Introduced six new internal DTO classes: CatalogReadDto, CatalogWriteDto, DashboardInfoDto, LayoutDto, MassdataReadDto, and MassdataWriteDto. Each class resides in its appropriate namespace and currently contains no properties or methods, serving as placeholders for future data transfer logic.
Added new DbFirst.Contracts project targeting .NET 8.0 with nullable and implicit usings enabled. Included a project reference to DbFirst.Domain and updated the solution file to register the new project with all build configurations.
Upgraded AutoMapper to version 16.1.1 across API, Application, and Infrastructure projects. Removed AutoMapper.Extensions.Microsoft.DependencyInjection where no longer needed. Updated AutoMapper registration in DependencyInjection.cs to use the new API. No other changes made.
Replaced String.Empty and null! with string.Empty for string properties
in CatalogReadDto, CatalogWriteDto, and VwmyCatalog classes. This
ensures consistent initialization and helps prevent null reference
issues across the codebase.
Explicitly annotate DTO parameters with [FromBody] in CatalogsController (Create, Update) and MassDataController (Upsert) to ensure correct model binding from the request body and improve API clarity.
Replaces Array.Empty<string>() with the C# array literal [] when defaulting the CORS allowed origins array. This is a syntactic improvement with no change in behavior.
Changed default values of CatTitle, CatString, and AddedWho from null! to String.Empty to prevent potential null reference issues and ensure safer property initialization.
Refactored DashboardChangeNotifier and IDashboardChangeNotifier to use async notification with improved error handling and logging. Updated SqlDashboardStorage to call the new async notification method after dashboard changes, ensuring non-blocking and reliable client updates.
ExceptionHandlingMiddleware now returns structured ProblemDetails
responses for errors, including specific handling for
InvalidOperationException (400 Bad Request) and general exceptions
(500 Internal Server Error). Responses use "application/problem+json"
content type and include trace IDs. ProblemDetails support is also
registered in Program.cs.
Upgraded to MediatR 14.1.0 and updated registration to use the new syntax. Removed MediatR.Extensions.Microsoft.DependencyInjection where no longer needed. Bumped Microsoft.Extensions.DependencyInjection.Abstractions to 10.0.0 in Application and Infrastructure projects.
The GetAllAsync method, which returned all Massdata records, has been removed from the MassDataRepository class. No other changes were made in this commit.
Cleaned up unnecessary System.Net and System.Net.Http.Json usings across multiple files, including controllers and API client classes, to reduce dependencies and improve code clarity.
Move DashboardConfigurator setup from Program.cs to a new static DashboardConfiguratorFactory. This centralizes dashboard file creation, data source registration, and storage logic, improving code organization and maintainability. Unused usings are cleaned up accordingly.
Separated LayoutDto from LayoutsController.cs into LayoutDto.cs and set its namespace to DbFirst.Application.Layouts for better code organization and maintainability.
Validation preventing CatTitle changes during updates is now enforced in UpdateCatalogHandler instead of the controller. The handler throws an exception if a title change is attempted. Also, streamlined UpdateProcedure handling and removed redundant CatTitle mapping logic.
Centralize repository service registrations in Infrastructure's
DependencyInjection.cs for better maintainability and separation
of concerns. Remove direct registrations from Program.cs and
add necessary using statements.
Refactored code to use C# 12 collection expressions ([]) for initializing empty lists and dictionaries instead of the older constructors. This change modernizes and simplifies collection initialization across models, services, and API clients without altering any logic.
All API client interfaces and implementations now accept an optional CancellationToken parameter for each method. This enables consumers to cancel HTTP requests, improving responsiveness and resource management. No changes were made to core logic or return types; only method signatures and HttpClient calls were updated to support cancellation.
Introduce interfaces for all API clients and update dependency injection to use these interfaces. Refactor services and components to depend on abstractions instead of concrete implementations, improving testability and maintainability.
Replaced direct StateHasChanged() calls with InvokeAsync(StateHasChanged) to ensure asynchronous state updates. This helps prevent issues that can arise from synchronous state changes during component lifecycle events or event callbacks in Blazor.
Add a private _cachedLayoutUser field to BandLayoutService and update EnsureLayoutUserAsync to cache the layout user value after first retrieval or generation. This avoids repeated localStorage calls and improves performance.
Added @using DbFirst.BlazorWebApp and reorganized the placement of @using Microsoft.Extensions.Options to improve code organization and maintain consistent dependency order.
Replaced direct IConfiguration usage with a strongly-typed AppSettings class for accessing the API base URL. Registered AppSettings with DI and updated Dashboard.razor to use IOptions<AppSettings>. Updated using statements and DI setup for improved type safety and centralized configuration management.
