Conditional column validations
Using Crow Canyon Forms Manager App, we can configure a conditional column validation in a SharePoint online site.
Use Case: "Resolution Notes" field should be a required field while closing a ticket (Tickets list; Request Status = Closed).
Go to Application Administration –> Crow Canyon Nitro Apps –> Crow Canyon Forms Manager app –> Select Tickets list –> Go to Column Validations section –> Select "Resolution Notes" column.
Configure new validation with a condition like below.
Note: This validation does not apply for the tickets which are being closed using a custom action like "Close" button in the ticket ribbon or in "Quick Edit" mode. This validation will be applied only in the standard SharePoint forms.
