validation showing in both panels in asp.net

i am using two panels (login and registration) in asp.net where in both panels i used button control. and i also used validations for particular textboxes in both panels. i want to show both panels at same time. now what problem i am facing is that when i click on button of login panel, it shows validation error text in registration panel and vice-versa..

Is there nay other way to use any other control instead of button. i am using visual studio-2008

i had created login panel as:

  <asp:Panel ID="pnllogin" runat="server">
                <table class = "style1">
                <tr>
                <td>
                <asp:Label ID="lblloginid" runat="server" Text="Login_ID" Font-Bold="true"></asp:Label>
                </td>
                <td>
                <asp:TextBox ID="txtboxloginid" runat="server" ></asp:TextBox>
                <asp:RequiredFieldValidator ID="requiredfieldvalidator1" runat="server" 
                ControlToValidate="txtboxloginid" ErrorMessage="*" ForeColor="Red"></asp:RequiredFieldValidator>
                </td>                
                </tr>

                <tr>
                <td>
                <asp:Label ID="lblpassword" runat="server" Text="Password" Font-Bold="true"></asp:Label>                
                </td>
                <td>
                <asp:TextBox ID="txtboxpassword" runat="server"></asp:TextBox>
                <asp:RequiredFieldValidator ID="requiredfieldvalidator2" runat="server" 
                ControlToValidate="txtboxpassword" ErrorMessage="*" ForeColor="Red"></asp:RequiredFieldValidator>
                </td>
                </tr>
               <tr>
               <td></td>
               <td>
               <asp:HyperLink ID="hyperlinkforgotpassword" runat="server" ForeColor="Red" NavigateUrl="~/ForgotPassword.aspx">Forgot Password??</asp:HyperLink>
               </td>
               </tr>

               <td>&nbsp;</td>
               <td>
