Hide rows in listview?

[Chris]

Is it possible to hide specific rows in a listview?
I currently have a listview in details view and the user can select
multiple views which shows the listview items matching the selected
criteria. I currently populate the listview from a List<> each time the view
is changed, but was curious if it would be possible to just hide rows which
do not match the criteria.
Any help would be appreciated.

Unfortunately I think the only thing you can do is remove it. Of course,
you could keep it in a separte List<> so you can put it back - you don't
have to destroy the ListViewItem.

That's what I've been doing, but I have a lot of possible search parameters
and removing/repopulating the listview from a List<> for all these has led
to a rather large listviewPopulate() method. I was just curious if there was
any way to reduce it/make it more efficient .

Well there is one thing you could try... ListView in .NET 2.0 supports an
OwnerDraw. I'm not sure how much trouble that would be. Maybe you could
somehow call the default drawing mechanisms?
