ah, you are back again...

the suggestion was to use one of the multi select examples
what did you try?
and you always can add a checkbox which says "select all detail data"

i just don't understand the concept for checking using the multi select and even if it worked, how can i make select all?

even the extension example is only for components not listviews

Is there a way to add a checkbox and to make it connected with the listview selections?
so when i mark on the checkbox, all listview selections can be selected

92

@ABG, the author of that solution might be able to help...

As always first try to understand the concept in a small example project before including it in your project

AI2 ListViews were not designed for keeping track of multiple selections.

That is left for the app author to do, behind the scenes, in a data base or list(s).

You can represent multiple selections in different ways, depending on how they help achieve the objectives of the app.

It is usually better to pick one method and not mix them.

  1. Keep a separate list of the items that was selected. This is good for short selection lists out of a much larger list. You could supplement this with a list of items that were NOT selected.

  2. Keep two parallel lists of items,
    a. A true/false value to indicate selected
    b. The item to be selected or not

What you show in one or more ListViews should just be a reflection of what you keep behind the scenes.
