This class includes the following properties:

<div class="alert alert-danger @(ErrorVisible? " visible" : " invisible")">@MyError</div>

@code {
    bool ErrorVisible { get; set; } = false;
    string MyError { get; set; }

    void OnUploadError(FileUploadErrorEventArgs e) {
        MyError = e.RequestInfo.ResponseText;
        ErrorVisible = true;
        InvokeAsync(StateHasChanged);
    }
}
