「ControlBox'ContentPlaceHolder1_txtReason'類型'TextBox'必須放置在runat = server的表單標籤內。」}

-1

我是asp.net的初學者。我不停地收到上述錯誤「ControlBox'ContentPlaceHolder1_txtReason'類型'TextBox'必須放置在runat = server的表單標籤內。」}

類型「文本框」控制「ContentPlaceHolder1_txtReason」必須放在一個表單標籤內有RUNAT =服務器。「}

而且我不能釘問題它的頭上。

希望有人能指出我的錯誤。

您應該將<form runat="server" id="form1">。

<body>   
    <form id="form1" runat="server"> 
     // You should code for your controls inside this block. This runat="server" indicates that a control is being treated as a server control. 
     </form> 
    </body>
