- To open the properties dialog box of a layout or an embedded section in Dev Studio, in the Dynamic layout header, click the View properties icon.

- Optional: To run an additional operation on refresh, perform the following actions:
- To run a data transform, select the Run data transform checkbox, and then provide the name of the data transform.
- To run an activity, select the Run activity checkbox, and then provide the name of the activity.
