如何通过XAML手动将静态项绑定到SplitButton（mahapps）

Question

如何手动添加例如2个项目（按钮），第一个项目是通过xaml预先选择的？像：

<controls:SplitButton SelectedIndex="0">
    <controls:SplitButton.Items>
        <Button Content="Button 1"/>
        <Button Content="Button 2"/>
    </controls:SplitButton.Items>
</controls:SplitButton>

Documentation告诉我使用ItemsSource Binding，但没有背后的代码示例。

这是XAML：

<controls:SplitButton x:Name="splitButton" 
        SelectedIndex="1" 
        HorizontalAlignment="Left" 
        VerticalAlignment="Top" 
        Grid.Column="1">
    <controls:SplitButton.ItemTemplate>
        <DataTemplate>
            <Grid>
                <TextBlock HorizontalAlignment="Left" 
                        TextWrapping="Wrap" 
                        Text="{Binding Text}" 
                        VerticalAlignment="Top"/>
            </Grid>
        </DataTemplate>
    </controls:SplitButton.ItemTemplate>
</controls:SplitButton>

这是背后的代码：

class SplitButtonItem
{
    public string Text { get; set; }
}

public MainWindow()
{
    InitializeComponent();

    var button1 = new SplitButtonItem() { Text = "Item 01", };
    var button2 = new SplitButtonItem() { Text = "Item 02", };
    var buttonList = new List<SplitButtonItem>() 
    {
        button1, 
        button2,
    };
    splitButton.ItemsSource = buttonList;
}

这是它在运行时的看法：

您可以使用ItemsSource和一个可枚举的对象，并且不指定DisplayMemberPath。

<controls:SplitButton HorizontalContentAlignment="Left"
                        HorizontalAlignment="Center"
                        VerticalContentAlignment="Center"
                        Width="120"
                        VerticalAlignment="Top">
    <controls:SplitButton.ItemsSource>
        <x:Array Type="system:String">
            <system:String>Label 1</system:String>
            <system:String>Another one</system:String>
            <system:String>Works now</system:String>
        </x:Array>
    </controls:SplitButton.ItemsSource>
</controls:SplitButton>
