表格上添加变乱触发ItemsSourceChanged属性，触发变乱
<c1:C1FlexGrid Name="CfgSaleOrderReviewItem" Style="{StaticResource Green}" ItemsSource="{Binding SaleOrderList,Mode=TwoWay}" SelectedItem="{Binding CurrentSaleOrderItem,Mode=TwoWay}" 
                        LoadedRows="FlexGrid_LoadedSaleOrderRows_RowIndex" PreviewKeyDown="c1FlexGrid_PreviewKeyDown"  IsReadOnly="False"

            if (vm.SaleOrderList != null && vm.SaleOrderList.Count > 0) {
                CfgSaleOrderReviewItem.ColumnFooters.Rows.Add(gr);
                gr["ManagerName"] = "合计";
                gr["roductQuantity"] = vm.SaleOrderList == null ? 0 : vm.SaleOrderList.Sum(p => Convert.ToInt32(p.ProductQuantity));
                gr["roductTotalArea"] = vm.SaleOrderList == null ? 0 : vm.SaleOrderList.Sum(p => Convert.ToDouble(p.ProductTotalArea));
