This topic describes how to enable UI elements you can use to manage Model Differences stored in the database.
本主题介绍如何启用可用于管理数据库中存储的模型差异的 UI 元素。
Note 注意
Mobile applications do not support Users' Model Differences.
移动应用程序不支持用户的模型差异。
The Administrative UI allows application administrators to manage user settings in user accounts - create, copy, export and reset Model Differences. Follow the steps below to enable this UI in your application:
管理 UI 允许应用程序管理员管理用户帐户中的用户设置 - 创建、复制、导出和重置模型差异。按照以下步骤在应用程序中启用此 UI：
1.If you use XPO, run the Module Designer and add the ModelDifference and ModelDifferenceAspect types to the module in the Exported Types section:
如果使用 XPO，则运行模块设计器，并将"模型差异"和"模型差异"方面类型添加到"导出类型"部分中的模块：
If you use the Entity Framework, register the ModelDifference and ModelDifferenceAspect entity types within your DbContext:
如果使用实体框架，请在 DbContext 中注册模型差异和模型差异方面实体类型：
using DevExpress.Persistent.BaseImpl.EF; // ... public class MyDbContext : DbContext { // ... public DbSet<ModelDifference> ModelDifferences { get; set; } public DbSet<ModelDifferenceAspect> ModelDifferenceAspects { get; set; } }
2.Run the Model Editor and create a new Navigation Item for the ModelDifference_ListView List View.
运行模型编辑器，并为ModelDifference_ListView列表视图创建新的导航项。
Run the application and click this Navigation Item to open the Model Difference List View. Ensure that the Model Differences management Actions are available in the Tools category.
运行该应用程序并单击此导航项以打开模型差异列表视图。确保"工具"类别中的"模型差异管理操作"可用。
Users who used the application at least once have initialized Model Differences. The List View lists these Model Differences. This View also contains the Shared Model Difference record that stores global settings. Click Create Model Differences to create Model Differences for unlisted users. Click Import Shared Model Difference to load shared Model Differences created in Visual Studio (the Model.xafml file). You can also copy, export and reset a selected record. Refer to the Model Difference Storages article's Administrative UI section for more information about these Actions.
至少使用过一次应用程序的用户已初始化模型差异。列表视图列出了这些模型差异。此视图还包含存储全局设置的共享模型差异记录。单击"创建模型差异"为未列出的用户创建模型差异。单击"导入共享模型差异"以加载在 Visual Studio 中创建的共享模型差异（Model.xafml 文件）。您还可以复制、导出和重置选定的记录。有关这些操作的详细信息，请参阅模型差异存储一文的"管理 UI"部分。
Note 注意
The Export Model Differences Action saves model differences to the application's ExportedModelDifferences subfolder. Use the ModelDifferenceViewController.ExportedModelDifferencesPath property to change the folder.
Restart an ASP.NET application on the web server to apply changes if you changed its global settings (for example, using the Import Shared Model Difference Action).
导出模型差异操作将模型差异保存到应用程序的"导出模型差异"子文件夹。使用模型差异视图控制器.导出模型差异路径属性来更改文件夹。
在 Web 服务器上重新启动ASP.NET应用程序以应用更改（例如，使用"导入共享模型差异操作"）。更改其全局设置。
