Filling form fields based on specific record in data source

Posted on by Community Power Pla... Microsoft Employee

I am looking to bring information from a third party system (assume a Data Source already connected to the app) and fill in fields based on a user's input.

As an example, the user may enter a username into a text box and click on a button, that will then pull the user's details from the data source and populate the Phone Number and Email Address text boxes. The user can then change those fields if they wish.

I am trying to make this work with a combination of collections, context variables etc with the value stored in the "Default" field of the text box (and using Reset when the user changes the username), but finding this quite challenging. Is there a better way of doing this?

Hi @Anonymous ,

I suggest you to change these fields by EditForm rather than custom text box, then there is no need to worry about Default property.

1. Use LookUp function to retrieve back the record from the data source

Button.OnSelect: Set(SelectedItem, LookUp('Data Source',username=TextInput1.Text));EditForm(FormName)

2. Bind the Form to the SelectedItem

Form.Item: SelectedItem

3. Add a SubmitButton, set OnSelect: SubmitForm(FormName)

Hope this helps,

Sik
