Hi, I'm using ABG code for displaying an check a long list, but after a pick the listview is refreshed and goes to top, how can I go to the last selected item ?

The ListView does not have blocks for that.

Workarounds:

  • Add Labels before the ListView with SelectionIndex and Selection value for handy reference
  • Rearrange the Elements list so the latest selection is on top, at slot 1 (copy to temp list, copy Selection to temo variable, remove SelectionIndex from temp list, inset Selection temp to slot 1 of temp list, reload Elements from temp list.)

No extensions for that ? I don't like your Workarounds, maybe with tableview or tableviewer ?

I don't like extensions.
Sorry!
