c# - 如何通过 XAML 手动将静态项目绑定(bind)到 SplitButton (mahapps)

Question

我如何手动添加例如 2 个项目(按钮)，其中第一个是通过 xaml 预选的？喜欢:

<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;
}

这是它在运行时的样子:
