Populating a list box with the fields of a File Browse tool selection

In the previous recipe, we created an Analytic App that allows users to select which fields they want to use to create summarizations.

In this recipe, we’ll add a little more interactivity to the same app so that users can select the input file to create the summarizations.

The summarization fields will remain the same (Visits and Spend) and must be present in the file.

Getting ready

• The resulting app from the fourth recipe:

• The UI of the app:

We will add a feature to select what data source...
