禁用WebBrowser上下文菜單

Question

如何禁用WPF WebBrowser-Control的standard-context菜單？

Answer 1

使用mshtml;

    private mshtml.HTMLDocumentEvents2_Event documentEvents;

在構造函數或xaml中設置您的LoadComplete事件：

   webBrowser.LoadCompleted += webBrowser_LoadCompleted;

然后在該方法中創建新的Webbrowser文檔對象，並查看可用屬性並創建新事件，如下所示：

private void webBrowser_LoadCompleted(object sender, NavigationEventArgs e)
{
    documentEvents = (HTMLDocumentEvents2_Event)webBrowserChat.Document; // this will access the events properties as needed
    documentEvents.oncontextmenu += webBrowserChat_ContextMenuOpening;
}

private bool webBrowserChat_ContextMenuOpening(IHTMLEventObj pEvtObj)
{
    return false; // ContextMenu wont open
    // return true;  ContextMenu will open
    // Here you can create your custom contextmenu or whatever you want
}
