ASPxHTMLEditor控件不仅是一个WYSIWYG编辑器，它还支持HTML输入。您不必选择输入方法，因为此控件提供了视觉编辑器和HTML代码的自动双向同步。 终端用户可以转换到代码查看，并通过控制每个标签和属性编辑文档。您同样可以使用视觉编辑器目前不支持的标签。它们随时可以变换使用最适合当前编辑要求的视图。一旦编辑结束，您可以立即获取在线发布的HTML代码。

为了保证性能优越，编辑器最初生成客户端功能需要的最少代码。当终端用户需要附加要素，例如图片和超链接管理的弹出窗口，这些要素通过AJAX回调载入。对于其他需要与服务器交流的动作，回调是被默认使用的。

ASPx HTMLEditor -用户界面

带有相应按钮的工具条

两个内建的Microsoft Office样式的工具条方便访问所有的功能。例如Office,工具条按钮和集成编辑器会根据目前选择的文本块，自动更新状态或内容。从字型名编辑器到文本和背景颜色按钮，这个对所有的项都有效。

利用DevExpress ASPxMenu控件，可以建立ASPxHTMLEditor工具条。

自定义工具条和客户端API

如果需要，您能够自定义编辑器的界面，隐藏标准的工具条，并可以增加任何数量的工具条，增加的工具条可以包括现有命令或自定义命令。当使用自定义命令时，您可以使用ASPxHTML提供的客户端API，它允许你调用一系列内建的命令，如删除，应用格式化等。

HTML视图
如果你需要访问产生的HTML代码，或如果有些工作在代码下工作更方便，你可以切换到HTML视图。当你切换回，调用服务器端验证和同步。这些操作通过AJAX callbacks完成以保证最高水平的响应速度。

HTML允许您通过视觉编辑器内建指令，键入目前不能被管理的元素。如果具有这些无支持元素的文本，您仍然可以在设计视图下通过编辑器工具条定制格式化。

内建上下文菜单
当你右键点击对象，ASPxHTMLEditor重载缺省的浏览器菜单，并显示它自己的菜单，使编辑命令更加容易访问。依靠点击对象，你可以获取到略微不同的命令集。例如右键点击了一副图片后，您就可以直接从文本菜单调用图片自定义对话框。

ASPxHTML Editor - 编辑特点

文本和段落格式化

支持所有基本的文本和段落格式化特征，如下图所示。

嵌入图片
为嵌入的图片，简单点击工具条上的按钮，弹出模态对话框，它提供2个图片来源选项。一种是从你本地硬盘上传图片到web站点的一个文件夹中。另一个是简单地指向一个图片URL。不管您选择了哪种方法，您都可以用对话框自定义图片大小，位置和提示文本。添加图片后，在设计视图中您可以用简单的拖放操作重新调整图片大小，放置图片位置。

通过AJAX回调调用图片自定义文本框。这就意味着较少的HTML代码首先下载到了客户端。

超链接
超链接特征与嵌入图片特征十分相似。有两个内建工具条按钮使您可以链接或取消选中的一段文本。您还可以弹出一个AJAX对话框设定目标URL和其他相关联的属性。最后，当您右键点击设计视图的链接时，会有一个专门的文本菜单项可以使链接自定义更加的明确。

多级Undo和Redo操作
ASPxHTMLEditor保留了所有的操作，允许你返回操作或重复相同的操作。您还可以使用工具条按钮或CTRL+Z和CTRL+Y快捷键-与您在Microsoft Word或其他的文本编辑器当中使用一样。

安全保证
ASPxHTMLEditor支持HTML代码，这是发起web服务器的一种方法。恶意攻击一种最明显的方法是通过将脚本插入到图片加载处理程序中来执行它。为了阻止它的发生，ASPxHTMLEditor实现智能脚本验证，可以删除恶意代码（如果您不介意这些脚本，您可以选择关掉该脚本删除机制）。

另外一种危害势源是链接其他web网站的图片。为了避免链接，我们的图片插入对话框允许您将图片下载到web网站上传文件夹。通过这种方法，您就可以直接本地复制，而不需依靠外部资源了。

ASPxHTML Editor -打印和数据交换

从Microsoft Word复制

我们都知道， 微软Word输出产生的HTML相当冗长，它包含大量的属性，而这些在产生相同文档视图时不是真正需要的。当您需要将文本从Microsoft Word复制到the ASPxHTML Editor上时，所有的这些非必需的属性也被复制了。

现在新的ASPxHTML Editor允许你自动地排除这些额外的属性，获得更干净和紧凑的HTML代码。

打印HTML Editor内容
打印ASPxHTML Editor的内容非常方便，您的最终用户只需点击一个打印按钮。

In addition to being a WYSIWYG editor, the ASPxHTMLEditor control supports HTML input. You don't have to choose which input method to use, because the control provides automatic two-way synchronization between the visual editor and HTML code. End-users can switch to the code view and edit documents by manually controlling every tag and attribute. This allows them to use even those tags that aren't currently supported by the visual editor. At any time, they can switch back and forth to use the view that best suits their current editing requirements. Once editing has been completed, you instantly obtain HTML code to be published online.

