Is it possible to filter a gallery based on ID in a SharePoint Lookup column?

[Anonymous]

I have a lookup column in a SharePoint list (List A) and would like to filter the list to show items in a gallery that display the currently selected ID for an item in the second list (List B). Is this possible? Here is a sample:

List A

Item	Text [LOOKUP]
A	2
B	3
C	2

List B

ID	Entry
2	Text.
3	Also text.

I would like my gallery to only show items A and C from List A because they are linked to the item with the ID of 2 in List B. I get a delegation error when I try to filter the gallery by using Text.Id = Selected.ID

Hi @Anonymous ,

Yes Lookups on the ID number is not Delegable.

One workaround is to have another field in PowerApps (hide if if you want to) and make the Default to the ID.

You can then do delegable lookups.

Thanks for the response. What do you mean by field in the app and setting its default?

Hi @dehmos27 ,

Yes - you can hide it on the new form - it will set when a new record is created. There are other ways such as a Patch, but sometimes simple is good. You then have a numeric field the same as the ID, which is delegable for Filters.
