HTMLEditorExtender導致'密鑰不能爲空'錯誤

我在ASP.Net中的項目C＃編譯和運行正常，除了當我嘗試加載一個具有Ajax控件工具包HTMLEditorExtender的特定頁面。我得到一個密鑰不能爲空頁錯誤。我嘗試刪除htmleditorextender並放置一個asynchfileupload控件，而不是僅僅爲了確保scriptmanager正在工作，並且頁面正常運行並且上傳控件可以工作。所以這與htmleditorextender具體有關。下面是我的代碼有：HTMLEditorExtender導致'密鑰不能爲空'錯誤

<asp:TextBox ID="txtMailMsgContent" TextMode="MultiLine" runat="server"/> 
<cc1:HtmlEditorExtender ID="HTMLEditorExtender" runat="server" 
TargetControlID="txtMailMsgContent"> 

      <Toolbar> 
       <cc1:Undo /> 
       <cc1:Redo /> 
       <cc1:Bold /> 
       <cc1:Italic /> 
       <cc1:Underline /> 
       <cc1:StrikeThrough /> 
       <cc1:Subscript /> 
       <cc1:Superscript /> 
       <cc1:JustifyLeft /> 
       <cc1:JustifyCenter /> 
       <cc1:JustifyRight /> 
       <cc1:JustifyFull /> 
       <cc1:InsertOrderedList /> 
       <cc1:InsertUnorderedList /> 
       <cc1:CreateLink /> 
       <cc1:UnLink /> 
       <cc1:RemoveFormat /> 
       <cc1:SelectAll /> 
       <cc1:UnSelect /> 
       <cc1:Delete /> 
       <cc1:Cut /> 
       <cc1:Copy /> 
       <cc1:Paste /> 
       <cc1:BackgroundColorSelector /> 
       <cc1:ForeColorSelector /> 
       <cc1:FontNameSelector /> 
       <cc1:FontSizeSelector /> 
       <cc1:Indent /> 
       <cc1:Outdent /> 
       <cc1:InsertHorizontalRule /> 
       <cc1:HorizontalSeparator /> 
      </Toolbar> 
     </cc1:HtmlEditorExtender>

，顯示頁面錯誤的錯誤行是這一個：

<cc1:HtmlEditorExtender ID="HTMLEditorExtender" runat="server" TargetControlID="txtMailMsgContent">

這是堆棧跟蹤：

任何幫助會大大appreaciated。我試着用Google搜索這個錯誤，並找不到似乎可行的解決方案。

嘗試由Bertzzie提供的解決方案http://stackoverflow.com/questions/12022493/could-not-load-type-ajaxcontroltoolkit-sanitizer-antixsssanitizerprovider。它適用於我。 –

我不知道這是否會是你的問題，但我遇到了這個時候，我沒有在System.Web程序在我的web.config以下部分：

<sanitizer defaultProvider="AntiXssSanitizerProvider"> 
     <providers> 
      <add name="AntiXssSanitizerProvider" type="AjaxControlToolkit.Sanitizer.AntiXssSanitizerProvider"></add> 
     </providers> 
    </sanitizer>

您還需要有這個在您的configsections：

<sectionGroup name="system.web"> 
     <section name="sanitizer" requirePermission="false" 
       type="AjaxControlToolkit.Sanitizer.ProviderSanitizerSection, AjaxControlToolkit" /> 
    </sectionGroup>

     </asp:AnimationExtender> 
    </div> 
    </form> 
</body> 
</html>

試試這個代碼，不要使在web.config文件中的任何改變我得到相同的異常早，但是當我嘗試這一點，得到了解決

您必須添加這些行到你的web.config

Configsectons：

<configSections> 
    <sectionGroup name="system.web"> 
     <section name="sanitizer" requirePermission="false" type="AjaxControlToolkit.Sanitizer.ProviderSanitizerSection, AjaxControlToolkit" /> 
    </sectionGroup> 
</configSections>

的System.Web

<system.web> 
    <sanitizer defaultProvider="AntiXssSanitizerProvider"> 
    <providers> 
     <add name="AntiXssSanitizerProvider" type="AjaxControlToolkit.Sanitizer.HtmlAgilityPackSanitizerProvider" /> 
    </providers> 
    </sanitizer>

你的麻煩應該消失，就像他們爲我做的那樣。如果有任何幫助，我會通過在對象瀏覽器中查找找到解決方案。
