Is there a way to hide a row in a listview? As the listview is being populated with rows of data some of them I want to keep hidden from the end user but still in the listview to use later in the program. I could store that data in an array but now I am more curious of how to hide a row in a listview

You cannot hide listview items using the standard API for the simple reason that it would be a nighmare to manage internally. You could have a custom draw to enable you to do this but managing it is difficult.
Routines which tell you which item is at a certain point may or may not work since the simple way is y coordinate divided by height of list item. But if you have missing items, that doesn't work so it becomes a sequential search which is a bad excuse for a fast machine.
Switching between detailed view and iconified view may be a problem too for the same reason. Which item is at position x, y? A simple calculation will work it out but not if there are items missing.

>it would be a nighmare to manage internally
Whilst it is true that there is no API call or object method that allows this, I'm not sure that it would be a nightmare to manage (if such a call existed). Surely all Microsoft needed to have built in would be a Visible property for a ListItem to accompany the already existing Gghosted property? They'd do all the nasty management for you.
But yes, the only way (that I am aware of) to achieve it is to create an ownerdraw ListView, and that only works in Report View ...
