HTMLEditorExtender 导致“Key 不能为 null”错误

发布于 2024-12-10 14:01:09 字数 3519 浏览 0 评论 0原文

我的 ASP.Net C# 项目编译并运行良好，除非我尝试加载带有 Ajax Control Toolkit HTMLEditorExtender 的特定页面。我收到“密钥不能为空页面”错误。我尝试删除 htmleditorextender 并放置一个 asynchfileupload 控件，只是为了确保脚本管理器正常工作，并且页面正常显示并且上传控件正常工作。所以这是专门针对 htmleditorextender 的。这是我的代码：

<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>

显示页面错误的行是这一行：

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

这是堆栈跟踪：

[ArgumentNullException: Key cannot be null.
Parameter name: key]

   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75

任何帮助将不胜感激。我尝试用谷歌搜索此错误，但找不到似乎有效的解决方案。

My project in ASP.Net C# is compiling and running fine except for when I try to load a specific page which has an Ajax Control Toolkit HTMLEditorExtender on it. I get a Key cannot be null page error. I tried removing the htmleditorextender and putting an asynchfileupload control instead just to make sure the scriptmanager was working, and the page comes up fine and the upload control works. So it is something with the htmleditorextender specifically. Here is the code I have:

<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>

The line that shows the error on the page error is this one:

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

This is the stack trace:

[ArgumentNullException: Key cannot be null.

Any help would be greatly appreaciated. I've tried googling this error and can't find a solution that seems to work.

我不知道这是否是您的问题，但是当我在 system.web 的 web.config 中没有以下部分时，我遇到了这个问题：

 ;
       <提供商>
           <添加名称=“AntiXssSanitizerProvider”类型=“AjaxControlToolkit.Sanitizer.AntiXssSanitizerProvider”>

您还需要在配置部分中包含以下内容：

 
       <部分名称=“消毒剂”requirePermission=“false”
                类型 =“AjaxControlToolkit.Sanitizer.ProviderSanitizerSection，AjaxControlToolkit”/>

I don't know if this will be your problem, but I encountered this when I didn't have the following section in my web.config in system.web:

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

You'll also need to have this in your configsections:

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

您必须将这些行添加到您的 web.config

Configsectons：

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

System.web

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

您的麻烦应该会消失，就像它们为我所做的那样。
如果有任何帮助，我通过查看对象浏览器找到了解决方案。

You have to add these lines to your web.config

Configsectons:

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

System.web

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

Your troubles should go away as they did for me.
If its of any help I found the solution by looking in the Object browser.
