MudBlazor Theme in ABP Blazor WebAssembly PART 2

Introduction

This sample ABP Blazor WebAssembly project shows how to replace built-in Notification service to display notifications with MudBlazor's Snackbar component. The source code is avallable on GitHub.

5. Make Sure You Have Completed PART 1

This project is built on top of MudBlazor Theme in ABP Blazor WebAssembly PART 1. Therefore, you will first need to complete the steps shown in PART 1 to continue following the steps listed here.

6. Add MudBlazor Snackbar Support To MainLayout

Open MainLayout.razor, add <MudSnackbarProvider /> and remove <UiNotificationAlert />. The final content of the file should look like this:

@inherits LayoutComponentBase

<MudThemeProvider />
<MudSnackbarProvider />

<MudLayout>
    <MudAppBar Elevation="8">
        <MudIconButton Icon="@Icons.Material.Filled.Menu" Color="MudBlazor.Color.Inherit" Edge="Edge.Start" 
                       OnClick="@((e) => DrawerToggle())" />
        <Branding />
        <MudSpacer />
        <NavToolbar />
    </MudAppBar>
    <MudDrawer @bind-Open="_drawerOpen" ClipMode="DrawerClipMode.Always" Elevation="8">
        <NavMenu />
    </MudDrawer>
    <MudMainContent>
        <MudContainer MaxWidth="MaxWidth.False" Class="mt-4">
            <PageAlert />
            @Body
            <UiMessageAlert />
            <UiPageProgress />
        </MudContainer>
    </MudMainContent>
</MudLayout>

@code 
{
    private bool _drawerOpen = true;

    private void DrawerToggle()
    {
        _drawerOpen = !_drawerOpen;
    }
}

7. Replace Notification Service

In Volo.Abp.AspNetCore.Components.Web.BasicTheme project, create a folder named Services. Create MudBlazorUiNotificationService.cs file in this folder, and add the following content:

using System;
using System.Threading.Tasks;
using MudBlazor;
using Volo.Abp.AspNetCore.Components.Notifications;
using Volo.Abp.DependencyInjection;

namespace Volo.Abp.AspNetCore.Components.Web.BasicTheme.Services;

[Dependency(ReplaceServices = true)]
public class MudBlazorUiNotificationService : IUiNotificationService, IScopedDependency
{
    private readonly ISnackbar _snackbar;

    public MudBlazorUiNotificationService(ISnackbar snackbar)
    {
        _snackbar = snackbar;
    }

    public Task Error(string message, string title = null, Action<UiNotificationOptions> options = null)
    {
        _snackbar.Add(message, Severity.Error);
        return Task.CompletedTask;
    }

    public Task Info(string message, string title = null, Action<UiNotificationOptions> options = null)
    {
        _snackbar.Add(message, Severity.Info);
        return Task.CompletedTask;
    }

    public Task Success(string message, string title = null, Action<UiNotificationOptions> options = null)
    {
        _snackbar.Add(message, Severity.Success);
        return Task.CompletedTask;
    }

    public Task Warn(string message, string title = null, Action<UiNotificationOptions> options = null)
    {
        _snackbar.Add(message, Severity.Warning);
        return Task.CompletedTask;
    }
}

The code shown above automatically replaces the built-in IUiNotificationService service. To learn more about this mechanism see Overriding Services.

Now, modify Index.razor file to test MudBlazor style notifications:

@page "/"
@using Volo.Abp.AspNetCore.Components.Notifications
@inherits BookStoreComponentBase
@inject AuthenticationStateProvider AuthenticationStateProvider
@inject IUiNotificationService NotificationService

<div class="container">
    <div class="p-5 text-center">
        <Button onclick="@(async () => { await NotificationService.Success("Hello, World!"); await NotificationService.Warn("Something went wrong!"); })">
            Show Notifications!
        </Button>
    </div>
</div>
