十万火急，求助

上代码，图啥都看不出来，数据就是没出来，但是查询出来了没有

查询
            SqlConnection con = new SqlConnection(ConnStr);
            string str = "select * from tb_user";
            adp = new SqlDataAdapter(str, con);
            DataSet ds = new DataSet();
            adp.Fill(ds, "tb_user");
            SqlCommandBuilder MyCb = new SqlCommandBuilder(adp);
            MyTab = ds.Tables["tb_user"];
            MyTab.PrimaryKey = new DataColumn[] { MyTab.Columns["uacc"] };
            DataGridView.MultiSelect = false;
            if (this.checktxt.Text != string.Empty)
            {
                bindingSource1.DataSource = MyTab;
                bindingNavigator1.BindingSource = bindingSource1;
                DataGridView.DataSource = bindingSource1;
                DataView dv = ds.Tables["tb_user"].DefaultView;
                dv.RowFilter = "uacc like '%" + checktxt.Text.Trim() + "%'";
            }

删除、更新、修改、添加 都先用sql语句 然后再通过C#中语
            conn.Open();
            SqlCommand myCmd = new SqlCommand(sqlStr ,conn);            
             = CommandType.Text;  
            myCmd.ExecuteNonQuery();//执行sql语句
            conn.Close();
来执行sql语句 就可以实现
