Checkbox inside Gallery None of the Above with SharePoint List

Posted on by rcalonge

I have sharepoint list with the following records

Title
1. ItemA

2. ItemB

3. None of the Above

I created a gallery with checkbox on it to populate this list, Is it possible to uncheck/unselect checkbox ItemA and ItemB if None of the Above is selected and vice versa (uncheck none if either ItemA or ItemB is selected?

I know it's possible if "None" is outside the gallery you just reset the checkbox but I want to know if this is possible if checkbox is inside a gallery.

I manage to get the collection working with this scenario on OnCheck but I'm having a hard time doing it on the interface side

If(
 ThisItem.Title = "None of the above", // if none
 ClearCollect(colSymtomChecker, ThisItem),
 RemoveIf(colSymtomChecker, Title="None of the above")
)

Hi @rcalonge ,

Do you want to change the checked state of the Check Box Control based on the value of the Title column?
I have made a test for your reference.

1. Here is my SharePoint list.
2. Add a Check Box Control to Gallery Template and apply the following formula on its Default property as:
If(ThisItem.Title="ItemA"||ThisItem.Title="ItemB",true,false)
