Ajax控件工具包编译错误ASP.NET

Question

我从nuget添加了AjaxControlToolkit 7.1213版本，我在.net 4.5中使用vs 2012，我尝试在我的网站中使用calenderextender，如下所示

<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，我得到了以下错误：

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'.

这是程序集--我的Web.config

      </assemblies>
    </compilation>

这是controls in web.config

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

目标框架工作是3.5，有什么想法吗？？

Answer 1

谢谢大家的帮助。通过在web.config中添加属性tag框架中的遵从标记来解决这个问题，如下所示

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

Answer 2

看来您还没有将AjaxControlToolkit程序集添加到程序集部分。你能试着把它加进去然后再重新测试吗？

编辑:要获得PublicKeyToken，请打开Visual命令提示符，光盘到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，这可能是您的问题从您的web.config文件中删除以下一行。

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

并将其放在源页面的顶部，并且不要忘记将标记前缀放在最后，这意味着在名称空间声明之后。

<%@ 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.For之间没有连接，您必须使用“TargetControlID”

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

更新

将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>
