Listpicker在ListBox中显示不了下拉菜单

大家好，小弟有个问题。 Listpicker在ListBox中显示不了下拉菜单，在<grid>中就能显示。如果显示怎样才能在显示的情况下不遮挡下放的控件呀？谢谢大家帮忙解决下！！拜托 --------------------编程问答-------------------- 改用contextmenu吧。 --------------------编程问答-------------------- 不显示，是不是高度限制了，所以显示不全，或者数据没绑定上。设置Listpicker的ZIndex --------------------编程问答-------------------- Listpicker 的弹出选择菜单如果没有改变控件的高度那List是不知道的。 --------------------编程问答-------------------- --------------------编程问答-------------------- 同问

是不是控件的样式或者层级错了导致的？
