色帶窗口上的多餘空格

Question

我正在關注教程here。 這裏是我的XAML代碼：

<Window x:Class="warm6.MainWindow" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     Title="MainWindow" Height="350" Width="525"> 
    <Grid> 
     <Grid.RowDefinitions> 
      <RowDefinition Height="Auto"/> 
      <RowDefinition Height="*" /> 
     </Grid.RowDefinitions> 

     <Ribbon x:Name="RibbonWin"> 
      <!-- help icon on the right side --> 
      <Ribbon.HelpPaneContentTemplate> 
       <DataTemplate> 
        <RibbonButton SmallImageSource="images\help.png" /> 
       </DataTemplate> 
      </Ribbon.HelpPaneContentTemplate> 

      <Ribbon.ApplicationMenu> 
       <RibbonApplicationMenu SmallImageSource="images\window.png"> 
        <RibbonApplicationMenuItem Header="Open" ToolTipTitle="Application Menu" 
               ImageSource="images\window2.png"/> 
        <RibbonApplicationMenuItem Header="_Save" 
               ImageSource="images\save.png"/> 
        <RibbonSeparator/> 
        <RibbonApplicationMenuItem Header="_Close" ImageSource="images\close.png"/> 
        <RibbonApplicationMenu.AuxiliaryPaneContent> 
         <Grid> 
          <Grid.RowDefinitions> 
           <RowDefinition Height="Auto" /> 
           <RowDefinition Height="5" /> 
           <RowDefinition Height="*" /> 
          </Grid.RowDefinitions> 
          <RibbonSeparator Grid.Row="0" Label="Recently Templates" /> 
         </Grid> 
        </RibbonApplicationMenu.AuxiliaryPaneContent> 
       </RibbonApplicationMenu> 
      </Ribbon.ApplicationMenu> 

      <RibbonTab> 

      </RibbonTab> 
     </Ribbon> 

    </Grid> 
</Window>
