WPF中Ribbon控件中的Ribbon按钮未正确对齐

我正在为我的应用程序创建Ribbon控件，我已经为此编写了大部分代码。我面临的唯一问题是，我添加到选项卡的功能区按钮在选项卡中没有正确对齐。正如您在屏幕截图中所看到的，按钮与选项卡底部对齐。如何将这些按钮置于顶部，使其可见

这就是我的应用程序的样子

下面是XAML代码

<UserControl x:Class="SongPurifier.UserControls.RibbonControl"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         xmlns:ribbon="http://schemas.microsoft.com/winfx/2006/xaml/presentation/ribbon"
        >
<Grid>
    <ribbon:Ribbon x:Name="ribbon" VerticalAlignment="Top">
        <ribbon:RibbonTab Header="Home">
            <ribbon:RibbonSplitButton  
                Label="Open" 
                LargeImageSource="/Images/Folder Open.png"
                Command="{Binding OpenFolderCommand}">
            </ribbon:RibbonSplitButton>
        </ribbon:RibbonTab>

        <ribbon:RibbonTab Header="Edit" >
            <ribbon:RibbonButton Label="Replace String" 
                                 LargeImageSource="/Images/Find Replace.png"
                                 Command="{Binding EditSongInfoCommand}"
                                 >
            </ribbon:RibbonButton >

            <ribbon:RibbonButton Label="Update Song Info"
                                 LargeImageSource="/Images/Update.png"
                                 Command="{Binding UpdateSongInfoCommand}"
                                 >
            </ribbon:RibbonButton>
        </ribbon:RibbonTab>
        <ribbon:RibbonTab Header="Update" >
            <ribbon:RibbonButton 
                Label="Check for Update" >

            </ribbon:RibbonButton>
        </ribbon:RibbonTab>
    </ribbon:Ribbon>
</Grid>

萨钦： 将功能区按钮放置在RibbonGroup中

<my:RibbonTab Header="Home">
    <my:RibbonGroup Header="File">
        <ribbon:RibbonSplitButton  
            Label="Open" 
            LargeImageSource="/Images/Folder Open.png"
            Command="{Binding OpenFolderCommand}">
        </ribbon:RibbonSplitButton>
    </my:RibbonGroup>
</my:RibbonTab>

是的，这很有效！根据我的要求，我认为我不需要在RibbongGroup中添加按钮，但现在在这个ans之后，看看MSFT给出的示例，我认为你必须这样做。是的，这很有效！根据我的要求，我认为我不需要在RibbongGroup中添加按钮，但现在在这个ans之后，看看MSFT给出的示例，我认为您必须这样做。
