Gridview绑定数据后怎实现数据的查询功可以？

string cmdText="select * from 表 where 字段==所查询数据"
SqlConnection con = new SqlConnection(ConnString);

SqlDataAdapter sda = new SqlDataAdapter(cmdText, con);
DataSet dt = new DataSet();
sda.Fill(dt);
this.GridView1.DataSource = dt.table[0];//dt.DefaultView();
this.GridView1.DataBind();
你试试，我一般是这样写绑定的。
