InfoPath Dev

i have a view containing: 2 cascading list (with single choice) - list box: Zone {Europe, Asia, ... Multizone} - List box: country {France, Romania,...,MultiCountry} i would like if it possible when: Choice zone=Multizone and Choice country= MultiCountry transform List box MultiCountry to multi choice list Thanks for helping

Its not straight forward to actually change a control in InfoPath.  What I would recommend is to insert both a list box and multiple select list box and then use rules to hide one of them based on the selection of Choice Zone.  Each of the controls requires to be bound to two different type of fields, so make sure that when you submit the form whatever is looking at those fields is looking at the right now.  Hope that makes sense.  Let me know if you need me to elaborate some more.

Thank you Mr "Anson Hidajat" I see clearly now, But I’m still confusing, I mean that we must use 2 fields for the same data? thank You again

You can have 2 controls bound to the same field in the data source.  For example, if you right click a control and click Change Binding, you can select a field that is already bound to another control that is on the form.  This means that the both controls display the same set of data.
