今天我们来研究下怎么美化Accordion，首先没有安装Toolkit 的同学请下载安装；
下载地址：http://www.codeplex.com/Silverlight/
先上最后效果图吧：
1. 先在画布上画一个（或在代码里面写一个） AccordionItem ， 注意不是 Accordion；
为什么是 AccordionItem 呢，因为Accordion的样式基本都在 AccordionItem 里面；
<layoutToolkit:AccordionItem Content="Content" Header="Header"></layoutToolkit:AccordionItem>
2. 编辑副本》 创建一个style；
3. 编辑模板，发现这里面啥都没有，就两个对象，被骗了？？
4. 继续往下创建副本，藏得够深的！！！
后面带一个小对勾的是控件中的控件 ，（这里把他的高度调到30，默认的太小）
5. 如果说Accordion的样式基本都在 AccordionItem 里面；
那么 AccordionItem 的样式基本都在 AccordionButton 里面；
6 . 修改AccordionButton 的style，得到想要的效果；
回到页面敲入代码：
<layoutToolkit:Accordion Margin="8,217,0,17" VerticalAlignment="Stretch" Width="257" BorderThickness="0" Background="{StaticResource CD}">
<layoutToolkit:AccordionItem Content="Content1" Header="Header1" Style="{StaticResource MyAccordionItemStyle}" BorderThickness="0" RenderTransformOrigin="0.5,0.5" UseLayoutRounding="False" d:LayoutRounding="Auto" />
<layoutToolkit:AccordionItem Content="Content2" Header="Header2" Style="{StaticResource MyAccordionItemStyle}" />
<layoutToolkit:AccordionItem Content="Content3" Header="Header3" Style="{StaticResource MyAccordionItemStyle}" />
</layoutToolkit:Accordion>
搞定！
这里其实只是初步搞定了 Accordion， 像一些细节，
比如鼠标动作的样式变化都还没有做；
像 Content 只有文字肯定是不能满足要求的，应该是链接那种才比较合理；
至少找到地方改了，回头再优化吧。。。。

说实话微软太BT了，通过鼠标操作生成这些个代码，一层一层的，还有很多类似于 0.000002，34444，33 这种莫名其妙的数字子类的；
头学两天以为这些都像css一样要自己写，吓蒙了~~~原来是用blend搞出来的。
