Re: [DUG] Validating a TListItem exists

Mon, 31 Jan 2011 15:27:23 -0800

Hi

Sorry about the delayed response.  Without knowing your system and why you cant guaranty an item is deleted from the TList at the same time as the ListView an option might be to use the listview in ownerdata mode so that the listview is populated from the TList.  Might be a bit of work to recode but as a bonus the Listview will work much, much faster with large datasets.

Thanks
Rob

I’m storing some TListItem’s in a TList. 
            Some of these items could be removed from the listview at
            some stage.  I know the items should be removed from the
            TList when removed from the listview, but don’t ask.

        
 

        
Is there a simple method to determine if
            a listitem reference is still valid and exists, or do I need
            to use listview.items.indexof which could be slow.

        
 

        
Cheers.
