오류 : ASP.site_master '에'btnRegister_Click '에 대한 정의가 없습니다

Question

Visual Studio 2012를 사용하여 ASP.NET 빈 웹 사이트에 다른 템플릿을 사용하려고합니다. 따라서 이전 버전의 일부 코드를 복사하여 붙여 넣었습니다

<div id="login-box" class="login-popup"> 
       <a href="#" class="close"><img src="http://localhost:12345/CAPSTONE/images/process-stop.png" class="btn_close" title="Close Window" alt="Close" /></a> 
        <form class="signin"> 
         <div class="control-group normal_text"><h3>My Site Login</h3></div> 
          <asp:Panel ID="pnlError" runat="server" Visible="false"> 
          <div class="alert alert-error"> 
          <strong>Error!</strong> Invalid username/password. 
         </div> 
         </asp:Panel> 
         <asp:Panel ID="pnlConfirmed" runat="server" Visible="false"> 
         <div class="alert alert-success"> 
          <strong>User Activated!</strong> You may now login. 
         </div> 
         </asp:Panel> 
         <asp:Panel ID="pnlReset" runat="server" Visible="false"> 
         <div class="alert alert-success"> 
          Your password has been changed. You may now login. 
         </div> 
         </asp:Panel> 
         <div class="control-group"> 
         <div class="controls"> 
          <div class="main_input_box"> 
           <span class="add-on"><i class="icon-user"></i></span><asp:TextBox ID="txtEmail" runat="server" MaxLength="70" placeholder="Email Address" /> 
           <span class="add-on"><i class="icon-lock"></i></span><asp:TextBox ID="txtPassword" runat="server" MaxLength="50" TextMode="Password" placeholder="Password" /> 
          </div> 
         </div> 
       </div> 
       <div class="form-actions"> 
        <span class="pull-left"><asp:Button ID="btnRegister" runat="server" 
         class="btn btn-inverse" Text="Register" onclick="btnRegister_Click" /></span> 
        <span class="pull-right"><a href="ForgotPassword.aspx">Forgot Password</a>&nbsp; 
         <asp:Button ID="btnLogin" runat="server" 
         class="btn btn-success" Text="Login" onclick="btnLogin_Click" /> 
        </span> 
       </div> 

어떻게해야합니까 :

ASP.site_master' does not contain a definition for 'btnRegister_Click' and no extension method 'btnRegister_Click' accepting a first argument of type 'ASP.site_master' could be found (are you missing a using directive or an assembly reference?) 

그리고 여기 내 코드입니다 : 다른 템플릿이 프로젝트에 대한 프로젝트는, 지금은이 오류가? 이 같은

마스터 페이지의 코드 숨김 파일 내부

, 쓰기 무언가 :

protected void btnRegister_Click(object sender, EventArgs e) 
{ 
    // do something 
}
