我开发一个WPF应用程序,允许两个端点在一个视频聊天连接从WPF消失。我已经被设计在XAML设计的UI在过去的两个月,一切正常,当我跑它没有显示一切等直到昨天,对于完全没有任何明显原因的应用程序。 UI的一些部分的代码时在另一台笔记本电脑上运行只是不出来了。我坚持事实上,它之前已经工作,现在不再工作了。我也没有改变代码中可能与UI的那部分有关的任何东西,也没有在xaml中做任何改变。UI元素在运行时
我没有检查过,我从来没有搞错代码隐藏的任何可见性参数,所以我没有看到任何应用程序的行为突然改变的原因。
有没有人有一个想法,为什么会发生这种情况?
这里是XAML:

在这里,它的外观时,应用程序在笔记本电脑上运行就像一个截图:
你显然有一个布局的问题。所有的布局都使用诸如“Margin =”26,24,1165,835“'这样的东西不够充分,可能会导致各种不良行为。我建议您删除所有边距并使用正确的[WPF布局](http://www.codeproject.com/Articles/30904/WPF-Layouts-A-Visual-QuickStart)技术。 –
我同意Highcore。许多(All?)宽度,高度,边距都是硬编码的。如果两台电脑的窗户大小不一样,可能会变坏。尝试使两台电脑上的两个窗口具有相同的大小,并检查您是否仍然看到相同的东西 –
谢谢您的有用输入。我对WPF世界很陌生;你能解释一下使用边距和使用Canvas的区别吗?会使用画布帮我吗? – ArthurT
