Ajax控件工具包編譯錯誤ASP.NET

Question

我從nuget添加了AjaxControlToolkit 7.1213版本，並且在.net 4.5中使用了vs 2012，我嘗試在我的網站中使用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>

嘗試調試項目時，出現以下錯誤：

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'.

這是我的Web.config程序集

      </assemblies>
    </compilation>

這是web.config controls

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

和目標框架工作是3.5任何想法？？？

Answer 1

感謝你的幫助。 通過在web.config的compliation標簽中添加屬性targetframework即可解決此問題

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

Answer 2

好像您尚未將AjaxControlToolkit程序集添加到“程序集”部分。 您可以嘗試添加它，然后重新測試嗎？

編輯：要獲取PublicKeyToken，請打開Visual Studio命令提示符，cd到您的DLL所在的目錄，然后發出以下命令：

sn -Tp AjaxControlToolkit.dll

Answer 3

如果沒有記錯，這可能是您的問題，它從web.config文件的下面刪除了

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

並將其放在源頁面的頂部，不要忘記將tagprefix放在最后，這意味着在命名空間聲明之后。

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

並在源頁面中進行這樣的更改，因為ajaxtoolkit和文本框之間沒有連接。為此，您必須使用“ TargetControlID”

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

更新

將您的webconfig文件更改為

<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>
