Ajax控件工具包编译错误ASP.NET

Question

我从nuget添加了AjaxControlToolkit 7.1213版本，并且在.net 4.5中使用了vs 2012，我尝试在我的网站中使用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>

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程序集

      </assemblies>
    </compilation>

这是web.config controls

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

和目标框架工作是3.5任何想法？？？

Answer 1

感谢你的帮助。 通过在web.config的compliation标签中添加属性targetframework即可解决此问题

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

Answer 2

好像您尚未将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到您的DLL所在的目录，然后发出以下命令：

sn -Tp AjaxControlToolkit.dll

Answer 3

如果没有记错，这可能是您的问题，它从web.config文件的下面删除了

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

并将其放在源页面的顶部，不要忘记将tagprefix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和文本框之间没有连接。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>
