Should I created the panel and and repeat it onto the scrollview in code (as in the example) ?
Or could I be using the designer (and the script option) so I can design it visually ? If so: How should this work ? Should I design the scrollview using the designer, put a single panel onto it (with the textboxes etc) .. .and then write in code a way to have this panel repeated ?
In the link in your post you find a new version of the example program, ScrollViewNLayouts1, with a Panel layout.
You should define the ScrollView in a layout file but define a separate layout file for the Panel.
