    protected void SelectedFilesChanged(IEnumerable<UploadFileInfo> files) {
        Files = files;
        UploadVisible = files.ToList().Count > 0;

        InvokeAsync(StateHasChanged);
    }

    void OnCancelButtonClick(){
         FirstFile = Files.First();
         MyUpload.CancelFileUpload(FirstFile);
    }

    void OnReloadButtonClick(){
