), i.ToString(), i != currentPage));
        }
        pages.Add(new ListItem("Last", pageCount.ToString(), currentPage < pageCount));
    }
    rptPager.DataSource = pages;
    rptPager.DataBind();
}
