Trouble making synchronized virtual ListViews

[RichardAD 0]

Any help would be greatly appreciated.

 

I"ve been trying (for too long) to get two virtual ListViews (report mode) with the same back store to have synchronized selections.  I either get stack overflows, or invalid address, or infinite looping.  I also want to be able to select the same index in both ListViews for a given input but the cross selected cross wiring is not helping.

 

I thought it would be some simple flags, but it's turning out to be a nightmare.  To simplify things, the sample uses a random number for the back store.

 

main.pas

main.dfm

There are two things missing:

1. To make the selection of the other view visible, the HideSelection of the listview has to be false.
2. OnSelectItem is also triggered when an item is unselected. You should call Clear for the numberbox and ClearSelection for the listview then.
