  有一系统使用的是VS2008 .NET 2下的DevExpress 8.1,现需要升级到VS2010 .NET 4下的DevExpress 18.1,因为DevExpress版本的变化,代码需要做兼容性处理,目前发现的问题和解决办法如下:

  一、版本转换

  1.1、项目升级到.NET 4由VS2010完成

  1.2、DevExpress版本升级由DevExpress Project Converter完成

 

  二、编译错误

  2.1、DevExpress.Data.Filtering.GroupOperator的Operands,类型由ArrayList改为DevExpress.Data.Filtering.CriteriaOperatorCollection

  

  2.2、DevExpress.XtraGrid.Views.Base.CustomColumnDisplayTextEventArgs的RowHandle已移除,改为使用ListSourceRowIndex处理(详见https://www.devexpress.com/Support/Center/Question/Details/T108839/why-the-customcolumndisplaytexteventargs-rowhandle-property-no-longer-exists-in-gridview

  

  2.3、DevExpress.XtraCharts.XYDiagram的BackColor,改为DefaultPane.BackColor(详见https://www.devexpress.com/Support/Center/Question/Details/Q35555/change-background-color-of-xydiagram-pane-graph

  

  2.4、DevExpress.XtraCharts.PercentOptions的ValuePercentPrecision,改名为PercentageAccuracy(详见https://www.devexpress.com/Support/Center/Question/Details/AS10911/pointoptions-rename-the-valuepercentprecision-property-to-percentageaccuracy-and-set-the

  

  2.5、DevExpress.XtraPivotGrid.PivotGridHitInfo不再包含FieldCellViewInfo,原FieldCellViewInfo的Field用DevExpress.XtraPivotGrid.PivotGridHitInfo的Field代替(详见https://www.devexpress.com/Support/Center/Question/Details/Q159088/how-to-determine-whether-the-current-field-value-is-a-column-field-value

  

  2.6、DevExpress.XtraScheduler的Appointment已经变更为接口,其实例可通过DevExpress.XtraScheduler.Compatibility.StaticAppointmentFactory.CreateAppointment或DevExpress.XtraScheduler.SchedulerDataStorage.CreateAppointment构建(详见https://www.devexpress.com/Support/Center/Question/Details/T306810/how-to-resolve-issues-related-to-changes-in-schedulercontrol-s-public-api-after

  

 

  三、布局问题

  3.1、窗体变大,控件变大且位置发生变化。该问题在双字符集操作系统下由于XtraForm的Bug引起。

  解决办法:删除Designer文件中XtraForm的AutoScaleDimensions和AutoScaleMode赋值(详见https://www.devexpress.com/Support/Center/Question/Details/B133111/controls-width-changed-when-update-from-v8-2-to-v8-3

  

  

  3.2、LayoutControl内控件与边框距离变大。

  解决办法:设置LayoutControl的OptionsView.UseSkinIndents为false(详见https://www.devexpress.com/Support/Center/Question/Details/B139369/every-layoutcontrolgroup-has-unexpected-padding-value-after-update-to-9-2-4

  

  

  3.3、皮肤效果丢失。

  解决办法:添加引用库DevExpress.BonusSkins,在所有控件创建之前,执行一次DevExpress.UserSkins.BonusSkins.Register()(详见https://www.devexpress.com/Support/Center/Question/Details/T666943/waitform-how-to-use-the-caramel-skin

  

  

 

  最后附上Dexpress .NET各版本和.NET Framework的对应关系表
