Modern Combobox: DefaultSelectedItems with people picker

(0) Share

Report

Posted on by nok

Hey!
I'm trying to use a modern combobox that displays the email of the selected user based on a variable that retrieves the email of the Project Leader from a "Person" column in my Sharepoint list.

When I use the variable "varSelectedProject.Leader.Email" directly in a label or a textbox, it shows the email correctly. However, when I insert the same variable in the combobox's DefaultSelectedItems field, it shows an error saying "it expects a value compatible with Items". My combobox properties are as follows:

DefaultSelectedItems: {Value:varSelectedProject.Leader.Email}

Items: UsuáriosdoOffice365.SearchUser({searchTerm:cbx_project_leader.SearchText})

ItemDisplayText: ThisItem.Mail

How does the app automatically select a person's email address in this modern combobox?

Hello @nok,

Issue is happening because DefaultSelectedItems must receive the same record/Scheme structure as the ComboBox Items property returns.

Try below code in DefaultSelectedItems of the control:

LookUp( UsuáriosdoOffice365.SearchUser({ searchTerm: varSelectedProject.Leader.Email }), Mail = varSelectedProject.Leader.Email)

works because the ComboBox expects the exact same schema as returned from Item.

Hello nok ,

DefaultSelectedItems expects a table, even for single select comboboxes.
Wrapping the record in [] creates a single-row table.
The returned record from UserProfileV2() matches the schema expected by the ComboBox Items source.

DefaultSelectedItems:
[
Office365Users.UserProfileV2(varSelectedProject.Leader.Email)
]

or

{
Mail: varSelectedProject.Leader.Email,
DisplayName: varSelectedProject.Leader.DisplayName
}

Items: Office365Users.SearchUser({searchTerm: Self.SearchText})

DisplayFields: ["DisplayName"]

SearchFields: ["DisplayName","Mail"]

That will auto-select the existing SharePoint Person value correctly.
