one selected value only in a listbox

[#1]

Hi experts,

is it possbile to modifiy the behaviour of a listbox concerning the "always one selected value" option ?

In my case, one user has to have this option activated, another user not.

Is it possible to realize it ?

Thanks for your help

Hi,

1. I think it is possible in List box layout Conditional option.

2. Use 2 list box for bassed on user type.

See below screen short

Not with only one listbox. You'll have to use two listboxes like Kumar says. Enable the Conditional option for the listboxes and enter and expressions like =if(OSUser()='John',1,0) for the listbox for John and =if(OSUser()='Jill',1,0) for Jill's listbox. If you're using section access the use QVUser() instead of OSUser() or you can add a flag field (for example FlagAlwaysOneSelectedValue) to the section access table and use that field instead in the conditional expression: =[FlagAlwaysOneSelectedValue].
