You have to place your controls in a form element:

<form ID="form1" runat="server">
    <table>
        <tr><td>First Name:</td><td><asp:TextBox ID="TextBox1" runat="server"></asp:TextBox></td></tr>
        <tr><td>Last Name:</td><td><asp:TextBox ID="TextBox2" runat="server"></asp:TextBox></td></tr>
        <tr><td>Username:</td><td><asp:TextBox ID="TextBox3" runat="server"></asp:TextBox></td></tr>
        <tr><td>Passowrd:</td><td><asp:TextBox ID="TextBox4" TextMode="Password" runat="server"></asp:TextBox></td></tr>
        <tr><td>Confirm Password:</td><td><asp:TextBox ID="TextBox5" TextMode="Password" runat="server"></asp:TextBox></td></tr>
        <tr><td>Gender:</td>
            <td>
                <asp:RadioButtonList ID="RadioButtonList1" runat="server">
                    <asp:ListItem>Male</asp:ListItem>
                    <asp:ListItem>FeMale</asp:ListItem>
                </asp:RadioButtonList>
            </td>
        </tr>
        <tr><td>Email:</td><td><asp:TextBox ID="TextBox6" TextMode="Email" runat="server"></asp:TextBox></td></tr>
        <tr><td><asp:Button ID="Button1" Text="Register" runat="server"/></td></tr>
    </table>
</form>