To ensure superior performance, the editor initially generates the least amount of code required for its functionality on the client. When end-users need additional elements, such as popup windows for image or hyperlink management, these elements are loaded via AJAX callbacks. Callbacks are also used by default for all other actions that require communication with the server.

ASPx HTMLEditor - User Interface

Toolbars with Responsive Buttons

Two built-in Microsoft® Office® style toolbars provide easy access to all available functions. Just like Office, toolbar buttons and integrated editors automatically update their state or content, depending upon the currently selected text block. This works for all items – from the font name editor to buttons specifying text and background color.

The toolbars in the ASPxHTMLEditor were built using the DevExpress ASPxMenu control.

Custom Toolbars and Client-Side API

If needed, you can customize the editor's UI by hiding standard toolbars and adding any number of toolbars that include existing or custom commands. When implementing custom commands, you can make use of our client-side API, which allows you to invoke any sequence of built-in commands like deleting text, applying font formatting, etc.

HTML View

If you need access to the generated HTML code, or if it's easier to do something in code, you can switch to the HTML view, and edit markup that represents the current content. When you switch back and forth, server-side validation and synchronization are invoked. These operations are done via AJAX callbacks to guarantee the highest level of responsiveness.

Note that HTML editing allows you to embed elements that currently can't be managed via the visual editor's built-in commands. And if you have text within those unsupported elements, you will still be able to customize its formatting via the editor's toolbars when in design view.

Built-in Context Menus

When you right-click an object, the ASPxHTMLEditor overrides the default browser menu and displays its own menu making editing commands easily available. Depending on the clicked object, you get slightly different command sets. For instance, if you've right-clicked an image, you can invoke the image customization dialog directly from the context menu.

ASPxHTML Editor - Editing Features

Text and Paragraph Formatting

As one might expect, our editor fully supports all basic text and paragraph formatting features, as shown in the following image.

Embedded Images

To embed images, simply click a toolbar button. This will invoke a modal popup dialog that provides two options for getting an image. One way is to upload an image from your hard drive to a special folder on the web site. Another is to simply refer to an image by URL. Whichever method you choose, the dialog allows you to specify custom image size, alignment and hint text. After an image has been added, the design view allows you to resize and re-locate the image using simple drag and drop operations.

The image customization dialog is invoked via an AJAX callback. This means that less HTML code is initially downloaded to the client.

Hyperlinks

The functionality related to hyperlinks is pretty much the same as with embedded images. There are two built-in toolbar buttons allowing you to link or unlink a selected text fragment. You get an AJAX-enabled popup dialog that specifies the target URL and other link-related attributes. Finally, when you right-click a link in design view, there's a special context menu item making link cusotmization more straightforward.

Multi-level Undo and Redo Operations

The ASPxHTMLEditor keeps track of all operations, allowing you to rollback to an earlier version or to repeat the same customizations. You can either use toolbar buttons or standard keyboard shortcuts - CTRL+Z and CTRL+Y - as you would do in Microsoft Word or any other text editor.

Security Assurance

The ASPxHTMLEditor accepts HTML code, which is a way to initiate web server attacks. One very obvious method used in malicious attacks is to run a script by inserting it into an image's Load event handler. To prevent this, our editor implements smart script validation that removes scripts, if assigned. (If you don't mind scripts, there's an option to turn off this script removal mechanism.)

Another potential source of harm is having links to images on other web sites. To avoid such links, our image insertion dialog allows you to download an image to the web site's upload folder. This way, you'll use a local copy rather than referring to an external resource.

ASPxHTML Editor - Printing and Data Exchange

Pasting from Microsoft Word

As we all know, the HTML output produced by Microsoft Word is pretty lengthy. It contains lots of attributes that aren't really required to produce the same document view. When you needed to copy text from Microsoft Word to the ASPxHTML Editor, all those unnecessary attributes were copied.

With this release, our HTML Editor control allows you to automatically eliminate these extra attributes and obtain cleaner and more compact HTML code.

Print HTML Editor Content

Printing the contents of the ASPxHTML Editor is now a piece of cake – just a single click for your end users.
