Using Sort, Distinct, Filter together for combo box Items– Canvas Apps (Dataverse)

Just sharing a simple example of applying a formula to the Combo box Items property, which includes Sort, Distinct, and Filter (If).

Below is our Combo Box bound to a lookup field of type Customer. If Contact is the option selected in the radio control, we want to show Contact’s Full Name sorted else Account’s Account Name field.

If( radioBtnCustomer.Selected.Value = "Contact",
    Sort(Distinct(Filter(Contacts,Status = 'Status (Contacts)'.Active),'Full Name'),
        Value,
        SortOrder.Ascending
    ),
    Sort(Distinct(Filter(Accounts,Status = 'Status (Accounts)'.Active),'Account Name'),
        Value,
        SortOrder.Ascending
    )
)

The result –

Also to clear the selection in the combo box when the user changes the option from contact to account and vice versa we can use the Reset function.
