- 2 minutes to read
This topic describes how to enable UI elements you can use to manage Model Differences stored in the database.
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 WinForms, ASP.NET WebForms, or ASP.NET Core Blazor application:
Open the Module.cs file and add the following code to the Module constructor:
using DevExpress.Persistent.BaseImpl; // ... namespace MainDemo.Module { public sealed partial class MainDemoModule : ModuleBase { public MainDemoModule() { // ... AdditionalExportedTypes.Add(typeof(ModelDifference)); AdditionalExportedTypes.Add(typeof(ModelDifferenceAspect)); } // ... } }
If you use the Entity Framework Core, ensure that your DbContext contains the following lines:
using DevExpress.Persistent.BaseImpl.EF; // ... public class MyDbContext : DbContext { // ... public DbSet<ModelDifference> ModelDifferences { get; set; } public DbSet<ModelDifferenceAspect> ModelDifferenceAspects { get; set; } }
Run the Model Editor and create a new Navigation Item for the ModelDifference_ListView List View.
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.
