I'm having a simular problem.

Would really just like to have the user choose a currency at the top of the page.

If at that time, there is something in the basket, it's ok to reset the basket.

I really just need that xslt extension method called "ChangeCurrency()" for the current session!

Cheers,

Mads

@Przemek:

If you want to select currency based on different method than the current catalog you can override IPricingService and have that select currency based on a customer choice.

There's a sample on the forum that shows you how to override IPricingService. Your logic would of course be different and look for maybe a cookie with the customer selection in or a choice on the member profile.

@Mads:

There's no mechanism for changing currency via XSLT today, but you can use .NET to do it like so:

var purchaseOrder = SiteContext.Current.OrderContext.GetBasket().PurchaseOrder;
purchaseOrder.BillingCurrency = Currency.SingleOrDefault(x => x.ISOCode == "USD");
purchaseOrder.Save();

Naturally you only want to do this if the basket is empty. Prices in the basket will not change automatically with the changed currency. 

Hey Søren,

This works like a beauty in the basket, but how about changing the currency in the XML i get from GetCategoryById() xslt extension method?

Thanks in advance!

You'll have to change the PricingService to make that happen (so some .NET required).

Basically you want IPricingService to reflect the choice a customer makes on the site, which means swapping out the default price engine with your own.

What I'd do is the following:

1) Grab the currency choice from the user and put that in a cookie

2) Override the IPricingService to read the choice

3) Load up the proper price group based on the choice

This forum post shows you how to do it albeit with a different end goal.
