Excel AddIn，c＃，。net 4.0，windows 7，功能区 我的插件有一个功能区标签，几个功能区按钮， 单击一个功能区时，插件将发送多个Web服务调用，弹出一个窗口，提供tab，treeview，gridview等数据。 树视图中的数据，gridview是从Web服务调用填充的。 直到昨天，所有人都为特定的最终用户工作 当他点击按钮时，窗口似乎显示出来，但它有点落后于Excel，无法集中注意力。它也是空白的，没有标签，树视图，gridview等。 我验证了所有Web服务调用都正确返回。 用户具有Windows 7，Excel 2010（32位）。 我不知道是什么原因引起的。请帮忙。 这是我的WPF窗口。谢谢

答案 0 :(得分：1)
我知道这已经过时了 - 但我们偶然发现了我们支持的旧版Office加载项 - 其中一个用户显然遇到了同样的问题。
我们做了一些挖掘工作，偶然发现了这个类似的SO帖子：Blank WPF child windows on Windows 10
看起来有两种选择：
指示用户更新/修复错误的视频卡驱动程序。
将强制内容重新绘制的代码放入正确的时刻（即InvalidateVisual是不够的，请参阅链接的问题＆＃39; s答案了解更多信息）。
