From: JD on 25 May 2010 08:23 May be this an old subject.... I'm trying to do a simple test (change the position of item 2 to the first) but I can't do it! METHOD PBMove( ) CLASS dwX LOCAL oPoint AS Point oPoint := oLV:GetItemPosition(1) oLV:SetItemPosition(2,oPoint) SetItemPosition should show the item 2 on the first position, right? So what I missing? Can you help me? Thanks. Jairo

I re-fill the data in the listview (from the data-base) every time the data is changed. That certainly isn't done by one of the listview methods. It will take very short time and you will probably have a separate method to fill the list-view so it's also not much work to code it like that.
