I am having difficulties finding relevant information regarding listview sorting and grouping. The following picture shows the listview I am trying to sort/group.
Listview.jpg

I am attempting to group not only by "Part Type" but by also to group certain part choices together (when a motor part is chosen that parts as well as matching motor parts to complete the setup are pulled from the DB and these should be grouped together by each choice rather than by "Part Type").

I have tried MSDN, CodeGuru, DreamInCode, and have Googled the topic for 2 days but have not found a relevant example for databound item listview grouping/sorting.

If you have any leads for me they would be greatly appreciated.

Thanks!
