B4J Question How to carry out some action before allowing Listview change of index

You can save the previous index in a global variable and then do whatever you need to do with the previous value.

Thanks Erel. But then the app would still need to prompt user see if the content in textarea needs to be saved (after modification), as well, prevent the display of associated text/content in textarea of the new listview index that was clicked on, or switch back in the index changed event sub. I will test to see if that creates flickers by switching back right away.

Is there a replacing control of listview that can do what I described? i.e. allowing the app to carry out some action before the change of index in a listview like index?

You can use xCustomListView and handle the selection logic yourself.

Thanks Erel. I will give xCustomListView a try.
