此頁面缺少要添加的 CSS 樣式錶鍊接所需的 HtmlHead 控制項。請添加 <head runat=‘server’ />
我有頁面並添加了 Ajax 擴展，但它給我拋出了錯誤
我正在使用母版頁，所以這個頁面沒有
<head>頁面程式碼

可能這會對你有所幫助。母版頁 Html
<asp:ContentPlaceHolder ID="head" runat="server"> </asp:ContentPlaceHolder> <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server"> </asp:ContentPlaceHolder>子頁面 Html
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">Add Scripts here</asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server"> Add Page Content Here</asp:Content>
在母版頁中添加
<head runat="server">
