Joining Layers in ArcGISPro

I am joining 2 layers (i.e. attribute tables). I am trying to get all values to show up in both layers in the join. In stead, I get the features that are related and then it nulls out the rest. Am I missing a step in Pro??

No one else has this question

  So, I would be joining 2 layers with the field BridgeID in both tables. The end result I would like them to be joined by Bridge ID and also have all information in the fields showing. Right now, when I join by Bridge ID the joining layer has null’s if there is not a match. I don’t want any nulls. Please let me know if that helps.

    Michelle,
    
    Are you trying to do this with the ArcGIS Pro user interface or with C# code? If you're doing it with C# code, what classes are you trying to use?
    
    Thanks,

      ArcGIS Pro. I was hoping they made the joining tables/layers improved.

        Ah, ok. This is the software development kit forum. I think if I tag ArcGIS Pro they will see it, but you might also try posting it at the Ask ArcGIS Pro section of GeoNet.

        Thank! I couldn’t find the tag for just Pro. I appreciate it.

        Are you able to perform this same join in ArcMap without getting null values if the joining layer does not match?

        I tried in ArcMAP as well. It doesn’t keep the values in the records. I thought there was a way of joining and keeping all information in both tables. I’m thinking I’m wrong.
