Ignition Perspective Named Query with WHERE IN Clause

This is really a question on a different topic unrelated to this thread. However …
I think you are asking how to bind a multi-select dropdown ‘value’ to a session variable.

  1. In the Project Browser, select Perspective.
  2. In the Perspective Property Editor | Session Custom, add a new custom property of type Array. Call it ddSelection or whatever.
  3. On your view, select the dropdown and in the Perspective Property Editor add a property binding on props.value to session.custom.ddSelection and make it bidirectional.

For debugging purposes add a label to the view, bind it to the session variable, turn on preview and you should see a list of selected values or [] when nothing is selected.
