EasyUi 动态列

最近，接到一个需求，按部门做了个数据统计，原以为是个很普通的需求，具体实现的过程中，却发现，这个部门是不固定的，因为部门有可能被增、删、改。

所以，对应的列也是不固定的，这下可难倒我了。

不过，在我锲而不舍，刻苦钻研，外加百度、360搜索的帮助下，总算有了点思路。

具体的思路是这样子的：

1，将JS定义的Columns放在后台定义，在后台时融合部门列表，再返回到前端。

2，在后台对第一列的部门赋值，并返回Json。

有了思路，实现起来就不难了。

具体做法：1，JS获取列定义

        function GetData() {
            $.post("/DataManage/GetReportColumn", {}, function (txt) {
                if (txt != "") {
                    var columnsSetting = eval(txt);

                    initParam.url = '/DataManage/GetInputReportByDeptList';
                    initParam.queryParams = {IsEntire: "N"};
                    initParam.columns = columnsSetting;
                    //initParam.toolbar = builderAddEditDelToolbar('部门管理', "/DeptManage");
                    builderDatagrid(initParam);
                }
            })
        }

2,再根据列定义方法，去实现DataGrid

3,方法GetReportColumn的相关代码如下：

        public ActionResult GetReportColumn()
        {
            IList<DepartmentModel> deptList = GetDeptList();

            List<EasyUiColumnModel> columns = new List<EasyUiColumnModel>();
            columns.Add(new EasyUiColumnModel { field = "BatchNo", title = "批次号", width = 250, sortable = true });
            for (int i = 1; i < deptList.Count + 1; i++)
            {
                columns.Add(new EasyUiColumnModel { field = "Dept" + i, title = deptList[i - 1].Name, width = 100 });
            }

            var cols = JsonExtension.JsonSerializer(columns);
            return Content(cols);
        }

4，方法GetInputReportByDeptList的相关代码如下：

        /// <summary>
        /// 统计报表Json
        /// </summary>
        /// <returns></returns>
        public ActionResult GetInputReportByDeptList()
        {
            String isEntire = RequestExtension.GetForm<String>("IsEntire", "");

            String batchNo = RequestExtension.GetForm<String>("BatchNo", "");
            int currentPageIndex = RequestExtension.GetForm<int>("page", 0);
            int pagesize = RequestExtension.GetForm<int>("rows", 0);
            String sort = RequestExtension.GetForm<String>("sort", "");
            String order = RequestExtension.GetForm<String>("order", "");

            string json = RequestExtension.GetFormData();
            json = HttpUtility.UrlDecode(json);
            BatchInfoModel viewModel = JsonExtension.JsDeserialize<BatchInfoModel>(json);

            Pagination pagin = new Pagination
            {
                CurrentPageIndex = currentPageIndex,
                PageSize = pagesize,
                OrderBy = String.IsNullOrEmpty(sort) ? "" : String.Concat(sort + " " + order)
            };

            BatchInfoModel batchInfoCondition = new BatchInfoModel();
            batchInfoCondition.IsEntire = isEntire;
            if (viewModel != null)
            {
                batchInfoCondition.SourceNo = viewModel.SourceNo;
                batchInfoCondition.StartDate = viewModel.StartDate;
                batchInfoCondition.EndDate = viewModel.EndDate;
                batchInfoCondition.IsEntire = viewModel.IsEntire;
                batchInfoCondition.BatchNo = viewModel.BatchNo;
            }
            KeyValuePair<Pagination, IList<BatchInfoModel>> batchInfoList = batchInfoRepository.BatchInfoPagination(pagin, batchInfoCondition);

            IList<DepartmentModel> deptList = GetDeptList();

            foreach (var item in batchInfoList.Value)
            {
                for (int i = 0; i < deptList.Count; i++)
                {
                    //判断该部门的成员是否有导入Citas
                    var downInfo = downLoadInfoRepository.GetDownLoadInfoByBatchIDAndDeptID(item.BatchNo, deptList[i].ID);
                    if (downInfo != null)
                    {
                        String importTime = "-" + downInfo.CreateTime.ToString("yyMMdd");

                        if (i == 0) item.Dept1 = "Y" + importTime;
                        if (i == 1) item.Dept2 = "Y" + importTime;
                        if (i == 2) item.Dept3 = "Y" + importTime;
                        if (i == 3) item.Dept4 = "Y" + importTime;
                        if (i == 4) item.Dept5 = "Y" + importTime;
                        if (i == 5) item.Dept6 = "Y" + importTime;
                        if (i == 6) item.Dept7 = "Y" + importTime;
                        if (i == 7) item.Dept8 = "Y" + importTime;
                        if (i == 8) item.Dept9 = "Y" + importTime;
                        if (i == 9) item.Dept10 = "Y" + importTime;
                        if (i == 10) item.Dept11 = "Y" + importTime;
                        if (i == 11) item.Dept12 = "Y" + importTime;
                        if (i == 12) item.Dept13 = "Y" + importTime;
                        if (i == 13) item.Dept14 = "Y" + importTime;
                        if (i == 14) item.Dept15 = "Y" + importTime;
                        if (i == 15) item.Dept16 = "Y" + importTime;
                        if (i == 16) item.Dept17 = "Y" + importTime;
                        if (i == 17) item.Dept18 = "Y" + importTime;
                        if (i == 18) item.Dept19 = "Y" + importTime;
                        if (i == 19) item.Dept20 = "Y" + importTime;
                        if (i == 20) item.Dept21 = "Y" + importTime;
                        if (i == 21) item.Dept22 = "Y" + importTime;
                        if (i == 22) item.Dept23 = "Y" + importTime;
                        if (i == 23) item.Dept24 = "Y" + importTime;
                        if (i == 24) item.Dept25 = "Y" + importTime;
                        if (i == 25) item.Dept26 = "Y" + importTime;
                        if (i == 26) item.Dept27 = "Y" + importTime;
                        if (i == 27) item.Dept28 = "Y" + importTime;
                        if (i == 28) item.Dept29 = "Y" + importTime;
                        if (i == 29) item.Dept30 = "Y" + importTime;
                    }
                }
            }
            return JsonExtension.JsonPagination(batchInfoList.Value, pagin.CurrentPageIndex, pagin.PageSize, batchInfoList.Key.TotalItemCount);
        }

So,实现的效果如下，这样随便他增、删、改部门（目前只支持30个部门以下），我的统计报表不会错。
