1.The model backing the 'XXXXDBContext' context has changed since the database was created. Either manually delete/update the database, or call Database.SetInitializer with an IDatabaseInitializer instance. For example, the DropCreateDatabaseIfModelChanges strategy will automatically delete and recreate the database, and optionally seed it with new data.
出現上述錯誤需要在Global.asax中的Application_Start方法中加入：
Database.SetInitializer<Models.XXXXDBContext>(null);
2.<a>標籤在display：block設置下不能居中的問題。
把display:block改爲display:inline-block就OK了。
3.如果用<a>標籤代替submit按鈕。
<a href="javascript:;" οnclick="javascript:document.forms[0].submit();">保存</a>
