FMX ListView with LiveBindings

Question

I am developing an FMX (Android) app using a ListView in Delphi 10.2.3. I have the Listview live(bound) to a ClientDataSet with (Synch->*). This works very well, and any changes in Listview are propagated to the ClientDataSet, including the ClientDataSet's event handlers, such as BeforeUpdate, Post and AfterScroll.

Now when I move the record pointer in the ClientDataSet programmatically, the Listview does not synch with the change. It seems the Livebinding only works "one way" (from the UI to the Dataset).

How can I make the Listview follow the ClientDataSet, the way it does in the VCL when using a DataSource?

// here I expect the see the selected item start at the first item 
// in the UI in index order and move quickly down through the 
// list until it stops at the last one. This doesn't happen. The UI remains
// unaffected.
ClientModule.CDSData.First;
while not ClientModule.CDSData.Eof do
begin
   ClientModule.CDSData.Next;
   Sleep(100);
end;

Answer 1

The easy answer to this question is to perform a

if ClientModule.CDSData.Locate('PKID', VarArrayOf([PKIDValue]), []) then

It seems that while moving the record pointer using CDSData.Next doesn't sync back to the Live(Bound) Listview, using a locate does.
