Notify (“Contact record submitted sucessfully.”,NotificationType.Success)
- Now run the app and save the contact record and you will see the success notification as shown below:

- On Save button in below screen write formula on OnSelect property as:
If (!IsNumeric(DataCardValue28.Text),Notify(“Please enter correct mobile number”,NotificationType.Error))
- Now run the app and save the contact record and you will see the error notification if Mobile Phone value is in string as shown below:
