# 【场景】
针对部分字段，列表不支持字段排序（如仓位），同时不支持列表多选（无法修改返回顺序）；
在条码打印中需要按照数据仓位排序打印时无法实现。
# 【案例】
即时库存、条码打印，按照仓位组合值排序
# 【方案】
在条码打印界面（BD_BarCodePrint），配置表单插件,增加一个排序的单据体菜单；对单据体数据包进行排序，排序后打印则按照仓位顺序输出。
```csharp
using Kingdee.BOS.Core.Bill.PlugIn;
using Kingdee.BOS.Core.DynamicForm.PlugIn;
using Kingdee.BOS.Core.DynamicForm.PlugIn.Args;
using Kingdee.BOS.Core.Metadata.EntityElement;
using Kingdee.BOS.Core.Metadata.FieldElement;
using Kingdee.BOS.Orm.DataEntity;
using Kingdee.BOS.Util;
namespace DynamicFormPlugIn.BarCodePrint
{
public class BarcodePlugIn : AbstractBillPlugIn
{
public override void EntryBarItemClick(BarItemClickEventArgs e)
{
base.EntryBarItemClick(e);
if (e.BarItemKey.EqualsIgnoreCase("CustomSort"))
{
SortEntity();
}
}
private void SortEntity()
{
const string EntityKey = "FEntityToBill";
const string SortField = "FSTOCKLOCID";
EntryEntity entity = View.BillBusinessInfo.GetEntity(EntityKey) as EntryEntity;
if (entity == null)
return;
RelatedFlexGroupField flexField = View.BillBusinessInfo.GetField(SortField) as RelatedFlexGroupField;
if (flexField == null)
return;
BaseDataField bdField = View.BillBusinessInfo.GetField(flexField.RelatedBaseDataFlexGroupField) as BaseDataField;
if (bdField == null)
return;
DynamicObjectCollection rowObjs = View.Model.GetEntityDataObject(entity) as DynamicObjectCollection;
rowObjs.Sort(rowObj =>
{
var flexObj = rowObj[flexField.PropertyName] as DynamicObject;
if (flexObj == null)
return string.Empty;
var bdObj = rowObj[bdField.PropertyName] as DynamicObject;
if (bdObj == null)
return string.Empty;
return ObjectUtils.Object2String(flexField.GetDisplayName(this.View, flexObj, bdField, bdObj));
});
const string Seq = "Seq";
int seqVal = 1;
foreach(var rowObj in rowObjs)
{
rowObj[Seq] = seqVal++;
}
View.UpdateView(EntityKey);
}
}
}
```
# 【演示效果】
<1>选单后，点击排序，列表数据按照仓位排序；点生成条码，最终按照数据顺序生成。
<2>不点排序，直接生成，还是按照原来的数据顺序生成。
