Question

为什么我的网格没有覆盖所有屏幕，我该如何解决？在设计师看来它应该覆盖屏幕的所有宽度，但实际上留下了很大的空间。

 <Grid Background="GreenYellow">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />

    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="200"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition/>
    </Grid.RowDefinitions>


</Grid>

这段代码只是一个剪辑，但即使是孩子们的空间也是不同的尺寸。

修改1：

根据路易斯C.回答我得到了相同的结果左边的空白空间：

我找到了一个奇怪的解决方法来实现我想要的目标：

 <Grid  Background="Yellow">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="200"/>
        <RowDefinition Height="*"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>

    <Grid Grid.Row="0">
        <TextBlock Text="This is a very large text that only is used to strech all the childrens to the infinite. This is a very large text that only is used to strech all the childrens to the infinite. This is a very large text that only is used to strech all the childrens to the infinite. This is a very large text that only is used to strech all the childrens to the infinite. This is a very large text that only is used to strech all the childrens to the infinite" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
        <Button Content="Black" Background="Black" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
    </Grid>


    <Button Grid.Row="1" Content="Black" Background="Gray" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
    <Button Grid.Row="2" Content="Black" Background="Blue" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />

</Grid>

结果是：

仍然是解决问题的一种非常奇怪的方式。

如您所见，我在GridView上使用SplitView，在SplitViewContent内的Frame上加载Pages（就像上面提到的问题一样）。使用TextBlock作为孩子的其他页面覆盖了我想要的整个屏幕。 SplitView的代码是：

您只需删除没有高度的“RowDefinition”并将“Auto”行更改为“*”。

这样的事情：

<Grid Background="GreenYellow">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="200"/>
        <RowDefinition Height="*"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>

    <Button Grid.Row="0" Content="Black" Background="Black" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
    <Button Grid.Row="1" Content="Black" Background="Gray" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
    <Button Grid.Row="2" Content="Black" Background="Blue" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />

</Grid>
