ASP.NET WebForm 回传机制
为什么每个WebForm.aspx都必须包含在form之中
<form runat="server">
//html
</form>在asp.net WebForm中，点击一个提交按钮提交数据采用的post方式， 这种方式会将<form></form>中所有包含name属性的元素提交到服务器，像下面这样

如果是使用UpdatePanel ，也是将整个页面进行提交，只是服务器仅返回UpdatePanel所包含的数据，因为UPdatePanel也是使用Post方式进行提交，而asp.net WebForm页面只能包含一个<form></form>所以只能提交这个唯一form，而且如果UPdatePanel采用get方式，如果数据过多，超过get所限制的范围，所以不能使用get方式。
