Update Multi Value lookup with Collection

[stephe]

Hi All,

On my app (connected to SharePoint list) there is a lookup field called Customer, however this list is 7000+ items, so users select a Customer via a textinput and a gallery control on another screen. Items control of the Customer field is blank and the Update control of the Customer field is set to:

{Id: LookUp('Customer', Title = CustomerResults.Selected.Title, ID), Value: CustomerResults.Selected.Title}

This works perfectly.

I have the same lookup in another field but this is called Associate Customers and allows multiple lookup values. When the user searches for Customers and selects them from the gallery it populates a collection: SelectedAssociatedCustomers

I can get the items to show in the lookup field via DefaultSelectedItems: SelectedAssociatedCustomers.Value. If i were to submit this it wouldn't update the SharePoint list item, the field would remain blank, therefore, I need to set the Update control but i am unsure the syntax for this?

Please help if possible.

Thanks!

Hi,

Make sure your multi-selection box has these properties (with your defaultSelectedItems in there):

And then your DataCard Update property is set to

SelectedAssociatedCustomersActualFieldBoxName.SelectedItems
