Radzen Components

Radzen Blazor replaces the legacy Kendo UI JS components. The core library is free (MIT license).

Component	Usage
`RadzenDataGrid`	Search results and history tables
`RadzenDropDown`	Work center, operator selection
`RadzenAutoComplete`	Item number lookup with search
`RadzenDatePicker`	Date range selection
`RadzenButton`	Form actions
`RadzenCard`	Layout containers
`RadzenNotification`	Toast messages
`RadzenProgressBar`	Search progress indication

Program.cs Configuration

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("#app");

// HTTP client for API calls
builder.Services.AddScoped(sp =>
    new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

// API clients
builder.Services.AddScoped<SearchApiClient>();
builder.Services.AddScoped<LookupApiClient>();
builder.Services.AddScoped<AuthApiClient>();
builder.Services.AddScoped<StatusHubClient>();

await builder.Build().RunAsync();

SignalR Client

The StatusHubClient connects on login and subscribes to status updates:

public class StatusHubClient : IAsyncDisposable
{
    private HubConnection _connection;

    public event Action<SearchStatusUpdate> OnStatusChanged;

    public async Task ConnectAsync(string baseUrl)
    {
        _connection = new HubConnectionBuilder()
            .WithUrl($"{baseUrl}/hubs/status")
            .WithAutomaticReconnect()
            .Build();

        _connection.On<SearchStatusUpdate>("StatusChanged", update =>
        {
            OnStatusChanged?.Invoke(update);
        });

        await _connection.StartAsync();
    }
}
