Hi there,

I need to build a powerapp to edit some rows of a sharepoint list. The list is builted as follow:

I've built with success a multi Gallery (the gallery wich shows the "Origine" values is inside the Gallery wich shows the "Dosatore". The toggles are used to turn in "true" or "false" the "Attivo" filed.

I need a logic which allows me to set "false" to all the toggles of a "Dosatore" but the one I selected. This because I'm allowed to have only 1 origin for each Dosatore.

This is a legit situation:

Any Idea to do that without using powerAutomate?

Thanks.

Hi Calcioscacchi,

You can add the following code on the OnSelect property of your Toggle control. This won't let you select a toggle once a toggle has been selected. Please note the default property of the Toggle is set to False.

If( CountRows( Filter( GalleryName.AllItems, Toggle1.Value = true ) ) > 1 , Reset(Toggle1), false )

Hope this helps.

Kind regards,

Nandit

Hi @Nandit,

The Default property is setted as the value of "Attivo" Field in the List, So I suppose that your solution will fail with this constrain:

And the On Select property will also update that value

This ois my actual strategy:

Default Property:

ThisItem.Attivo

On change property:

Patch( 'Tracelot - Origini dosatori'; LookUp( 'Tracelot - Origini dosatori'; ID = ThisItem.ID ); {Attivo: Toggle2.Value} )

On check property:

ClearCollect( colOrigini; Filter( 'Tracelot - Origini dosatori'; Linea = Radio1.Selected.Value && Dosatore = Title1.Text && Origine <> Subtitle4.Text ) );; ForAll( colOrigini; Patch( 'Tracelot - Origini dosatori'; LookUp( 'Tracelot - Origini dosatori'; ID = ThisItem.ID ); {Attivo: false} ) );; Refresh('Tracelot - Origini dosatori')

The idea is to collect all the rows with same "linea" and "dosatore" that I don't turn on, then patch them with false value on "Attivo".

When I run my code, something like a loop egins, and it's over only when all the toggles are off. I can't figure it out why....
