How to make Header fixed in GridView

Here we are binding a GridView in Asp.Net.

Points Of Remember:

1. Write a Css for GridView header position.
2. Add the Css in GridView's HeaderStyle tag.
3. Set column header width.
<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
   <style type="text/css">
       .header { position:absolute; }
   </style>
</head>
<body>
    <form id="form1" runat="server">
    <div style="overflow:scrollheight:250pxwidth:600px;" >
         <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false"
               CellPadding="4" ForeColor="#333333" Width="600px">
            <Columns>
                <asp:BoundField DataField="Name" HeaderText="Name" HeaderStyle-Width="271px" />
                <asp:BoundField DataField="Branch" HeaderText="Branch" HeaderStyle-Width="91px"/>
                <asp:BoundField DataField="City" HeaderText="City" HeaderStyle-Width="194px" />
            </Columns> 
            <HeaderStyle CssClass="header" BackColor="#7961da"
                                                                Font-Bold="True" ForeColor="White" />       
            <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
         </asp:GridView>
    </div>
    </form>
</body>
</html>

C# Codes :

using System.Data;
using System.Data.SqlClient;

public partial class GridView : System.Web.UI.Page
{
    SqlConnection con = new SqlConnection(@"Data Source=RAVI-PC\SQL;Initial
                                                                              Catalog=db_Student;Integrated Security=True");

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            BindGridView();
        }
    }
    //method for binding GridView
    protected void BindGridView()
    {
        DataTable dt = new DataTable();       
        SqlDataAdapter da = new SqlDataAdapter("Select Name,Branch,City from tbl_student", con);
        con.Open();
        da.Fill(dt);
        con.Close();

        if (dt.Rows.Count > 0)
        {
            GridView1.DataSource = dt;
            GridView1.DataBind();
        }
    }
}
