I ran into a problem whereby the list of filter attributes was not being grouped correctly under the "Filter by Attributes" area of ProductSpecificationFilter.ascx.cs
I saw this:
Filter by Attributes
Color
Black
Make
Ferrari
Color
White
Make
Holden
instead of seeing:
Color
Black
White
Make
Ferrari
Holden
So either amend the sproc: [Nop_SpecificationAttributeOptionFilter_LoadByFilter] and orderby SpecificationAttributeName first then by DisplayOrder
or in code I did the following: (ProductSpecificationFilter.ascx.cs)
--------------------------------
protected SpecificationAttributeOptionFilterCollection getNotFilteredSpecs()
{
//get all
SpecificationAttributeOptionFilterCollection result = SpecificationAttributeManager.GetSpecificationAttributeOptionFilter(this.CategoryID);
//remove already filtered
SpecificationAttributeOptionFilterCollection alreadyFilteredOptions = getAlreadyFilteredSpecs();
foreach (SpecificationAttributeOptionFilter saof1 in alreadyFilteredOptions)
{
var query = from s
in result
where s.SpecificationAttributeID == saof1.SpecificationAttributeID
select s;
List<SpecificationAttributeOptionFilter> toRemove = query.ToList();
foreach (SpecificationAttributeOptionFilter saof2 in toRemove)
{
result.Remove(saof2);
}
}
var sortedList = new SpecificationAttributeOptionFilterCollection();
sortedList.AddRange(result.OrderBy(i => i.SpecificationAttributeName).ToList());
return sortedList;
}
--------------------------------
Unless of course this is by design
