public class ProductSearchBlockController : BlockController<ProductSearchBlock>
    {
        private readonly IRepository<Products> _productsRepository;

        public ProductSearchBlockController(IRepository<Products> productsRepository)
        {
            _productsRepository = productsRepository;
        }

        public override ActionResult Index(ProductSearchBlock currentBlock)
        {
            var viewModel = new ProductSearchBlockViewModel();
            viewModel.Products = _productsRepository.All().ToList();

            return PartialView(viewModel);
        }

        [HttpGet]
        public ActionResult OrderBy()
        {
            var viewModel = new ProductSearchBlockViewModel();
            viewModel.Products = _productsRepository.All().OrderBy(p => p.Price).ToList();

            return PartialView("../ProductSearchBlock/Index",viewModel);
     

This is my controller I have a form in the block that hits the OrderBy action however what is returned is the partial file not the page with the block. How can achieve this?

I want to pass in sorted products in the block. When a button is clicked.
