asp.net - HtmlEditorExtender 默认样式

Question

我的页面上有一个 ajax HtmlEditorExtender，如下所述:

http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/HTMLEditorExtender/HTMLEditorExtender.aspx

问题是，它没有任何默认样式。结果，我有一堆没有图像或任何东西的普通按钮。我试着找到这个所谓的“Editor.css”页面，如下所述:http://www.asp.net/ajaxlibrary/act_HTMLEditor.ashx ，但它似乎并不存在于任何地方。它在我的开发服务器上执行此操作，但在我的生产服务器上，它什么也不做(只是一个普通的文本框)。有人可以帮忙吗？

下面是我的aspx代码

这是我得到的:

Answer 1

您的开发环境或服务器(或两者)是否遇到此问题？

这些图像来自一个名为“WebResource.axd”的文件——您在元素中看不到它，但它是由 AjaxControlToolkit 库自动生成的。在没有看到您的代码或问题示例的情况下，我猜测您的库可能没有在您的元素中正确设置。

设置它的一种简单方法是使用库包管理器 (Nuget) 将库安装到您的网站中。这不仅会设置引用，还会配置您的 web.config。仅供引用，我只是做了以下测试:

1) 在 Visual Studio 中创建一个新的空 ASP.NET 元素2)在元素中添加了一个新的webform3) 从您提供的页面复制示例 HTML 编辑器标记并将其粘贴到我的新表单中4) 在页面中添加了一个 ToolkitScriptManager 和 TextBox，就在表单下方和 HTML 编辑器之前:

<ajaxToolkit:ToolkitScriptManager ID="tsm" runat="server"></ajaxToolkit:ToolkitScriptManager>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

5) 将以下属性添加到 HTML 编辑器的标记中(我不建议您这样做 - 我这样做只是为了快速测试):

EnableSanitization="false"

我会自己尝试，如果可行，请比较您的两个元素的不同之处。如果没有，请使用指向您网站的公开链接(如果可能)或您的 HTML 编辑器标记更新此帖子。
