Refresh only one region instead of the whole page in oracle apex

Question

I have made a region containing 2 display only items and a button.

The button performs some dynamic action (execute pl/sql query) and the page is refreshed every time the button is pressed (submit page action) .

Is there any way that on click of the button only that particular region gets refreshed instead of the whole page?

Also for the display only items, lets say

item_label ==> item_display_value

how to add this (==>) symbol in between?

Answer 1

If the page is submitted, then it will refresh completely - that is how apex works. But if a submit is not needed, you can add an action of "refresh" to the dynamic action and remove the submit. Make sure the "Behaviour > Action" property of the button is set to "Defined by dynamic action". Note that not all region types support refresh, but all report types do.
