方法一：纯代码

this.list.gridControl.ItemsSource = lsItem;                this.list.gridControl.GroupBy("GroupTitle");                this.list.gridControl.Columns["GroupTitle"].SortOrder = ColumnSortOrder.Descending;                //this.list.gridControl.SortBy(this.list.gridControl.Columns["GroupTitle"], ColumnSortOrder.Descending);                this.list.gridControl.ExpandAllGroups();

 

方法二：XAML定义，构造函数中绑定

 

 

实时分组（先取消之前的分组）

private void ListGrouping(string strType)        {            if (string.IsNullOrEmpty(strType)) return;            if (strType == "Room")            {                //ColumnView.SortInfo                this.list.gridControl.SortInfo.Clear();//clear grouping                this.list.gridControl.GroupBy("RoomName");                this.list.gridControl.Columns["RoomName"].SortOrder = ColumnSortOrder.Ascending;                this.list.gridControl.ExpandAllGroups();             }            else if (strType == "Status")            {                this.list.gridControl.SortInfo.Clear();//Clear grouping                this.list.gridControl.GroupBy("Status");                this.list.gridControl.Columns["Status"].SortOrder = ColumnSortOrder.Ascending;                this.list.gridControl.ExpandAllGroups();            }         }
