在detailsview使用dropdownlist更新不成功

Question

各路高手，小弟是个ASP.NET菜鸟，最近在做关于毕业设计的一些板块，问题一直解决不了 ，希望各位可以帮一下忙我是直接拖dropdownlist放在detailsview里面，凡是使用dropdownlist的部分都更新不成功，性别使用dropdownlist中的项，value是1或0.更新时没变化，学历、学位、职称、级别、荣誉几处也是使用dropdownlist，更新时一直为空，我已经把它们绑定了数据源，显示的数据字段是名字，值的数据字段是ID，我猜可能是取不了value值，但具体我不是很清楚，之前有试过直接给selectvalue绑定各个数据源ID的字段，但是更新时候说“不包含名为"XXX的属性"”，更新数据库用的是存储过程，测试过应该是没问题的
各路大侠，帮帮忙，毕业设计很重要呀，小弟先谢谢各位！！
