Still stuck on this.. Can't find what is wrong. If any additional information is needed I'd be happy to give them cause any suggestion is more than welcome at this point..

Hello,
Yes and yes to both questions.

At first we tried this way to call the resources correctly
<asp:Label ID="lblCart" runat="server" resourcekey="LBLCART" Text="Cart" AssociatedControlID="ddlCart"></asp:Label>
 
Then we tried this way
lblCart.Text = LocalizeString("LBLCART"); (LBLCART.Text = Cart in View.ascx.resx)

With both ways the resources were displayed correctly when the page loaded. But when a POSTBACK on the page was made, then the resources wouldn't load correctly and appeared as they were in the default language.

Then we used this way
lblCart.Text = Localization.GetString("LBLCART", localResourceFolder, currentLocale);

And this was the only solution that worked and displayed the resources correctly after the POSTBACK.

Is this the correct way or is there another way to approach this?
