Limit the number of items one can select in a listbox

[#1]

Hi All,

I have a list box with 10 items, but I want to limit the user to be able to select only three items at any given time.  Is there a way for me to do this?

Thanks,
Carlos

Carlos,

maybe 3 listoboxes with "always one selected" in alterante states?

Or trigger which checks numer of selected items ....

[#3]

Can you disable the ability to select items in a listbox through expressions?  Let's say the user has selected three items, I can have a trigger that prevents them from selecting additional items once we reach the three item threshold?

Hi Carlos,

If possible you can try this in your listbox->properties->general->Field -go to expression and add =if(GetSelectedCount(<Your Column Name)>3,'No Data to Show',<Your Column Name>)

Regards,

Tom
