wpf 绑定 material 设计对话框宽度,小于或超过 window 宽度
wpf binding material design dialog width, is either smaller or exceed window width
我想将对话框的宽度设置为覆盖整个父页面,在本例中是 UserControl,因此是 window。为此,我尝试将 material 设计对话框的宽度绑定到 UserControl 的 ActualWidth
。
只要 window 没有最大化,它就可以正常工作。
当它最大化时,对话框的宽度小于 UserControl 之一:
我尝试将 UserControl 的宽度绑定到 Window 的 ActualWidth
(Width="{Binding ActualWidth, ElementName=win}"
),但最糟糕的是对话框超过了 window :
我缺少什么?

我怀疑如果 window 除了被最大化之外还被放置在屏幕边缘旁边,您会看到类似的问题。原因是因为 DialogHost 控件包含一个 DialogMargin 属性,所有边默认为 35。出于您的目的,您可能希望将其设置为 0。
