question about the listbox

[Anonymous]

Hi,

I'd like to make a listbox where multiple choice is possible but not less the one value must be always selected. Is it possible?

When I try 'Always one selected Value' option in properties, it doesn't allow multiple choice.

Thank you in advance,

Larisa

Hi,

In your example the value Banana is locked, it means that a user can select Banana plus any other brand, it is not possible to clear Banana.

My idea was different. At least one value must be always selected. But it mustn't be a certain value (in your example it is Banana). It can be any one value from all values present. I wanted to alow a user to select any one, two, etc. values, but make it not possible to clear selection if only one value is currently selected.

Ok, see attached example.

Thanks!

I've investigated the properties of your listbox, but I can't understand how you did it.

What functionality lies behind it?

See the OnSelect field trigger of the Product field on the Triggers tab of the Document Properties window.

Hi, Gysbert,

I tried to use your approach in my model, but it doesn't work. I set a trigger action for the field Brand. But it is still possible to clear all brands.

See the file attached.

Why it doesn't work in this example?

See the file attached.

Thank you in advance,
