我正在制作一个应用程序,我希望某些网格行和列是固定的,而其他的调整大小以适应窗口。我的问题是,我无法在通用应用程序中做到这一点

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>
<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>

在UWP中尝试此操作时,大小固定的行和列会调整大小,而其他带星号的行和列则保持不变。我试着在固定的行和列上加上星号,然后删除已有的行和列。我原以为在UWP中是相反的,但这严重扰乱了我的应用程序,使情况变得更糟

我的解决方案是在UWP中尝试以下操作:

<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>
<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像素宽的固定边距。在这些页边距中有两个框:一个框具有固定的宽度和可调整的高度,另一个框在两个方向上调整大小

尽管如此,我还是遇到了同样的问题,边距调整了大小,但“可调整大小”框没有

是否有一种方法可以使用通用Windows平台在网格中固定和调整大小的行和列?到目前为止,我还没有找到这方面的证据。

此代码旨在在主控件周围有额外的行和列作为边距。这些应该固定在20像素。当我运行代码时,边距会拉伸,中央框保持固定;这与我的意图相反:


(调整窗口大小时,黑色轮廓区域保持不变,而边距拉伸以适应窗口。)

您的主网格固定为800 x 450 px。如果删除该限制,网格将适当拉伸

更新代码:

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"
      MinWidth="800"
      MinHeight="450">
    <Grid x:Name="pageGrid"
...


查看您的网格定义,它似乎是有序的。就网格的工作方式而言,UWP与WPF的行为方式相同,因此不应存在任何问题/差异。我使用您的网格声明创建了一个测试,它似乎像预期的那样扩展。你能发布你的完整代码吗?@AlexDrenea complete code添加到问题中那么页面有什么问题?我看起来/伸展得很好。边框是固定的,“屏幕”是放大的,侧面的按钮是固定的。这对我不起作用…?这也是我看到的。那么预期的结果是什么?如果需要让屏幕延伸整个区域,请删除主栅格上的宽度/高度值。
