SharePoint Choice and Lookup Fields that allow multiple values

[CodyGros]

I'm creating a PowerApps solution that interacts with data from various SharePoint 2016 On-Prem lists. On my main list, I have the following two fields:

1.  State - Lookup field to the States list and allows multiple values to be selected.

2.  ProjectType - Choice field that allows multiple values to be selected.

In my PowerApps solution, I have a gallery configured with my main list as its datasource. I have labels on the gallery to display fields from the items. I'm able to display field values using the following format:

ThisItem.<Field Name>

Example: ThisItem.Title

For the lookup field, I have the following:

ThisItem.State.Value

It does not display any data and the list items have values for the state field.

For the choice field, it is not recognizing the following:

ThisItem.ProjectType

If I add the above in the text property of the label, it shows an error that says "Name isn't valid". 

Anyone experience a similiar issue with lookup and choice fields that allow multiple values or am I doing something incorrectly? Any help is much appreciated.

Hi @CodyGros,

I think there is something wrong with the formula that you provided.

If you have enabled "Allow multiple selections" for the State column and ProjectType column in your SP list, within your app, the ThisItem.State.Value formula and the ThisItem.ProjectType formula would return a Table value rather than a Text value, but the Text property of the Label control is required to provide a Text value.

If you want to display the Table value (multiple values) within a Label control of your Gallery, I think the Concat function could achieve your needs. I have made a test on my side, please take a try with the following workaround:

Set the Text property of the Label control to following formula:

Concat(ThisItem.ProjectType, Value&" & ")

Or

Concat(ThisItem.State, Value&" & ")

More details about the Concat function, please check the following article:

In addition, you could also consider take a try to use a Listbox control to display LookUp column values instead of Label control within your Gallery. The screenshot as below:

Best regards,

Thanks for the reply @v-xida-msft.

I belive the issue is occuring because of SharePoint 2016 On-Prem. 

What is odd is that it recognizes the State field but ProjectType does not even show up as an option:

I have tested this scenario in our SharePoint Online tenant and everything works as expected. This problem seems to only occur when connecting to an on-prem SharePoint list with lookup and choice fields that allow multiple selections.  I was wondering if anyone has experienced this before with on-prem environment  and this is a known limitiation or if I was doing something incorrectly.

If you have multiselect dropdown values and you want to have conditional visibility you can use the following condition in visible property of that Card or whatever,

If(CountIf(DataCardValue.SelectedItems,Value="Selection Required")>0,true,false)
