Table View Item ToggleDetailView

I want to do this myself rather than automatically as I want to have the back button on my own toolbar.

However. If I put AItem.ToggleDetailView(True); in the TabelView's OnItemClick method nothing happens. If I use AItem.ToggleDetailView(False); it is displayed briefly and then goes blank.

I'm living in hope that someone at TMS will reply to the posts that I have made!

Have worked this out myself. Works if I use AItem.ShowDetailMode/HideDetailMode;
