Powershell WPF XAML折叠RowDefinition高度或设置为零的事件
问题描述:
我正在寻找的最终效果是“消失”行“1”,又名:从顶部开始的第二行,以便Text1向下扩展到区域中如果第1行不存在。Powershell WPF XAML折叠RowDefinition高度或设置为零的事件
这是我试图完成的模型。前2行和列几乎完全相同。
如果我将此XAML插入到VS2017社区,并将行高设置为0,则可以使用。谷歌搜索了几天后,我还没有想出一个解决方案。
我根本不知道C#。
平台: 的Windows 7 //辣妹V5
不久将视窗10 //辣妹V5
理想情况下,我想开始使用它关闭,并打开它的事件。

谢谢你的期待。
答
这是因为它不是$WPFGrid.RowDefinition
而是$WPFGrid.RowDefinitions
,最后是s
。
我删除Visibility
的方法,因为它没有与RowDefinitions
实现并由<RowDefinition Height="0" />
改变<RowDefinition Height="40" />
给行隐形启动窗口。
此代码工作

谢谢马努!我“发誓”我试过这个。 (显然不是)。 – Steve
