DevExpress.XtraGrid.Views.BandedGrid.AdvBandedGridView 用法

一.以 DevExpress.XtraGrid.Views.BandedGrid.AdvBandedGridView advBandedGridView3 为实例 .根据不同条件实现AdvBandedGridView的扩展和收缩

 cbbExecuteState.SelectedIndexChanged += cbbExecuteState_SelectedIndexChanged;

  void cbbExecuteState_SelectedIndexChanged(object sender, EventArgs e)
        {
            if (cbbExecuteState.SelectedIndex == 3)
            {
                //扩展
                this.advBandedGridView3.GroupCount = 0;
                this.advBandedGridView3.SortInfo.RemoveAt(0);
                SelectRefreshTask();
            }
            else
            {
                //收缩
                this.advBandedGridView3.GroupCount = 1;
                this.advBandedGridView3.SortInfo.AddRange(new DevExpress.XtraGrid.Columns.GridColumnSortInfo[] {
            new DevExpress.XtraGrid.Columns.GridColumnSortInfo(this.bandedGridColumn5, DevExpress.Data.ColumnSortOrder.Ascending)});
                SelectRefreshTask();
            }
        }
