设置孩子的高度或宽度为父控件相同在android

“match_parent”我有一个网页，其中包括一个网格，并在该网格内有一个地图。但我无法将网格大小设置为与网格大小相同。虽然我可以在代码中设置它设置孩子的高度或宽度为父控件相同在android

MyMap.Height = LayoutRoot.ActualHeight; 
MyMap.Width = LayoutRoot.ActualWidth;

但是我怎样才能在xaml中设置它。

<phone:PhoneApplicationPage 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone" 
    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone" 
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
    xmlns:maps="clr-namespace:Microsoft.Phone.Maps.Controls;assembly=Microsoft.Phone.Maps" 
    x:Class="MapSample.MainPage" 
    mc:Ignorable="d" 
    FontFamily="{StaticResource PhoneFontFamilyNormal}" 
    FontSize="{StaticResource PhoneFontSizeNormal}" 
    Foreground="{StaticResource PhoneForegroundBrush}" 
    SupportedOrientations="Portrait" Orientation="Portrait" 
    shell:SystemTray.IsVisible="True"> 

    <Grid x:Name="LayoutRoot" Background="Red"> 
     <maps:Map x:Name="MyMap" HorizontalAlignment="Left" VerticalAlignment="Top" Center="47.6097, -122.3331" ZoomLevel="10"/> 
    </Grid> 

</phone:PhoneApplicationPage>

应设置HorizontalAlignment和地图控件的VerticalAlignment到Stretch

<maps:Map x:Name="MyMap" 
      HorizontalAlignment="Stretch" 
      VerticalAlignment="Stretch" 
      Center="47.6097, -122.3331" 
      ZoomLevel="10" />
