I’m trying to define a component which acts as a bootstrap alert wrapper.

BootstrapAlert.razor

<div class="alert alert-@AlertType d-@(string.IsNullOrEmpty(Message) ? "none" : "block")" role="alert">
    @Message
</div>

@code {
    [ParameterAttribute]
    private string AlertType { get; set; } = "info"; // Default alert type
    [ParameterAttribute]
    private string? Message { get; set; }

    // Method to update the alert type and message
    public async Task ShowAsync(string alertType, string message)
    {
        AlertType = alertType;
        Message = message;
        await InvokeAsync(StateHasChanged);
    }

    // Method to hide the alert
    public async Task HideAsync()
    {
        Message = null;
        await InvokeAsync(StateHasChanged);
    }

     protected override async Task OnParametersSetAsync()
    {
        //Message is ALWAYS null here
        await base.OnParametersSetAsync();
    }

}

Page:

<form class="row" @onsubmit="SubmitForm" @onsubmit:preventDefault>
  <Alert @ref=SaveAlert></Alert>
  <button type="submit">Save</button>        
</form>

@code {
    private Alert? SaveAlert;

private async Task SubmitForm()
{
    try
    {
        await SetIsLoading(true); //DISPLAYS A LOADING SPINNER

        if (SaveAlert != null) await SaveAlert.HideAsync();

        //.......

        if (SaveAlert != null) await SaveAlert.ShowAsync("success", "OK");
    }
    catch (Exception ex)
    {
        if (SaveAlert != null) await SaveAlert.ShowAsync("danger", ex.Message);
    }
    finally
    {
        await SetIsLoading(false);
    }

    StateHasChanged();
}

}

The alert component is never updated, at “OnParametersSetAsync” the “Message” parameter is always null.

I have tryed not async versions of the methods, putting “StateHasChanged” everywhere, not calling the “Hide” method, also removing the [ParameterAttribute] attributes so it were used as a regular variables but nothing seems to work for me

I’m pretty new at blazor so I don’t know what else could be relevant. I’m using the app as RenderMode=”Server”

What I’m doing wrong?
