Tree Grid View Filtering

Hello,

I've got a multi-level BOM that I'd like users to be able to filter by Name or Part Number.  I followed the Query Element Builders Guide and the blog post "Filter a Tree Grid View with Parameters"; however it only works with the parameters at the top level.

So if for instance, I've got a part (top level) with a Name of "Part_1" and I use the parameters on the TGV with that, it filters fine.  But if I have a sub-part to that, with say a name of "Part_2" and I use the parameters on the TGV to that item, nothing shows up.

I'm assuming the problem is in the filter condition... (Name LIKE $name) AND ([Part Number] LIKE $item_number)

Can anyone help?
