Silverlight自定义二级菜单

PS需要补充的一个问题  下面图片中出现的跟目录1  加载了2次  是之前上传的时候忘记LeftMenu.xaml里面的这句代码删除了

<uc:TabDetail TRootStyle="{Binding RootStyle,ElementName=LeftMenuUC}" TTabDetailText="{Binding LeftMenuText,ElementName=LeftMenuUC}" TRootName="{Binding RootName,ElementName=LeftMenuUC}" TIResource="{Binding IResource,ElementName=LeftMenuUC}" TItemActualHeight="{Binding ItemActualHeight,ElementName=LeftMenuUC}"></uc:TabDetail>

删除这句代码  就会正常显示   目录  1  2  3  4
