Ajax Control Toolkit 编译错误 ASP.NET

Question

我从 nuget 添加了 AjaxControlToolkit 版本 7.1213，我有 .net 4.5 的 vs 2012 我尝试像这样在我的网站中使用calenderextender

<ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</ajaxToolkit:ToolkitScriptManager>
<asp:TextBox ID="birthtxt" runat="server" Style="width: 95%;" />
<ajaxToolkit:CalendarExtender ID="CalendarExtender1" runat="server"></ajaxToolkit:CalendarExtender>

在尝试调试项目时出现以下错误：

Error   1   The type 'System.Web.UI.ScriptManager' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.


Error   2   The type 'System.Web.UI.ExtenderControl' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

这是我的Web.config的程序集

      </assemblies>
    </compilation>

这是controls in web.config

   <pages>
      <controls>
        <add tagPrefix="ajaxToolkit" assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" />
      </controls>
    </pages>

目标框架是 3.5 有什么想法？？？

Answer 1

感谢大家的帮助。通过在web.config 中添加类似这样的属性targetframework 的编译标记来解决问题

<compilation debug="true" targetFramework="4.5">

Answer 2

看起来您还没有将 AjaxControlToolkit 程序集添加到“程序集”部分。您可以尝试添加它然后重新测试吗？

编辑：要获取 PublicKeyToken，请打开 Visual Studio 命令提示符，cd 到 DLL 所在的目录，然后发出以下命令：

sn -Tp AjaxControlToolkit.dll

Answer 3

如果没有错，这可能是您从 web.config 文件中删除的问题

<add tagPrefix="ajaxToolkit" assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" />

并将它放在源页面的顶部，并且不要忘记将标记前缀放在最后，这意味着在命名空间声明之后。

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>

并在源页面中进行这样的更改，因为 ajaxtoolkit 和 textbox 之间没有连接。为此，您必须使用 'TargetControlID'

<ajaxToolkit:CalendarExtender ID="CalendarExtender1" runat="server" TargetControlID="birthtxt">
    </ajaxToolkit:CalendarExtender>

更新

将您的 webconfig 文件更改为，

<pages>
<controls>

<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions,Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add namespace="AjaxControlToolkit" assembly="AjaxControlToolkit" 
        tagPrefix="ajaxToolkit"/>
</controls>
</pages>
