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 System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

using System.Diagnostics; // Debug
using connectSQL; // warning

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
LoadData();
}
}
string sSQL;

private void LoadData()
{

sSQL = "SELECT * FROM TABKHACHHANG ";
sSQL += "ORDER BY MASOPHIEU;";
    GridView1.DataSource = ClsConnecSQL.FillDatatable(sSQL); //warning
}

}

//file: clsConnecSQL.cs

using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
//using connectSQL;

namespace connectSQL
{
public class ClsConnecSQL
{
public static DataTable FillDatatable(string sSQL)
{
//Do somthing...
}
}

}

using connectSQL; // warning
GridView1.DataSource = ClsConnecSQL.FillDatatable (sSQL); // error not found connectSQL namespace
