Moved InitializeBandLayoutAsync() from OnInitializedAsync() to OnAfterRenderAsync() in CatalogsGrid.razor and MassDataGrid.razor. Now initialization occurs only on first render, followed by StateHasChanged(), to ensure proper layout setup after initial rendering. This addresses potential timing or rendering issues.
Replaced direct configuration access for the API base URL with retrieval from an AppSettings object. Updated HttpClient configuration to use appSettings.ApiBaseUrl, improving consistency and maintainability. Existing AppSettings DI registration is retained.
Explicitly catch JsonException and NotSupportedException when reading problem details from HTTP responses. Add comments to clarify that these errors are ignored since problem details are optional, making error handling more precise and avoiding unintended exception swallowing.
Refactored several methods in BandGridBase<TItem> to async Task and updated their invocations to use await. EventCallbacks for date filter changes now use async lambdas. Awaited InvokeAsync(StateHasChanged) to ensure UI updates after async operations. These changes improve UI state consistency and reliability in Blazor.
Refactored OnThemeChanged in MainLayout.razor to use InvokeAsync for proper synchronization of UI updates and async logic, preventing threading issues. Also added a blank line after app.Run() in Program.cs (no functional impact).
Added logic to synchronize the date filter UI with the current
filter criteria by updating _filterFrom and _filterTo based on
the CriteriaOperator. Introduced SyncDateFilterFromContext and
ParseDateOperand helpers to extract and apply "from" and "to"
date values, ensuring UI and filter state remain consistent.
Add _filterContexts to track filter menu contexts per field and update their FilterCriteria when criteria change, ensuring the date filter UI stays in sync. Remove CSS that hid the native Apply/Clear footer in the date filter dropdown.
Introduced a custom date range filter menu for date columns in BandGridBase<TItem> using DevExpress Blazor grids. The new UI provides "from" and "to" date pickers, applies filters immediately on selection, and hides the default filter dropdown footer for a smoother user experience. State management and filter criteria logic were added to support this feature.
Added custom colors for .dxbl-btn-dropdown-popup in dark mode to improve dropdown item visibility. Also added Bootstrap me-2 class to the "Spalten" toolbar button for better spacing.
Implements a dark mode override system for DevExpress Blazor themes lacking native dark support. Adds a JS function to toggle a dx-dark class on <html>, updates ThemeState to detect native dark themes, and applies targeted CSS variable overrides for consistent dark styling. Disables prerendering to ensure JS interop, and improves theme switching logic and documentation.
Refactor NavMenu to use DevExpress DxTreeView for navigation, replacing the old NavLink-based menu. Update sidebar and navigation row styling to use CSS variables, remove Bootstrap-specific and SVG icon CSS, and add a responsive hamburger menu for small screens. Improve dark mode support and overall maintainability.
Wrapped the Dark Mode toggle button in a span with left margin
for better separation from the theme combo box. Added a new
.btn-gap CSS class to standardize button spacing in the top row.
Introduce a DxComboBox in MainLayout for selecting between multiple themes. Update ThemeState to manage the current theme, provide a list of available themes, and apply the selected theme via a new SetTheme method. Refactor dark mode handling to work with the new theme system, and ensure UI updates on theme or mode changes.
Clean up and reorganize using/import statements across the solution. Remove unnecessary DTO imports from Application and Infrastructure layers, and ensure Contracts DTOs are only referenced in API and BlazorWebApp layers. No business logic is changed; these updates improve code organization, reduce coupling, and clarify architectural separation between layers.
Reorganize and deduplicate using directives in _Imports.razor for clarity and maintainability. Explicitly cast UpdateProcedure to CatalogUpdateProcedure in CatalogsGrid.razor to enforce type safety. Restore necessary DevExpress and DbFirst namespaces.
Refactored DTO class and namespace names from Massdata* to MassData* in DbFirst.Contracts. Updated all relevant application files to use the correct DTO namespaces for Catalogs and MassData. Adjusted _Imports.razor to include new DTO namespaces and removed unused usings. These changes improve code consistency and reduce namespace-related errors.
Deleted DTOs for catalogs, layouts, mass data, and dashboard info from both Application and BlazorWebApp.Models namespaces. Updated DbFirst.Application.csproj to include a new Layouts folder for future organization. No functional code changes in this commit.
Added DbFirst.Contracts as a project reference to both DbFirst.Application and DbFirst.BlazorWebApp, and added DbFirst.Domain to DbFirst.Application. Also, a BOM was introduced in the BlazorWebApp project file. These changes enable shared use of contracts and domain types across projects.
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.
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.
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.
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.
Changed band editor toggle label to "Layout" in both CatalogsGrid.razor and MassDataGrid.razor. Relocated the page size selector in MassDataGrid.razor to appear after the band editor section for improved layout consistency.
Introduce a toggleable "Band-Layout konfigurieren" section in CatalogsGrid.razor and MassDataGrid.razor, allowing users to expand or collapse the band editor UI. Added bandEditorExpanded state to control visibility. Updated CSS to style the new toggle button and its expanded/collapsed states, improving usability and reducing UI clutter.
