一种方法是添加一个
列表框作为拆分按钮的内容
<ControlTemplate x:Key="SplitButtonTemplate" TargetType="xctk:SplitButton">
<Grid x:Name="MainGrid" SnapsToDevicePixels="True">
<xctk:ButtonChrome x:Name="ControlChrome" Background="{TemplateBinding Background}"

Content="{TemplateBinding Content}"
ContentTemplate="{TemplateBinding ContentTemplate}"

HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
RecognizesAccessKey="true" />
</Button>
<ToggleButton x:Name="PART_ToggleButton"
Grid.Column="1"

IsChecked="{Binding IsOpen, RelativeSource={RelativeSource TemplatedParent}, Mode=TwoWay}">
<ToggleButton.Template>
<ControlTemplate TargetType="ToggleButton">

<Style TargetType="xctk:SplitButton">

您必须根据需要添加自定义代码以获得所需的确切行为，但以下是一个示例：
<xctk:SplitButton x:Name="btnSplit" Content="Select a product...">
<xctk:SplitButton.DropDownContent>
<ListBox ItemsSource="..."
SelectionChanged="ListBox_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding ProductName}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</xctk:SplitButton.DropDownContent>
</xctk:SplitButton>
private void ListBox_SelectionChanged(object sender, System.Windows.Controls.SelectionChangedEventArgs e)
{
ListBox content = (ListBox)sender;
btnSplit.Content = ((DataRowView)content.SelectedItem)["ProductName"].ToString();
btnSplit.IsOpen = false;
}
私有无效列表框\u选择已更改（对象发件人，System.Windows.Controls.SelectionChangedEventArgs e）
{
列表框内容=（列表框）发送方；
btnSplit.Content=（（DataRowView）Content.SelectedItem）[“ProductName”].ToString（）；
btnSplit.IsOpen=false；
}
