Thanks for the suggestions.
I like the idea of casting the Integer as an Object and then casting it back
again as it seems to have wider applicability (ie to all the other list
thingies).
Thanks again.

Some other alternatives are:
1. SomeListItem.Data := TObject(MyIntegerID) where MyIntegerID is the key
value of your database record, you can then do Integer(SomeListItem.Data) to
retrieve it back.
2. SomeListItem.SubItems.Add(IntToStr(MyIntegerID)) and make this column
invisible, then you can StrToInt() it back, this way you can store many
extra columns of info onto the TListView (just not showing them).

If am using the listview in report mode and I am not assigning icons to the
records then I sometimes use the imageindex or stateindex property to hold
my database key record value (both properties of type integer)

Subject: [DUG]: Listview Question: where is itemdata.
In vb a Listview object has an Itemdata property which can be used to store
the key value of the listitem which has been read from a database. This
seems to be used in Delphi to hold a pointer to the Listobject. Is there a
really simple way to assign an integer to the itemdata property - so I can
basically have the same functionality as the vb Listbox (ie store the Text
and the ID for the List Item)? Or am I using the wrong component (cannot use
DBLookupList b/c the user needs to select multiple rows).
Seems simple enough - but before wading through how Itemdata property is
used in the VCL I thought I would ask.
Thanks
James Low

I am ownerdrawing a listview, BUT because of this, I need to draw the focus
