How can we retrive data from database into listbox or gridview?

DataClassesDataContext Db = new DataClassesDataContext();
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            //retrieve data from Db through linq Ado.net ....etc
            var result = from x in Db.Genders
                         select new { x.gender1, x.test };
            //passing the datasource for control
            ListBox1.DataSource = result;
            // here the the value will dispaly
            ListBox1.DataTextField = "gender1";
            // value field
            ListBox1.DataValueField = "test";
            //bind control
            ListBox1.DataBind();
            //passing datasource
                GridView1.DataSource = result;
                GridView1.DataBind();
        }
    }

<div>
      <asp:ListBox ID="ListBox1" runat="server"></asp:ListBox>
      <br />
      <br />
      <asp:GridView ID="GridView1" runat="server">
      </asp:GridView>
  </div>
