实现ultrawingrid rows clear()功能

ultrawingrid 没有rows clear()功能

自己写了一个等同的功能代码

                while (shredBatchGrid.Rows.Count > 0)
                {
                    for (int i = 0; i <= shredBatchGrid.Rows.Count - 1; i++)
                    {
                        shredBatchGrid.ActiveRow = shredBatchGrid.Rows[i];
                        shredBatchGrid.Rows[i].Activate();
                        shredBatchGrid.Rows[i].Activated = true;
                        shredBatchGrid.Rows[i].Delete(false);
                    }
                }
