Yes, I did. Here is what I have in the page

<%@ Register Assembly="skmControls2" Namespace="FriendshipCircle.FCAdmin.skmControls2"
    TagPrefix="cc1" %>

and

<cc1:GridView runat="server" ID="ProfilesGrid"

If I would not add this GridView on the toolbox, how would I use this class in my pages?

Also why did he name the class GridView and not some custom SortingGridView?

May be the idea was that having just adding this class to the App_Code all your grids would automatically use this GridView class and not the default GridView?

Would you please clarify this for me, because I think I'm doing something wrong here.

When you tried it yesterday, did you try to create a new project and add it there?

Also I didn't study the Test Project that came with this class, guess it's time to review it too.

Thanks a lot again.
