分组常用代码如下:

//设置 group 信息FarPoint.Web.Spread.SheetView sv = this.FpSpread1.ActiveSheetView;//设置表头双击是否可以分组//sv.AllowGroup = true;gdm = new GroupDataModel(sv.DataModel);Session["dataModel"] = gdm;sv.DataModel = gdm;FarPoint.Web.Spread.SortInfo[] sort = new FarPoint.Web.Spread.SortInfo[1];//设置分组列和排序方式(默认以第1列分组,列数从0开始计数)sort[0] = new FarPoint.Web.Spread.SortInfo(1, true);gdm.Group(sort);//隐藏分组底部(常用于合计之类)//FarPoint.Web.Spread.Model.Group group = new Group(gdm, (FarPoint.Web.Spread.Model.Group)gdm.Groups[0], 0, false);//GroupFooter groupfooter = new GroupFooter(group);//FpSpread1.Sheets[0].GroupFooterVisible = true;////设置 ColumnFooter,GroupFooter 第1列公式为 Sum ,用于计算第5列所有单元格加和.//this.FpSpread1.ActiveSheetView.Columns[0].AggregationType = FarPoint.Web.Spread.Model.AggregationType.Sum;
