Blazorise Version

1.7.1

What Blazorise provider are you running on?

Bootstrap5

Link to minimal reproduction or a simple code snippet

I cannot for the life of it get Notifications to work a Blazor 9 Server App. I don't see any exception in the Visual Studio debugger or in the browser console. But I don't see notifications either. I have created a small standalone demo to reproduce the problem by following these steps:

  1. Create a new Blazor Project using Visual Studio's Blazor Web App Template (.NET 9)
  2. Implement the Blazorise integration quick start: https://blazorise.com/docs/start
  3. Setup the Blazorise Notification service per instructions here: https://blazorise.com/docs/services/notification-provider

What is actually happening?

Nothing.

What browsers do you see the problem on?

Microsoft Edge, Chrome

It happens because you have rendermode InteractiveServer defined on a page level. And NotificationProvider is placed on a "global" level. So, it will never be re-rendered by the page.

Try this:

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <base href="/" />
    <link rel="stylesheet" href="@Assets["app.css"]" />
    <link rel="stylesheet" href="@Assets["BlazorWebApp.styles.css"]" />
    
    <ImportMap />
    
    <link rel="icon" type="image/png" href="favicon.png" />
    
    <HeadOutlet @rendermode="InteractiveServer" />

    <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-QWTKZyjpPEjISv5WaRU9OFeRpok6YctnYmDr5pNlyT2bRjXh0JMhjY6hW+ALEwIH" crossorigin="anonymous">

    <link href="_content/Blazorise/blazorise.css?v=1.7.1.0" rel="stylesheet" />
    <link href="_content/Blazorise.Bootstrap5/blazorise.bootstrap5.css?v=1.7.1.0" rel="stylesheet" />
    <link href="_content/Blazorise.Snackbar/blazorise.snackbar.css" rel="stylesheet" />
</head>

<body>
    <Routes @rendermode="InteractiveServer" />
    <script src="_framework/blazor.web.js"></script>
</body>

</html>

Thanks @stsrki. Out of curiosity, can you explain why it works that way? And what the recommend fix is?

I could, but I'm not that good at explaining stuff :)

Here is the article from Jon that did it quite well https://jonhilton.net/blazor-web-app-interactivity-choices/
