ListView flicker

I am having problems with a ListView flickering whenever I add to it, or change colours of items within the ListView (for highlighting purposes).

Is there any way to prevent this?

Try apply LockWindowUpdate  API before and after your process, like:

Private Declare Function LockWindowUpdate Lib "user32" Alias "LockWindowUpdate" (ByVal hwndLock As Integer) As Integer

then..

..
LockWindowUpdate ListView1.Handle.ToInt32()
'Do your process here..
LockWindowUpdate 0
..

Hope this helps

Use begin and end Update commands on the listview:

me.listview1.BeginUpdate()

'Perform actions
....

me.listview1.EndUpdate()

Hi hairybarbarian:
Bad news.
This question has been asked before (even by myself 500 point question)
Unfortunately no acceptable answer is given (in my case there was no answer at all), and eventually the question gets deleted.
In my opinion it is a M$oft bug. Any change to the listview causes a redraw of the whole grid, which causes the flicker.
