Hello

This is my code

public string constr = ConfigurationManager.ConnectionStrings["ConnectionString"].ToString();
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                BindGridView();
            }
        }

        protected void BindGridView()
        {
            DataTable dt = new DataTable();
            using (SqlConnection con = new SqlConnection(constr))
            {
                string cmdtext = "select ID, CustomerName, ItemName, Price, Qty from TestTable2";
                using (SqlCommand cmd = new SqlCommand(cmdtext, con))
                {
                    con.Open();

Hi asp.ambur,

According to your description, as far as I know, if you want to add one header of the gridview, please check the following sample(OnDataBound event):

Sample Code:

<head runat="server">
    <title></title>
    <style type="text/css">
        body {
            font-family: Arial;
            font-size: 10pt;
        }
    </style>
</head>
<body>
    <form id="form1" runat="server">
        <asp:GridView ID="GridView1" HeaderStyle-BackColor="#9AD6ED" HeaderStyle-ForeColor="#636363"
            runat="server" AutoGenerateColumns="false" OnDataBound="OnDataBound">
            <Columns>
                <asp:BoundField DataField="CustomerName" HeaderText="Name" ItemStyle-Width="150" />
                <asp:BoundField DataField="CustomerCountry" HeaderText="Country" ItemStyle-Width="150" />
                <asp:BoundField DataField="EmployeeName" HeaderText="Name" ItemStyle-Width="150" />
                <asp:BoundField DataField="EmployeeCountry" HeaderText="Country" ItemStyle-Width="150" />
            </Columns>
        </asp:GridView>
    </form>
</body>

protected void Page_Load(object sender, EventArgs e)
    {
        if (!this.IsPostBack)
        {
            DataTable dt = new DataTable();
            dt.Columns.AddRange(new DataColumn[4] { new DataColumn("CustomerName"), new DataColumn("CustomerCountry"), new DataColumn("EmployeeName"), new DataColumn("EmployeeCountry") });
            dt.Rows.Add("John Hammond", "United States", "Albert Dunner", "Bolivia");
            dt.Rows.Add("Mudassar Khan", "India", "Jason Sprint", "Canada");
            dt.Rows.Add("Suzanne Mathews", "France", "Alfred Lobo", "Philippines");
            dt.Rows.Add("Robert Schidner", "Russia", "Shaikh Ayyaz", "UAE");
            GridView1.DataSource = dt;
            GridView1.DataBind();
        }
    }

    protected void OnDataBound(object sender, EventArgs e)
    {
        GridViewRow row = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);
        TableHeaderCell cell = new TableHeaderCell();
        cell.Text = "Customers";
        cell.ColumnSpan = 2;
        row.Controls.Add(cell);

        cell = new TableHeaderCell();
        cell.ColumnSpan = 2;
        cell.Text = "Employees";
        row.Controls.Add(cell);

        row.BackColor = ColorTranslator.FromHtml("#3AC0F2");
        GridView1.HeaderRow.Parent.Controls.AddAt(0, row);
    }

Result:

Best Regards,

Eric Du
