Create an ObjectDataSource+TableAdapter to expose CRUD methods，and bind to the GridView by enabling its CRUD functions。
【Reasons】
If you create a new instance of TableAdapter from time to time，I think it cannot "remember" what it used to have，So there will be confliction when rendering the page……。So you need a "consistance" TableAdapter，with a table inside。So ObjectDataSource is better。
