Web浏览器控件在WPF

Question

我的目标是类似于this question
但我仍没有得到回答我的问题

所以，我需要做所见即所得的HTML编辑支持的应用程序设计和生成报告模板。和上面的问题一样，我在WPF中使用了WebBrowser控件。最大的问题是WPF web浏览器始终将designMode设置为后置null到HTML的身体。所以我把WinForm WebBrowser放到我的应用程序中。并设置或获取HTML文档从WebBrowser处理是非常困难的。

问：

1. 有什么办法使这个（使用HTML编辑器WebBrowser控件）发生使用WPF没有改变WinForm的？
2. 或者，如果没有。有任何解决方法，文章，代码或任何不论使所见即所得的HTML编辑器与可视化编辑器？

UPDATE：
我对MVVM目的，这些2附加属性。所以我可以使用HTMLSource获取/设置HTML，并在启动应用程序时设置设计模式。

IsDesignMode

public static readonly DependencyProperty IsDesignModeProperty = 
    DependencyProperty.RegisterAttached("IsDesignMode", typeof (Boolean), typeof (WebBrowserHelper), 
             new UIPropertyMetadata(false, IsDesignModePropertyChanged)); 

public static Boolean GetIsDesignMode(DependencyObject obj) 
{ 
    return (Boolean)obj.GetValue(IsDesignModeProperty); 
} 

public static void SetIsDesignMode(DependencyObject obj, Boolean value) 
{ 
    obj.SetValue(IsDesignModeProperty, value); 
} 

public static void IsDesignModePropertyChanged(DependencyObject obj, DependencyPropertyChangedEventArgs args) 
{ 
    WebBrowser browser = obj as WebBrowser; 
    if (browser != null) 
    { 
     Boolean designMode = (Boolean) args.NewValue; 
     if(designMode) 
     { 
      browser.LoadCompleted += (s, e) => 
      { 
       var htmlDoc = (s as WebBrowser).Document as IHTMLDocument2; 
       htmlDoc.body.setAttribute("contenteditable", "true"); 
       htmlDoc.designMode = "On"; 
      }; 
     } 
     else 
     { 
      browser.LoadCompleted += (s, e) => 
      { 
       var htmlDoc = (s as WebBrowser).Document as IHTMLDocument2; 
       htmlDoc.body.setAttribute("contenteditable", "false"); 
       htmlDoc.designMode = "Off"; 
      }; 
     } 
    } 
} 

HTMLSource

public static readonly DependencyProperty HTMLSourceProperty = 
    DependencyProperty.RegisterAttached("HTMLSource", typeof (String), typeof (WebBrowserHelper), 
             new UIPropertyMetadata(null, HTMLSourcePropertyChanged)); 

public static String GetHTMLSource(DependencyObject obj) 
{ 
    return (String)obj.GetValue(HTMLSourceProperty); 
} 

public static void SetHTMLSource(DependencyObject obj, String value) 
{ 
    obj.SetValue(HTMLSourceProperty, value); 
} 

public static void HTMLSourcePropertyChanged(DependencyObject o, DependencyPropertyChangedEventArgs args) 
{ 
    WebBrowser browser = o as WebBrowser; 
    if (browser != null) 
    { 
     browser.NavigateToString(args.NewValue as String); 
    } 
}

Answer 1

你尝试一些开放源码而不是WInForms的替代品？

我觉得这个人有良好的互动，并能处理JavaScript回调到WPF了。

Answer 2

我写了一个很简单的WPF应用程序，使用嵌入的资源为HTML和包含下面的代码：

Stream s = GetType().Assembly.GetManifestResourceStream("WpfApplication5.HTMLPage1.htm"); 
    webBrowser1.NavigateToStream(s); 
    IHTMLDocument2 doc = webBrowser1.Document as IHTMLDocument2; 
    doc.designMode = "On"; 

代码和预期一样的，我可以编辑网页的内容 - 按照您的建议将其设置为designMode后，它不会被清空。也许从上面的代码开始，并检查你可以得到它的工作。
