Hi,
I am working on developing a mobile app containing about 4 fields. The data source is sql table (on prem), connected with gateway connection and added as data source in my app. See screenshot below for the dd control properties.

With this config, it loads all values from field 'personnelfirstname' into the dd. However, I would like to load 'PersonnelFirstName PersonnelLastName' into the dd as concatenated value with space. Can someone help me with the expression to set for items property, this should be simple enough but I am unable to figure it out. Also, once this is configured, I would like to display 'PersonnelID' in a label based on the selection in dd, any help on this would be greatly appreciated, thanks in advance.
