Hi,

This is my first time using a lookup column type. I have added them to my existing list and it reference another list for a selection of data. I have added it on my app inside the form control. But when i am in New form mode. i don't see the data being listed on the drop down. Works fine within Sharepoint. It does have this formula below on the items section. What can i do to make it work and show the data same as sharepoint?

Filter('Listed Items', Title = "Arms")

Hi @powerdevkris ,

SharePoint Lookup columns are generally not necessary in Power Apps and will cause you a lot of unwanted restrictions and complexity, particularly if you start changing the Items on the Combo Box. Normally the Items would be (if you want to reference the lookup column values)

Choices(YourSPListName.YourLookupColumnName)

The easiest way (without the lookup column) is to simply reference the other list directly

SecondListName.LookupUpFieldName

and then write back to a Text field.

Thanks @WarrenBelz the second one works for me. I can see my list of data.

How can i still make it work to show the data from my list when i select a record in the gallery? The default = parent.default is not working using this approach.

Hi @powerdevkris ,

Probably why I mentioned the alternative (change it to a Text field), however if you need to use the Lookup field, there are two things you need to change (using the "looked up" field and the Lookup field names)

DefaultSelectedItems

{SecondListField: ThisItem.LookupFieldName.Value}

Data Card Update

{ Value: ComboBoxName.Selected.SecondListField, Id: LookUp( SecondList, SecondListField = ComboBoxName.Selected.SecondListField ).ID }
