.NET WebBrowser控件-获取活动上下文菜单

问题描述

| 我有Webbrowser控件，我想单击右键时出现上下文菜单以获取该上下文菜单的句柄。 那可能吗？     

解决方法

        是。 您可以参考以下代码。

    //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;
    }
