错误：ASP.site_master'不包含'btnRegister_Click'的定义

Question

我想为我的ASP.NET空白网站使用Visual Studio 2012使用另一个模板。所以我复制并粘贴了一些代码项目这个项目有不同的模板，现在我得到这个错误：

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?) 

这里是我的代码：

<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> 

我该怎么办？

内，您的主页的代码隐藏文件，写的是这样的：

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