Product: Power Apps, SharePoint
Device & OS: not provided
Scenario: Viewing or editing an existing item in a Power Apps form integrated with a SharePoint list.

Before you start

Ensure you have the necessary edit permissions for the Power Apps form and verify that the specific SharePoint list item actually contains valid phone number data.

Solution 1Recommended

Verify Data Card Bindings and Default Properties

Check if the data card is properly bound to the correct SharePoint column and ensure custom formulas are not overriding the default value.

In many cases, a blank field in an integrated Power Apps form is caused by a disconnected DataField property or an incorrect Default setting on the input control. Re-establishing this connection forces the app to pull the existing data from SharePoint.

Open the form in Power Apps Studio

Navigate to your SharePoint list, click on 'Integrate', select 'Power Apps', and then choose 'Customize forms' to open the editor.

Select the problematic data card

In the Tree view on the left, expand the form and click on the specific data card corresponding to the Phone Number field.

Verify the DataField property

Check the advanced properties of the selected data card to ensure the DataField property exactly matches the internal column name of your SharePoint list.

Check the Default property

Select the text input control inside the data card and ensure its Default property is set to 'Parent.Default'.

Verify Data Card Bindings and Default Properties

Community Support: If the card is correctly configured but remains blank, the issue might require deeper troubleshooting. Consider posting your scenario in the official Power Platform Community.

Frequently Asked Questions

Why is my entire Power Apps form not showing existing SharePoint data?

This generally happens if the form's Item property is not configured correctly. For integrated SharePoint forms, the Item property should usually be set to 'SharePointIntegration.Selected' to display the data of the currently highlighted list item.

Can I use custom formatting for the phone number field in Power Apps?

Yes, you can use the Text function or apply custom formulas to format phone numbers (e.g., adding dashes or country codes). However, ensure these formulas are applied to the display properties and do not break the two-way data binding required to save data back to the SharePoint list.

Does the SharePoint column type affect how Power Apps displays phone numbers?

Yes. If the SharePoint column is set to 'Number', it may strip leading zeros or fail to display properly if the formatting contains special characters. It is highly recommended to use a 'Single line of text' column in SharePoint for storing phone numbers.
