WPF窗口显示空白

Excel插件，C＃，.NET 4.0，Windows 7，function区我的插件有一个function区选项卡，几个function区button，当一个function区被点击，插件会发送几个Web服务调用，一个窗口将popup提供数据标签，树视图，gridview等数据在树视图中，gridview从Web服务调用填充。 所有工作的特定最终用户，直到昨天当他点击button，窗口似乎显示出来，但它是一种背后的Excel，不能集中。 也没有选项卡，树形视图，GridView等，我确认所有的Web服务调用返回正常。 用户有Windows 7，Excel 2010（32位）。 我不知道是什么原因造成的。 请帮忙。 这是我的WPF窗口。 谢谢

Answer 1

我知道这是旧的 – 但我们偶然发现了一个我们支持的传统Office插件，其中一个用户显然遇到了同样的问题。

我们做了一些挖掘，并偶然发现了这个类似的SOpost： Windows 10上的空白WPF子窗口

看起来有两个select：

1. 指导用户更新/修复其不良video卡驱动程序。

2. 对代码进行破解， 强制内容在正确的时刻重绘（即InvalidateVisual是不够的，请参阅链接的问题的答案以获取更多信息）。
