Add a new data source to a form

Often, the information that is stored in existing tables doesn't satisfy customer requirements. Therefore, additional tables must be created, and data from those tables must be shown on pages.

You can add new data sources to existing forms through extension. Follow these steps.

  1. In the extension model, create a form extension for the selected form.
  2. Right-click the form extension, and then select New Data Source.
