我正在创建一个应用程序,我希望修复某些网格行和列,而其他人则调整大小以适应窗口。我的问题是我无法在Universal Apps中执行此操作。
在WPF中,解决方案很简单:
<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="50" /> <!-- This row is a fixed height -->
<RowDefinition Height="*" MinHeight="200" /> <!-- This row is resizeable, but has a minimum height -->
<RowDefinition Height="100" />
<RowDefinition Height="20" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="20" /> <!-- This column has a fixed width -->
<ColumnDefinition Width="*" MinWidth="300" /> <!-- These rows are resizeable, but have minimum widths -->
<ColumnDefinition Width="*" MinWidth="300" />
<ColumnDefinition Width="20" />
</Grid.ColumnDefinitions>
</Grid>
当我在UWP中尝试此操作时,具有固定大小的行和列会调整大小,而带有星号的其他行保持固定。我尝试在固定的行和列上添加星号并删除预先存在的行和列。我认为在UWP中它被颠倒了,但这严重搞砸了我的应用程序并使其变得更糟。
我的解决方案是在UWP中尝试以下内容:
<Grid x:Name="pageGrid"
Background="White">
<Grid.RowDefinitions>
<RowDefinition MaxHeight="20"
MinHeight="20"/>
<RowDefinition Height="*"/>
<RowDefinition MaxHeight="20"
MinHeight="20"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition MaxWidth="20"
MinWidth="20"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition MaxWidth="260"
MinWidth="260"/>
<ColumnDefinition MaxWidth="20"
MinWidth="20"/>
</Grid.ColumnDefinitions>
</Grid>
这里的想法是在我的控件周围有20个像素宽度的固定边距。在这些边缘内有两个盒子:一个具有固定的宽度和可调整的高度,另一个在两个方向上调整大小。
尽管如此,我再次遇到了同样的问题,即边距调整大小但是可调整大小的&#39;盒子没有。
实际上是否有办法在使用通用Windows平台的网格中拥有固定和可调整大小的行和列?到目前为止,我还没有找到证据。

此代码旨在将额外的行和列作为主控件周围的边距。这些应固定在20像素。当我运行代码时,边距伸展,中央框保持固定;这与我的意图相反:
