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.
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.
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.
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
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.
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.
