Author	SHA1	Message	Date
OlgunR	6ac48a472d	Simplify Fluent theme registration in App.razor Replaced custom Fluent theme registration (with ApplyToPageElements set to true) with the default Fluent theme registration, removing unnecessary property customization for a cleaner setup.	2026-04-15 14:16:35 +02:00
OlgunR	96dfd5b3c6	Set default values for CarouselData string properties Initialized Source and AlternateText with empty strings in the CarouselData class to prevent potential null reference issues.	2026-04-15 14:16:03 +02:00
OlgunR	810771f385	Remove auto-refresh of dashboards in OnParametersSetAsync 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.	2026-04-15 14:08:14 +02:00
OlgunR	a0e0d7ed03	Centralize API error handling in ApiClientHelper 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.	2026-04-15 13:55:57 +02:00
OlgunR	39cb63a78d	Refactor UpsertAsync to use ApiResult for error handling 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.	2026-04-15 11:27:48 +02:00
OlgunR	7d08923444	Remove unused bandEditorExpanded field from BandGridBase 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.	2026-04-15 11:01:22 +02:00
OlgunR	11374347d3	Refactor band editor into reusable BandEditor 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.	2026-04-15 10:57:28 +02:00
