Create the UIPopulator NetLogic

Create a NetLogic that automatically creates UI elements based on the Model objects properties.
Prerequisites
Set the default external code editor. See Set the default code editor.
  1. To create the UIPopulator NetLogic
  2. In
    Project view
    , right-click
    VerticalLayout1
    and select
    New
    Runtime NetLogic
    .
  3. Hover-over the NetLogic, select
    Edit
    , and enter
    UIPopulator
    .
  4. Double-click the NetLogic.
    The external code editor opens.
  5. In the code editor, replace the existing code with the following code:

  6. Save the code.
