C# 两个DataGridView数据移动问题

Question

C# 两个DataGridView数据移动问题需求： 
 1、选择上部DataGridView药品信息后，点击分配按钮，上部DataGridView所选药品信息去除，增加到下部DataGridView中（分配按钮）
 2、选择下部DataGridView药品信息后，点击撤消分配按钮，下部DataGridView所选药品信息去除，增加到上部DataGridView中（撤消分配按钮） 

Answer 1

在上下两个DataGridView所绑定的数据源中操作，根据选中的数据的ID，在数据绑定数据源中做增加删除数据行操作，然后重新绑定数据。

Answer 2

如果用Datatable作数据源的话就比较简单了，直接修改两个table中的数据，重新绑定就可以了

Answer 3

解决办法源代码如下：
         ArrayList AL = new ArrayList();
        ArrayList ALDetail = new ArrayList();
 #region 明细表datagridview 事件
        private void dgvDocSaleD_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            try
            {
                if (this.dgvDocSaleD.Rows.Count > 0)
                {                    if (e.ColumnIndex == 0 && e.RowIndex != -1)
                    {
                        if (this.dgvDocSaleD.Rows[e.RowIndex].Cells[0].EditedFormattedValue.ToString() == "True")
                        {
                            ALDetail.Add(dgvDocSaleD.SelectedRows[0].Cells["MedID"].Value.ToString());
                        }
                        else
                        {
                            return;
                        }                    }
                }
            }
            catch (Exception ex)

                    //将所选药品添加到下部临时表中
