Hi dongtrien,
If you look at my example sent this website, you can fix it, I don't know how to fix my example error
You could refer to below codes:
You should replace the namespace to your own namespace
ASPX PAGE:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="TestNameSpace.aspx.cs" Inherits="WebFormForComplieTest.TestNameSpace" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Label ID="lblName" runat="server" Text="Tìm kiếm:"></asp:Label>
<asp:TextBox ID="txtSearch" runat="server"></asp:TextBox>
<asp:Button ID="btnSearch" runat="server" Text="Search" OnClick="btnSearch_Click" />
<asp:Label ID="lblMessage" runat="server"></asp:Label>
<br />
<br />
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>
</div>
</form>
</body>
</html>

if (!IsPostBack)
{
LoadData();

}
string sSQL;
private void LoadData()
{
sSQL = "SELECT NGAY, MASOPHIEU, KHACHDUA, TONGTIEN, TONGTHU, TENKH, TEL, ADRESS, GIAM, DOITRA, TTTHANHTOAN, THANHTOAN, MANHANVIEN, NHANVIEN ";

//DataTable dtKhachNoTmp = clsConnecACS.FillDatatable(sSQL);

lblMessage.Text = "Nhập [Tên nhân viên] cần tìm";
}
else
{
lblMessage.Text = "";
LoadData(txtSearch.Text.Trim());
}
}
}
}
