C#WPF在窗口上显示带有AllowTransparency ="true"的WebBrowser不会显示

Question

我正在显示一个带有WebBrowser控件的窗口.我希望窗户是无框架的,所以我设置了WindowStyle ="无"这样可行但是在窗口周围显示彩色边框.Allowstransparency ="true"删除此项但不再显示WebBrowser(按钮是)

我找到了http://www.neowin.net/forum/topic/646970-c%23-wpf-window-with-transparency-makes-windowsformshost-disappear/但我无法让它工作(SetWindowsLong参数错误)

我知道这是一个古老的问题,但今天我遇到了完全相同的问题,我用它解决了

ResizeMode="NoResize"

代替

Allowstransparency="true"

ResizeMode也会删除annoing边框,并且不会影响WebBrowser控件.在这种情况下似乎是解决问题的最简单方法:)

它不能通过WPF技巧工作,因为WebBrowser控件实际上不是WPF控件.它是一个包装的ActiveX IE Web浏览器控件,不由WPF呈现.

也许您的问题与此帖子从WebBrowser控件中删除边框有关.

老实说,如果可能的话,试着放弃这个糟糕的WebControl并使用别的东西.有适当的WPF支持的免费替代品,例如Awesomium.NET,CefSharp或CefGlue.NET(均基于Chromium).
