Dropdown OnChange Other Column Value

(0) ShareShare
ReportReport
Posted on by RobDin 71

I've created a dropdown that displays LastName, FirstName from a collection queried from a user table. Within that table I have a GUID that I want to use as an identifier for another query later.

 

DropDown1

Items: Concatenate(UsersCol.LastName,", ",UsersCol.FirstName);

 

How do I construct the OnChange for the dropdown so that it gets the GUID and when I make a selection?

    @RobDin It would be better to use a Combobox and set the Items property to UsersCol, Primary Text to LastName and SecondaryText to FirstName.

    Then to get the GUID,

    First(combobox.SelectedItems).GUIDcolumn

     

    Please remember to give a 👍 and accept my solution as it will help others in the future.

    This worked well after I combined the FirstName and LastName columns into a FullName column on the back end data source.
