On check only a single check box in a gallery making all other checkbox inactive.

Can we on check only one check box instead of multicheck boxes in a gallery which is having number of checkboxes. When, on chekc a checkbox, gallery should not allow to on check another check box. I just want to send only one check box data to my table. Can anybody help on this?

I'm trying to accomplish something similar.  I don't see how the marked solution helped. This will disable checkboxes, the idea is to clear them not disable them.  Any help?

Hey All,


I came up with my own way that seems to be working, after I couldn't find an answer on here.


This is to have a checkbox in every item in a gallery, but only allow one item in the Gallery to be checked at one time:

1) add the checkbox to the gallery

2) Set up a variable to capture the ID of the currently checked Item - VARCheckedItem

3) Set OnCheck (on the Checkbox Properties) to be: Set(VARCheckedItem, ThisItem.ID); Reset(Checkbox)

4) Set the Default (on the Checkbox Properties)  to be: If(ThisItem.ID = VARCheckedItem, true, false)

Happy Days 😄
