根据条件改变采购订单明细字段的颜色

通过python注册表单插件实现单据体颜色控制，以采购订单为例 ```python import clr clr.AddReference('mscorlib') from System import * def AfterBindData(e): SetBackColor() def DataChanged(e): if e.Field.Key == "FPRICE": SetBackColor() def SetBackColor(): entity = this.View.BusinessInfo.GetEntity("FPOOrderEntry") entrys = this.View.Model.GetEntityDataObject(entity) grid = this.View.GetControl(entity.Key) for entry in entrys: rowIndex = this.View.Model.GetRowIndex(entity, entry) if entry["PRICE"] < 10
