DevExpress.XtraGrid.Columns.GridColumn column = gridViewList.Columns["No"];
if (column == null)
{
return;
}
column.SortMode = DevExpress.XtraGrid.ColumnSortMode.Value;
column.GroupIndex = 0;
DevExpress.XtraGrid.GridGroupSummaryItem item = new DevExpress.XtraGrid.GridGroupSummaryItem();
//根据第一个分组的条件计算总计数
if (i == 0)
{
item.DisplayFormat = "(总计：{0})";
item.SummaryType = DevExpress.Data.SummaryItemType.Count;
}
//展开分组的节点
gridViewList.OptionsBehavior.AutoExpandAllGroups = true;
gridViewList.GroupSummary.Add(item);
代码问题在于这里的GroupIndex永远都为-1 想知道怎么解决
排序的代码：
GridColumn columnNo = this.gridViewList.Columns.ColumnByFieldName(filedName);
this.gridViewList.SortInfo.Add(new GridColumnSortInfo(columnNo, DevExpress.Data.ColumnSortOrder.Descending));
不清楚为什么排序无效果。
