我有一个Silverlight 4应用程序。此应用程序使用Accordian。我想尝试这个手风琴。为了做到这一点，我有以下内容：

我希望将整个Accordian风格定义为可重复使用的模板。我需要使用我在ControlTemplate元素中创建的样式。我的挑战是，我不知道如何让我的Style使用ControlTemplates。有人可以展示如何将我的ControlTemplate集成到Style中吗？谢谢！

您只需要以样式设置控件模板，例如
<Style x:Key="myItemStyle" TargetType="toolkit:AccordionItem">
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate>
<TextBlock Text="Text goes here" />
</DataTemplate>
</Setter.Value>
</Setter>
**<Setter Property="Template" Value="{StaticResource myAccordianItem}"/>**
</Style>
<Style x:Key="myAccordionButtonStyle" TargetType="toolkit:AccordionButton">
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="Background" Value="White"/>
<Setter Property="HorizontalAlignment" Value="Stretch"/>
<Setter Property="VerticalAlignment" Value="Stretch"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="IsTabStop" Value="True"/>
<Setter Property="TabNavigation" Value="Once"/>
**<Setter Property="Template" Value="{StaticResource myAccordianHeader}"/>**
</Style>
并在Accordion控件中，指定上面的这些样式
<toolkit:Accordion x:Name="myAccordian" ItemsSource="{Binding MyItems}" ItemContainerStyle="{StaticResource myItemStyle}" AccordionButtonStyle="{StaticResource myAccordionButtonStyle}" />
我希望这会有所帮助。 ：）
