为什么我的UWP应用程序中的表单/页面在运行时被截断（不反映设计时的大小）？

在我的UWP应用程序的设计阶段，我已经为我想要的一切留出了足够的空间（顶部有六个按钮和一个文本块，最终将包含更多的文本）：

请注意，文本块位于页面底部

在运行时，顶部的TextBlock被严重截断，表单/页面底部的所有TextBlock根本不显示，可能是出于相同的原因：

如果这是按设计（由微软，也就是说，不是由我）进行的，我需要做什么才能符合公认的创建运行时完全可见的布局的方法

更新 在最大化窗口时，顶部看起来不错，但我的“标签”（文本块）不可见：

虽然你看不见，但在底部有空间放置标签/文本块；我将地图的上下边距设置为50:margin=“0,50,0,50”

更新2 根据Roy Li的要求，这是代码。首先，XAML：

该行为的原因是您正在为文本块的

边距

属性设置一个绝对值。该值太大，因此这些文本块的位置超出了应用程序的可见布局。换句话说，布局是不自适应的

以下是更正布局的简单方法：

 <Grid x:Name="grd">
   <!--Add row definitions-->
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>
    <!--top area controls-->
    <Button x:Name="btnLoadMap" Content="Load Map" Margin="20,12,50,0" VerticalAlignment="Top" Click="btnLoadMap_Click" />
    <Button   x:Name="btnCre8NewMap" Content="Create New Map" Margin="140,12,50,0" VerticalAlignment="Top" Click="btnCre8NewMap_Click"/>
    <Button   x:Name="btnAddLoc" Content="Add Location" Margin="280,12,50,50" VerticalAlignment="Top" Click="btnAddLoc_Click"/>
    <Button   x:Name="btnRemoveLoc" Content="Remove Location" Margin="400,12,0,0" VerticalAlignment="Top" Click="btnRemoveLoc_Click"/>
    <Button    x:Name="btnPrint" Content="Print Map" Margin="570,12,0,0" VerticalAlignment="Top" Click="btnPrint_Click"/>
    <Button   x:Name="btnSave" Content="Save Map Image" Margin="670,12,0,0" VerticalAlignment="Top" Click="btnSave_Click"/>
    
    <TextBlock x:Name="txtBlckMapType" HorizontalAlignment="Left" Margin="800,16,0,0" Text="Map Style: " TextWrapping="Wrap" VerticalAlignment="Top" FontWeight="Bold"/>
    <TextBlock x:Name="txtBlckCurrentMap" HorizontalAlignment="Left" Margin="1040,16,0,0" Text="Current Map: " TextWrapping="Wrap" VerticalAlignment="Top" FontWeight="Bold"/>
    <ComboBox  x:Name="cmbxMaptype" Margin="876,12,0,0" Width="160" DropDownClosed="cmbxMaptype_DropDownClosed"/>
     <!--map controls-->
    <Maps:MapControl Grid.Row="1" x:Name="MapControl1" Style="Terrain"  />
    <!--bottom area controls-->
    <TextBlock x:Name="txtBlckLegend" HorizontalAlignment="Left"   Grid.Row="2" Margin="20,12,0,0" Text="LEGEND:" TextWrapping="Wrap" VerticalAlignment="Top" FontWeight="Bold" FontSize="14"/>
    <TextBlock x:Name="txtBlckRed" HorizontalAlignment="Left"  Grid.Row="2" Margin="90,12,0,0" Text="Red markers " TextWrapping="Wrap" VerticalAlignment="Top"/>
    <TextBlock x:Name="txtBlckOrange" HorizontalAlignment="Left"  Grid.Row="2" Margin="193,12,0,0" Text="Orange markers " TextWrapping="Wrap" VerticalAlignment="Top"/>
    <TextBlock x:Name="txtBlckYellow" HorizontalAlignment="Left"  Grid.Row="2" Margin="296,12,0,0" Text="Yellow markers " TextWrapping="Wrap" VerticalAlignment="Top"/>
    <TextBlock x:Name="txtBlckGreen" HorizontalAlignment="Left"  Grid.Row="2" Margin="399,12,0,0" Text="Green markers " TextWrapping="Wrap" VerticalAlignment="Top"/>
    <TextBlock x:Name="txtBlckBlue" HorizontalAlignment="Left"  Grid.Row="2" Margin="502,12,0,0" Text="Blue markers " TextWrapping="Wrap" VerticalAlignment="Top"/>
    <TextBlock x:Name="txtBlckIndigo" HorizontalAlignment="Left"  Grid.Row="2" Margin="605,12,0,0" Text="Indigo markers " TextWrapping="Wrap" VerticalAlignment="Top"/>
    <TextBlock x:Name="txtBlckViolet" HorizontalAlignment="Left"  Grid.Row="2" Margin="708,12,0,0" Text="Violet markers " TextWrapping="Wrap" VerticalAlignment="Top"/>
    <TextBlock x:Name="txtBlckBlack" HorizontalAlignment="Left"  Grid.Row="2" Margin="811,12,0,0" Text="Black markers" TextWrapping="Wrap" VerticalAlignment="Top"/>
    <TextBlock x:Name="txtBlckWhite" HorizontalAlignment="Left"  Grid.Row="2" Margin="914,12,0,0" Text="White markers " TextWrapping="Wrap" VerticalAlignment="Top"/>
    <TextBlock x:Name="txtBlckGray" HorizontalAlignment="Left"  Grid.Row="2" Margin="1017,12,0,0" Text="Gray markers " TextWrapping="Wrap" VerticalAlignment="Top"/>
    
</Grid>

我所做的是将网格划分为三行，并确保控件放置在正确的行中。我为文本块添加了

Grid.Row=“2”

，这样这些文本块将显示在底部的最后一行

现在，即使应用程序未最大化，文本块也将始终显示在底部

如果单击最大化按钮，布局是否会正确显示在surface book中？如果是，那么问题应该是应用程序窗口的大小小于3000*2000，并且您没有使布局自适应-。请查看我的更新；即使在max（我希望默认情况下是这样），我在页面底部的标签（文本块）也是不可见的。请检查地图控件是否覆盖在底部？您只需暂时删除地图控件并以最大值显示应用程序即可确认。您也可以选择在此处共享您的代码片段，以便我们检查。好的，我将添加代码；我想你主要指的是xaml，对吧？是的，这就是我需要的代码片段
