[wohuihenkuaile]

 //修改仓库
        private void EditWareHouse_Click(object sender, EventArgs e)
        {
            try
            {
                MessageBox.Show(gridView1.FocusedRowHandle.ToString()); //获取到的焦点总为负数
            }
            catch (Exception ex) 
            {
                MessageBox.Show(ex.Message);
            }
        }
