Here's the problem, I have two listviews. ListView1 has the items that needs to be checked (a pre-loaded list of items). When checking the items, all items from actual physical inventory are thrown to ListView2. Now, the program must compare all items that were found from checking or those that are placed on ListView2 with ListView1 and all items that are on listview2 will be deleted from ListView1 , so the items that should be left on listview1 should be the ones considered as missing.

Listview1
Item1
item2
item3
item4
item5

ListView2(item found)
item5
item1
item3

ListView1 content after comparing
item2
item4

If you have any other means like highlighting the items that are missing instead of deleting them from listview1, I will really appreciate it

Thank you so much!
