How to validate phone field on model driven

[MohammedWard]

Hello everyone,

I'm building my first app and I faced a problem on model-driven validation

- Forcing the phone number field to be numbers only

- how to force the number to be 11 exactly

I would really appreciate any advice you might have.

Hi @MohammedWard,

I assume your field type is single line of text. You can easily format to phone by with the Input Mask control. Here are the quick steps:

1. Open your solution that contains that entity and open the main form. Click the "switch to classic" button on the top
2. Select the phone number field and click "Change Properties"
3. Navigate to the Controls tab and click on "Add Control"
4. Select "Input Mask" and click add
5. Pick you field for the Field property
6. Enter the mask (00000000000) for the Mask property. You can also put dashes
7. Ensure the Input Mask control is selected for Web, Phone and Tablet.
8. Save all and publish all customization

Hope this helps!
