1.GridView无代码分页排序：
1.AllowSorting设为True，aspx代码中是AllowSorting="True"；
2.默认1页10条，如果要修改每页条数，修改PageSize即可，在aspx代码中是PageSize="12"。3.默认的是单向排序的，右击GridView弹出“属性”，选择AllowSorting为True即可。2.GridView选中，编辑，取消，删除：
后台代码：你可以使用sqlhelper,本文没用。代码如下：

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e) { string sqlstr = "delete from 表 where id=‘" + GridView1.DataKeys[e.RowIndex].Value.ToString() + "‘"; sqlcon = new SqlConnection(strCon); sqlcom = new SqlCommand(sqlstr,sqlcon); sqlcon.Open(); sqlcom.ExecuteNonQuery(); sqlcon.Close(); bind(); }//更新
