I have a Canvas App that displays data from some SharePoint Lists.

Companies is a list of Companies 🙂

Articles is a list of Articles about those Companies.

An Article can be about one or more Companies.

I do a Lookup from the Articles List to the Companies Lists.

I have two galleries.

Is there a way to show the amount of Articles about a Company in the Companies Gallery?

The Articles and Companies galleries are one two different pages.

Thanks

Yes do a CountRows with a Filter.

Or @pmwhelan You can use a:
CountIf(Articles ,companyLookupId=ThisItem.Id))

You can use something like :
CountIf(Articles ,companyLookupId=ThisItem.Id)).
To avoid delegation you can, use collections and put countRows over collection.

No its not delegable . You can use countif if your data limit is less . If you have to handle more records , go with delegable functions/collection method .

Hi @pmwhelan ,

If your Filter returns less records than your Delegation limit, you can do this

With( { wComp: Filter( Articles, companyLookupId = ThisItem.Id ) }, CountRows(wComp) )
