In an ASP.NET MVC application I have a CartController
with this AddToCart
action:
public RedirectToRouteResult AddToCart(Cart cart, decimal productId,
string returnUrl)
{
Product product = productsRepository.Products
.FirstOrDefault(p => p.prodID == productId);
cart.AddItem(product);
return RedirectToAction("Index", new { returnUrl });
}
When a user submits a POST request ("Add to Cart" button) to this action from a plain ASP.NET MVC view, everything goes well: the Product is added to the Cart and the user is automatically redirected to a Cart/Index
page.
If the product is submitted from a Silverlight app (which is inside an ASP.NET MVC view) it is successfully added to the Cart as well, but the there is no redirection in this case.
What is the problem? Maybe it is due to the fact that all requests from a Silverlight are asynchronous (if I'm not mistaken), and the request from a general ASP.NET MVC view is synchronous by nature? How it can affect the redirection?
In any case, how this problem could be solved?
Edited (added):
My code for sending a post request from a Silverlight app:
//first build a "paramstring" in the format "productId=126504" and then post it using this
WebClient wc = new WebClient();
wc.Headers["Content-type"] = "application/x-www-form-urlencoded";
wc.UploadStringAsync(new Uri("http://localhost:10930/Cart/AddToCart"), "POST", paramstring, "http://localhost:10930/Products");
