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.
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.
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.
