Hi All,

I am trying to link a multi-selection list box with a file item, but can't work out how to save and retrieve the selections. The list box gets data from a query and is supposed to store an ID number for each selection. I have tried linking to a text field, and although the box shows a multi-selection, only the first selection in the box is saved.

What am I missing please?

Cheers

Pete

Hi Peter,

AFAIK, there is no way to link a multiselection anything the way you are describing. The closest is the possibility to link a multiple checkbox to an ARRAY o items in the files.

So you will need some code.

If the list has a limited number of choices, then you can reuse some code available in WXEDM (made for multiple checboxes): I created a function that transforms it in binray values (1/2/4/8/....) and back.

If the list can have ANY number of choices, then you need a secondary file

Best regards

Thanks Fabrice, that was the conclusion I was starting to draw!

Cheers