Move shared state and methods from CatalogsGrid and MassDataGrid into BandGridBase<TItem>. This centralizes edit context handling, validation, popup header logic, row editing/deleting, and layout feedback, reducing duplication and improving maintainability. Individual grid components now only override OnEditFieldChanged for custom validation.
Simplified registration of CatalogApiClient, DashboardApiClient, MassDataApiClient, and LayoutApiClient by introducing a ConfigureClient method. This method sets the BaseAddress if ApiBaseUrl is configured, removing the previous if-else logic and reducing code duplication.
ApiResult<T> and its static methods were relocated from CatalogApiClient.cs to a new ApiResult.cs file. The new file now includes the DbFirst.BlazorWebApp.Models namespace for better code organization.
Replaced the private ReadErrorAsync method in LayoutApiClient with calls to ApiClientHelper.ReadErrorAsync, centralizing error handling logic for improved consistency and reuse.
Moved SignalR hub connection setup from OnInitializedAsync to OnAfterRenderAsync, ensuring initialization occurs only after the component's first render. This prevents premature connection attempts and aligns with best practices for component lifecycle management.
Introduce Add, Edit, and Delete buttons with Bootstrap Icons in the toolbars of CatalogsGrid and MassDataGrid. Hide the default command column by overriding ShowCommandColumn. Update BandGridBase to conditionally render the command column. Track focused row index for toolbar actions, enabling row operations via toolbar instead of the grid's built-in command column. Add Bootstrap Icons stylesheet to App.razor.
- Set default width and hide new button for DxGridBandColumn in BandGridBase.cs
- Always show column chooser button in CatalogsGrid and MassDataGrid
- Add "Spalten" toolbar button to open column chooser dialog
- Improves accessibility and consistency of grid column customization
Replaced custom Fluent theme registration (with ApplyToPageElements set to true) with the default Fluent theme registration, removing unnecessary property customization for a cleaner setup.
Previously, RefreshDashboards() was called automatically if the dashboards list was empty during parameter setting. This logic has been removed, so dashboards will no longer refresh automatically in this scenario.
Refactored error handling logic for API responses into a new static ApiClientHelper class, consolidating the ReadErrorAsync method and ProblemDetailsDto. Updated CatalogApiClient and MassDataApiClient to use the shared helper, removing redundant local methods and classes. This change improves consistency, reduces duplication, and streamlines error message formatting across the application.
MassDataApiClient.UpsertAsync now returns ApiResult to standardize success and error reporting, including detailed error extraction from API responses. Updated MassDataGrid.razor to handle the new result type and display error messages accordingly. Removed obsolete try-catch logic in favor of the new pattern.
The protected bool bandEditorExpanded, which tracked the expansion
state of the band editor, has been removed from BandGridBase<TItem>
as it is no longer used. This helps clean up unused state from
the component.
Extract band editor UI and logic from CatalogsGrid.razor and MassDataGrid.razor into a new BandEditor.razor component. This centralizes band management features (add/remove bands, edit captions, assign columns, save/reset layout) and reduces code duplication, improving maintainability and reusability. Existing UI and event handling remain functionally unchanged.
Move band and column management to BandGridBase, reducing duplication in MassDataGrid. Column definitions and layout key are now provided via overridden properties. Band editor actions now use feedback methods for user messages. Grid layout application and error display are streamlined. Improves maintainability and enables reuse across grid components.
Refactored CatalogsGrid.razor to inherit from BandGridBase<CatalogReadDto>, moving band layout and grid logic into the base class. Updated UI to use new async methods for saving and resetting the layout with user feedback. Removed redundant local fields and methods, centralizing layout management and improving maintainability and code reuse. Error and info messages are now shown after layout operations.
Introduced an abstract base class BandGridBase<TItem> to centralize banded grid functionality in Blazor apps using DevExpress. This class manages band layouts, column definitions, user-specific layout persistence, grid size modes, and rendering logic. It integrates with BandLayoutService for layout storage and retrieval, and is intended for inheritance by specific grid components.
Comprehensive documentation for the DbFirst solution, detailing project goals, architecture (Clean Architecture), technology stack, solution/project structure, Database-First approach, CQRS with MediatR, API endpoints, Blazor/DevExpress frontend, dashboard and layout persistence, SignalR integration, configuration, development setup, architecture decisions (ADRs), extensibility, and glossary. Includes diagrams, code snippets, and workflow guidance for the developer team.
Introduced --grid-stripe-bg CSS variable for both light and dark themes to enable zebra-striping in dxbl-grid components. Applied background color to even-numbered grid rows for improved readability.
