Instruct UI - An AI for Blazor UI Generation
## What's implemented
- Region list using a MudDataGrid with hierarchical/child rows that expand to show markets.
- Simple search field and client-side filter for region name.
- Add/Edit dialog implemented with MudDialog and a MudForm that validates the region name.
- Row actions for Edit and Remove; Remove uses a browser confirm via IJSRuntime and shows Snackbar notifications.
## Key components
- MudDataGrid<T>, HierarchyColumn, PropertyColumn, TemplateColumn
- MudTable<T> for child rows
- MudDialog, MudForm, MudTextField, MudButton
- IDialogService, ISnackbar, IJSRuntime
- DTO models: RegionDto, MarketDto, SearchResultDto<T>
## How it works
- Data is stored in-memory in a SearchResultDto<RegionDto> and _displayRegions is bound to the grid's Items.
- The search box uses @bind-Value and ApplyFilter filters _searchResult.Items via LINQ (String.Contains, OrdinalIgnoreCase).
- AddRegion and EditRegion open a MudDialog via DialogService.Show<T> and await dialog.Result; on success the returned RegionDto is merged into the in-memory list and StateHasChanged is called.
- The Add/Edit dialog uses a MudForm reference and calls await _form.Validate() before closing with DialogResult.Ok(Region).
- RemoveRegion calls JS.InvokeAsync<bool>("confirm", ...) to confirm deletion then removes the item and shows a Snackbar.
## Styling
- Uses MudBlazor components and layout primitives (MudPaper, MudStack, MudSpacer) rather than utility CSS frameworks.
- Component props control density, hover, elevation and spacing; responsive behavior follows MudBlazor layout patterns (stack/spacing) but no explicit media queries are present.
## Reuse steps
1. Add the MudBlazor NuGet package and static assets (MudBlazor CSS) to the project.
2. Register MudBlazor services in Program.cs (AddMudServices/AddMudTheme, DialogService, Snackbar) and add required using directives.
3. Copy DTOs (RegionDto, MarketDto, SearchResultDto<T>) and the two Razor components into the project.
4. Ensure IDialogService and ISnackbar are injected where used and IJSRuntime is available for confirm dialogs.
5. Replace the in-memory data with an injected data service or API client and implement paging/sorting if needed.
## Limitations & next steps
- Sample uses in-memory data only; backend API, persistence, and service wiring are required for production.
- Filtering is basic client-side string matching; no paging, server-side filtering, or sorting is implemented (SortMode.None).
- Validation is limited to a required region name in the dialog; add DataAnnotations or custom validators for richer rules.
- Consider adding optimistic updates, error handling, unit tests, and authentication/authorization for delete/edit actions.
