回传表单隐藏DIV

Question

I have a contest form that is a usercontrol, it sits on page that has several usercontrols on it. When a user clicks a button it displays this form which resides in usercontrol, the div (which is on the page) is hidden at first. The only problem I am running into is when the page post backs it hides the DIV even when there is an error. I need it to keep the DIV open if there is an error, the code logic for form validation is in the usercontrol so how could I access the DIV that is on the page? The page is a masterpage, we dont do any code logic in our masterpages, is there anyway to accomplish this without code on the masterpage?

最好的方法是公开一些属性，该属性指示用户控件上是否发生任何错误，然后根据该用户控件属性在页面本身上设置Div的可见性。
