XAML矩形不扩大

我有一个横向扩展就好矩形，而不是垂直方向：XAML矩形不扩大

<Grid x:Name="MainDisplay" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Grid.Column="0" Grid.Row="0"> 
    <Grid.ColumnDefinitions> 
     <ColumnDefinition Width="*" /> 
     <ColumnDefinition Width="10" /> 
    </Grid.ColumnDefinitions> 
    <Grid.RowDefinitions> 
     <RowDefinition Height="*" /> 
     <RowDefinition Height="10" /> 
    </Grid.RowDefinitions> 
    <Viewbox MinWidth="400" MinHeight="400" x:Name="Scenario4ImageContainer" Stretch="Fill" Grid.Column="0" Grid.Row="0" VerticalAlignment="Stretch"> 
     <Rectangle MinWidth="400" MinHeight="400" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Fill="Blue"/> 
    </Viewbox>

当我minHeight属性设置为700它占用了所有的屏幕空间，但我想利用尽管它可以得到很多空间。

而且这种外网坐这个母网格内：

<Grid x:Name="Output" Background="#1D1D1D" Margin="0,2,0,-2" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> 
    <Grid.ColumnDefinitions> 
     <ColumnDefinition Width="*"/> 
     <ColumnDefinition Width="300"/> 
    </Grid.ColumnDefinitions> 
    <Grid.RowDefinitions> 
     <RowDefinition Height="*" /> 
     <RowDefinition Height="*" /> 
    </Grid.RowDefinitions>

我已经尝试了您发布的XAML和Rectangle扩大就好了。限制它的唯一方法是定义两行相等高度的外部Grid。尝试使第二行变窄，您将看到Rectangle展开：

<Grid x:Name="Output" Background="#1D1D1D" Margin="0,2,0,-2" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> 
    <Grid.ColumnDefinitions> 
     <ColumnDefinition Width="*"/> 
     <ColumnDefinition Width="300"/> 
    </Grid.ColumnDefinitions> 
    <Grid.RowDefinitions> 
     <RowDefinition Height="*" /> 
     <RowDefinition Height="100" /> 
    </Grid.RowDefinitions> 
    <Grid x:Name="MainDisplay" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Grid.Column="0" Grid.Row="0"> 
     <Grid.ColumnDefinitions> 
      <ColumnDefinition Width="*" /> 
      <ColumnDefinition Width="10" /> 
     </Grid.ColumnDefinitions> 
     <Grid.RowDefinitions> 
      <RowDefinition Height="*" /> 
      <RowDefinition Height="10" /> 
     </Grid.RowDefinitions> 
     <Viewbox MinWidth="400" MinHeight="400" x:Name="Scenario4ImageContainer" Stretch="Fill" Grid.Column="0" Grid.Row="0" VerticalAlignment="Stretch"> 
      <Rectangle MinWidth="400" MinHeight="400" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Fill="Blue"/> 
     </Viewbox> 
    </Grid> 
</Grid>
