NET WebBrowser控件 - 获取活动的contextmenu

Question

我有WebBrowser控件，我想单击右键并出现上下文菜单获取该上下文菜单的句柄。

是可能的吗？

Answer 1

是的。

您可以参考下面的代码。

//this code assumes WebBrowser object(_webBrowser) is already initiated 
    //in class scope. 

    //this method is needed to execute when form is loaded. 
    //Register it to load event 
    private void Loaded(object sender, RoutedEventArgs e) 
    { 
     _webBrowser.LoadCompleted += _webBrowser_LoadCompleted; 
    } 

    private HTMLDocumentEvents2_Event _docEvent; 

    private void _webBrowser_LoadCompleted(object sender, NavigationEventArgs e) 
    { 
     if (_docEvent != null) 
     { 
      _docEvent.oncontextmenu -= new HTMLDocumentEvents2_oncontextmenuEventHandler(_docEvent_oncontextmenu); 
     } 
     if (_webBrowser.Document != null) 
     { 
      _docEvent = (HTMLDocumentEvents2_Event)_webBrowser.Document; 
      _docEvent.oncontextmenu += new HTMLDocumentEvents2_oncontextmenuEventHandler(_docEvent_oncontextmenu); 
     } 
    } 

    bool _docEvent_oncontextmenu(IHTMLEventObj pEvtObj) 
    { 
     //do something and determine you want whether context menu shows or not 
     //if you want to shows context menu, you'll need to return true. 
     return true; 
    }

如果你想显示自己的contextMenu代替。我这里贴的解决方案，对于一个WinForms WebBrowser控件的工作原理：
