ZC公司员工评分系统——前台排版算法

 

    教务系统的评教系统告一段落后，又开始做ZC公司的员工评分系统，总体用时6天，下面总结一下这忙碌的6天中用到得技术上的东西。

前台具体评分界面排版，需要的算法，关键是注意边界行的效果实现。

       GridView界面：

    

	GroupCol(gvDetail, 0);//合并第一列
        //GroupCol(gvDetail, 2);//合并第三列
        #region //从第几行到第几行合并
        int bCol = 0;
        string rowText = gvDetail.Rows[0].Cells[0].Text.ToString();

        for (int i = 0; i < gvDetail.Rows.Count + 1; i++)
        {
            if (i == gvDetail.Rows.Count)//注意边界行，因为它的规律和其他行不一样，所以单拿出来
            {
                GroupCol(gvDetail, 3, bCol, i);
                GroupCol(gvDetail, 2, bCol, i);
                return;
            }
            if (gvDetail.Rows[i].Cells[0].Text != rowText)
            {
                rowText = gvDetail.Rows[i].Cells[0].Text;
                GroupCol(gvDetail, 3, bCol, i);//从第几行到第几行合并
                GroupCol(gvDetail, 2, bCol, i);
                bCol = i;
            }
        }
        #endregion

        #region test 简单有限数据实验
        //GroupCol(gvDetail, 4, 0, 2);
        //GroupCol(gvDetail, 4, 2, 4);
        //GroupCol(gvDetail, 4, 4, 6);
        #endregion
    }
