Need help with linking two sharepoint lists in same gallery

[Anonymous]

Hi everyone,

I have 2 Sharepoint lists, let's say ListA and ListB and they are both connected to my PowerApps canvas app

ListA has fields

ID    Currency

1        EUR

2        USD

3         JPY

4        CNY

ListB has fields

ID     

1

1

1

3

4

I made a gallery consists of ListB items and now I would like ListB to show the Currency matching the IDs in ListA instead of showing the numbers so ideally the gallery will show

EUR

EUR
EUR
JPY
CNY

is this achievable? If not, what are the alternatives? Thank you all in advance 🙂

This should be achieveable with the Lookup function, something like this:

LookUp( ListA, ID = ThisItem.ID, Currency), put this code in the Text property of the gallery label.

However, because both columns are called 'ID' PowerApps may throw a tantrum which means you'll have to use disambiguation or RenameColumns() to fix it. RenameColumns would look like:

LookUp ( RenameColumns(ListA, "ID", "ID1"), ID1= ThisItem.ID, Currency)

This is definitely achievable.  My assumption is ID is a number type column and currency is a text type column.  No lookup type columns are being used in either collection.

The simplest way is to put a label in your gallery with the following code in the Text property.

LookUp(ListA,ThisItem.ID,Currency)

Another way is to put this code in the Items property of your gallery...

DropColumns(
    AddColumns(ListB,"Currency",LookUp(ListA,ThisItem.ID,Currency)),
    "ID"
)

...and then put a label with the following Text property in the gallery

ThisItem.Currency

My preference would be the 1st option.

Thank you guys so much! @mdevaney @Anonymous 

I made it work by combining both of your answers. 

I changed the text field of the label as LookUp(ListA, ID = ThisItem.ID, Currency) and it worked perfectly without name ambiguity problems 🙂

I appreciate your help and have a nice day where ever you are!
