AjaxControlToolkit--HtmlEditor

HtmlEditor在AjaxControlToolkit的上个版本中就已经提供了，属于一个功能比较简单的Html在线编辑器，虽说功能不多，不过对只需要基础的应用差不多已经足够了。

使用HtmlEditor很简单，只要在页面上注册了AjaxControlToolkit，先望页面里拖个拖个ScriptManager进去，再从工具箱里把Editor拖出来就行了（前提是已添加了AjaxControlToolkit的引用，并将所包含的控件放到了工具箱）

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="editor.aspx.cs" Inherits="editor" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit.HTMLEditor"
    TagPrefix="cc1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script type="text/javascript">
    
      function pageLoad() {
      }
    
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server" />
        <cc1:Editor ID="Editor1" runat="server" Width="500px" Height="300px"/>
    </div>
    </form>
</body>
</html>

上个图看下效果：

挺傻瓜化的吧。

其实HtmlEditor的最大好处是我们可以方便的自己定义在HTML编辑器上所需要的功能。

下面让我们先来添加一个类：myeditor.cs

在其中添加三个引用命名空间：

using AjaxControlToolkit.HTMLEditor;
using System.Collections;
using System.Collections.ObjectModel;

然后添加自己的命名空间（这里就叫myhtmleditor吧），然后添加一个类（这里我们叫myeditor吧）继承自Editor

namespace myhtmleditor
{
    public class myeditor:Editor
    {
    }
}

然后我们重写两个事件FillTopToolbar和FillBottomToolbar就可以定制我们自己想要的HtmlEditor了

        protected override void FillTopToolbar()
        {
        }

        protected override void FillBottomToolbar()
        {
        }

其中FillTopToolbar是HtmlEditor上方的菜单，FillBottomToolbar是HtmlEditor下方的菜单

可以设定的有：

            //定义下拉菜单金集合
            Collection<AjaxControlToolkit.HTMLEditor.ToolbarButton.SelectOption> options;
            //定义下拉菜单
            AjaxControlToolkit.HTMLEditor.ToolbarButton.SelectOption option;
            //菜单栏上的分割符
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.HorizontalSeparator());
            //撤销
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.Undo());
            //重做
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.Redo());
            //加粗
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.Bold());
            //倾斜
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.Italic());
            //下划线
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.Underline());
            //文字中划线
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.StrikeThrough());
            //上标
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.SuperScript());
            //下标
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.SubScript());
            //从左向右排列
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.Ltr());
            //从右向左排列
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.Rtl());

            //文字颜色按钮
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.ForeColor());
            //文字颜色下拉菜单
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.ForeColorSelector());
            //取消文字颜色
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.ForeColorClear());

            //另一种定义文字颜色的方法
            AjaxControlToolkit.HTMLEditor.ToolbarButton.FixedForeColor FixedForeColor = new AjaxControlToolkit.HTMLEditor.ToolbarButton.FixedForeColor();
            TopToolbar.Buttons.Add(FixedForeColor);
            AjaxControlToolkit.HTMLEditor.ToolbarButton.ForeColorSelector ForeColorSelector = new AjaxControlToolkit.HTMLEditor.ToolbarButton.ForeColorSelector();
            TopToolbar.Buttons.Add(ForeColorSelector);
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.ForeColorClear());

            //文字背景色按钮
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.FixedBackColor());
            //文字背景色下来菜单
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.BackColorSelector());
            //取消文字背景色
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.BackColorClear());

            //清除格式
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.RemoveStyles());

            //文字字体
            AjaxControlToolkit.HTMLEditor.ToolbarButton.FontName fontName = new AjaxControlToolkit.HTMLEditor.ToolbarButton.FontName();
            TopToolbar.Buttons.Add(fontName);

            option.Value = "impact";
            option.Text = "Impact";
            options.Add(option);
            option = new AjaxControlToolkit.HTMLEditor.ToolbarButton.SelectOption();
            option.Value = "wingdings";
            option.Text = "WingDings";
            options.Add(option);

            //剪切
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.Cut());
            //复制
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.Copy());
            //粘贴
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.Paste());
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.PasteText());
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.PasteWord());

            //增加缩进量
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.IncreaseIndent());
            //减少缩进量
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.DecreaseIndent());

            //插入分割线
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.InsertHR());
            //插入超链接
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.InsertLink());
            //取消超链接
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.RemoveLink());

            //编号
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.OrderedList());
            //项目编号
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.BulletedList());

            //分段
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.Paragraph());
            
	     //文本左对齐
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.JustifyLeft());
            //文本右对齐
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.JustifyRight());
            //居中
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.JustifyCenter());
            //两端对齐
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.JustifyFull());
            //取消对齐
            TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.RemoveAlignment());

            //设计视图
            BottomToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.DesignMode());
            //HTML视图
            BottomToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.HtmlMode());
            //预览视图
            BottomToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.PreviewMode());

上面这些不论写在FillTopToolbar还是FillBottomToolbar都行，甚至两个一起写也可以（估计没这么BT的吧...）

不过一般习惯上还是FillTopToolbar里写编辑菜单，FillBottomToolbar里面放视图模式...

已经自定义好了编辑器，下面我们就要在页面里使用它了，打开我们的页面，在页面上注册我们钢材建立的命名空间，再在页面里添加就可以了

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="editor.aspx.cs" Inherits="editor" %>
<%@ Register Namespace="myhtmleditor" TagPrefix="myhtmleditor" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script type="text/javascript">
      function pageLoad() {
      }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server" />
        <myhtmleditor:myeditor ID="myeditor" runat="Server" Width="500px" Height="300px" />
    </div>
    </form>
</body>
</html>

恩，最后上图看下效果（我这里把菜单全加上了，可以根据自己需要选择有用的菜单就可以了）

就写这些吧，有什么不对的地方望大家指出。
