如何优化全屏视图的窗口布局？ WPF

我有一个WPF窗口，主持一个简单的主页按钮布局，顶部一排按钮和一个视频源，但是当我最大化窗口。布局与标准视图不同步。如何优化全屏视图的窗口布局？ WPF

我试图通过设置图像元素stretch "fill"但顶部按钮排不看也均匀home键搬迁到屏幕的中心，不好看弥补一些布局

我的问题我该如何调整xaml布局属性以支持标准和最大化视图？

这是窗口的布局：

    <Grid>

     <Viewbox Grid.Row="1" Stretch="Uniform" HorizontalAlignment="Center"> 

      <Image x:Name="KinectVideo" Width="640" Height="250" Visibility="Visible" Stretch="Fill" /> 

     </Viewbox> 


     <Button x:Name="homeBtn" Content="" Width="50" Click="homeBtn_Click" Height="35" Margin="272,294,277,10" > 

      <Button.Background>
