Let me make this clear, "Allow refresh on update" option is totally different. This is used to refresh the whole grid when some change happens during the row editing. This is also available for modal edit mode.
Thank you all for your replies, they are much appreciated :)
My exact requirement is whenever the value (of a row) generated by the RD changes - from a webservice, not from row editing- then I would like to refersh my grid, or row holding that value that was changed elsewhere.
As the requirement says to refresh the Data Page every time whenever a record is updated in the DB table and thus in RD. So, what configuration in Data Page will help us achieve this? Do we any option other than "Reload Once Per Interaction" as it would be a performance hit?
MarianeA - Do we have any particular condition / situation under which the data would be updated in RD?
