Hi @joao_guerreiro,

If you only want to allow the user to select a button if the gallery contains 1 record, you could use the following code in the DisplayMode property of the button:

If( //Change galleryName with the actual name of the gallery CountRows(GalleryName.AllItems) = 1, DisplayMode.Edit, DisplayMode.Disabled )

If this solves your question, would you be so kind as to accept it as a solution.
Thanks!

Do you want it to only show one row at a time, but you can still scroll through each record (settings its template size to self.height for vertical and self.width for horizontal)? Or do you only want one record to be in the gallery (this would be changing its datasource to only return one record)
