Controling a ListView - VB.NET

I have a report that can take anywhere from 5-30 minutes to run.  The results are displayed in a listview.  The results are inventory items that either "Pass" or "Fail" a "quantity on hand vs. sales per month" test  (basically, do we have enough widgets in stock based on past sales averages).

Since the results can contain up to 4000 items it would be nice to toggle three displays:
1. All Items that Pass
2. All Items that Fail
3. All Items Regardless

Right now it shows all items, I simply change a subitem in the listview to say Pass or Fail and change the color to red if its a fail.

Is it possible to hide or toggle the results to display like this?

Thanks for your help!!!

I don't understand what you mean by "hide or toggle".  Do you mean changing a sub item dynamically after the ListView item is created?

Sorry for being confusing...

Imagine having a listview of 4000 items (or products).
Each item falls into 1 of 3 categories:  

1. Not Enough on Hand  
2. Enough on Hand
3. More than Enough on Hand (as in, we'll never sell them all...)

So I'm looking at the list of 4000 items and I decide I just want to see items in category #1.

Can I hide items in category 2 and 3 without clearing and refilling the listview?

I hope that clears it up a little bit.  Thanks for your response!!!

Hmmm...you can hide groups, but I don't believe that ListViewItem supports hiding.  

One possibility might be using a custom ListView that supports data binding, and binding the ListView to a filtered DataView.
