我有页面并添加Ajax扩展名，但它为我抛出了错误
我正在使用母版页，因此此页没有<head>
页面代码
<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" runat="server" %>

<table style="width: 100%">

<td colspan="5" style="text-align: center; height: 20px;">Search </td>
</tr>
<tr>
<td style="text-align: center; height: 20px;">Ticket number</td>
<td style="text-align: center; height: 20px;">Client name</td>
<td style="text-align: center; height: 20px;">Address</td>
<td style="text-align: center; height: 20px;">Assigned to</td>
<td style="text-align: center; height: 20px;">Date</td>
</tr>
<tr>
<td style="width: 157px">
<asp:TextBox ID="txt_incID" runat="server" Width="146px"></asp:TextBox>

</td>

<asp:SqlDataSource ID="Ds_address" runat="server" ConnectionString="<%$ ConnectionStrings:TicketsConnectionString %>" SelectCommand="SELECT * FROM [Streets]"></asp:SqlDataSource>
<asp:SqlDataSource ID="DS_Employee" runat="server" ConnectionString="<%$ ConnectionStrings:TicketsConnectionString %>" SelectCommand="SELECT * FROM [Employee]"></asp:SqlDataSource>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
</asp:Content>
在其他主题中，人们建议添加此内容
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>但我在页面上有它。任何想法如何解决？

可能会对您有帮助。
母版页HTML
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
子页面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>
关于asp.net - 此页面缺少要添加的CSS样式表链接所需的HtmlHead控件。请添加<head runat ="server"/>，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/18371538/
