Hi @Gottijay1999

You could use Reset(ComboBoxX) in the gallery but that will remove all of the selected items and the user would have to reselect them from the collection.

@Drrickryp I was looking in the way of a symbiotic relationship between the gallery and the combo box, without the user having to reselect items if they are deleted.
is it possible?

@Drrickryp actually your idea was perfect, i just need to put the collection in the defaultselecteditems property, which means that whenever you reset you get the current value of collection selected.

thank you
