I'm in the throws of getting my website ready to go live and have just spent an hour trying to figure out why my custom product control descriptions are no longer showing in the basket.
All I was getting was the name of the custom product and no description, the description being the important bit with the custom measurements, etc.
For anybody else struggling with the same issue, it appears that somewhere in between v2.5 and v2.6, the code at line 223 in BasketView.ascx was changed from:
<asp:Literal ID="litVersionName" runat="server" Text='<%# Server.HtmlEncode(Eval("VersionName")) %>' />
to:
<asp:Literal ID="litVersionName" runat="server" Text='<%# Server.HtmlEncode(Eval("VersionName")) %>' Visible='False' />
Remove the Visible='False' and all will work again as intended. Changing the code back doesn't appear to alter the Basket view for non-custom products so not entirely sure why it was changed in the first place.
Anyhow, hope the above helps someone.
