Hello,

I need to populate a combobox with the currently signed-in user, if the combobox is empty. what's the best way to achieve that?

I've tried - If(IsBlank(ThisItem.'PSS Assignment'),User().FullName

Also, I'll like to retain the ability to search.

PSS Assignment is the combobox name.

Thanks!

@HenryXterra Could you please share the full formula you have in the Items and defaultselecteditems property of the combobox.
Where is the formula that you had share earlier (in which control, in which property)?
what does ThisItem refer to in that formula?

The data source is a SharePoint list, so the combobox is a people picker in SharePoint.
Items: Choices([@'Virtual Lobby'].PSSAssignment)
DefaultSelectedItems: Parent.Default
ThisItem refers to the selected item from a gallery.

Hi @HenryXterra ，

Try to set DefaultSelectedItems property of your combo box to below formula:

If(IsBlank(ThisItem.'PSS Assignment'), { '@odata.type': "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedUser", DisplayName:User().FullName, Claims:"i:0#.f|membership|" & User().Email, Department:"", Email:User().Email, JobTitle:"", Picture:"" }, Parent.Default)

Best regards,

Allen
