关于空值的问题

Question

偶做了一个关于dataGridView_CellValueChanged事件的代码，但里面有一个关于空值的处理始终不得其所……

 

private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
        {
            string connection = "server=192.100.3.3;database=AIS20090330165131;uid=sa;pwd=;";
            SqlConnection thisconection = new SqlConnection(connection);
            SqlCommand cmd = thisconection.CreateCommand();
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.CommandText = "t_StoreAndSale";
            cmd.CommandTimeout = 0;
            SqlParameter myParameter = new SqlParameter("@FFullNumber", SqlDbType.VarChar, 40);
            myParameter.Direction = System.Data.ParameterDirection.Input;
            myParameter.Value = dataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString().Trim();
            cmd.Parameters.Add(myParameter);
            SqlDataAdapter Adapter = new SqlDataAdapter();
            Adapter.SelectCommand = cmd;
            DataSet ds = new DataSet();
            Adapter.Fill(ds);    

            //问题所在：如果在SQL数据库里，“当日实入”到“AI结存”这10列都是空值，就是说在数据库里根本没有值，连Null值都不是,图片如下,当输入相应的物料代码，就会报“在位置0处没有任何行”，这样的问题如何解？请版主指点

       
            dataGridView1.Rows[e.RowIndex].Cells[1].Value = ds.Tables[0].Rows[0]["当日实入"];

            dataGridView1.Rows[e.RowIndex].Cells[2].Value = ds.Tables[0].Rows[0]["当月实入"];
            dataGridView1.Rows[e.RowIndex].Cells[3].Value = ds.Tables[0].Rows[0]["当日出货"];
            dataGridView1.Rows[e.RowIndex].Cells[4].Value = ds.Tables[0].Rows[0]["当月出货"];
            dataGridView1.Rows[e.RowIndex].Cells[5].Value = ds.Tables[0].Rows[0]["包装成品库存"];
            dataGridView1.Rows[e.RowIndex].Cells[6].Value = ds.Tables[0].Rows[0]["成品库存"];
            dataGridView1.Rows[e.RowIndex].Cells[7].Value = ds.Tables[0].Rows[0]["半成品库存"];
            dataGridView1.Rows[e.RowIndex].Cells[8].Value = ds.Tables[0].Rows[0]["包装投结存"];
            dataGridView1.Rows[e.RowIndex].Cells[9].Value = ds.Tables[0].Rows[0]["装配结存"];
            dataGridView1.Rows[e.RowIndex].Cells[10].Value = ds.Tables[0].Rows[0]["AI结存"];
        }
