Is it possible to prevent user to use refresh/reload page?

You can not prevent the user from pressing F5/reloading the page.

Is it possible to prevent user to use refresh/reload page?

"What" are you trying to prevent?

 

[nevaljar]

I need to warn user if he/she is going to leave page without saving. Usually I have used js script in beforeunload like this (https://www.codespeedy.com/alert-before-leaving-page-javascript/).

I tried putting a MsgBox2 in several places within the page to prevent a full refresh (use cache) but can't accomplish it.

This is the order of events when refresh of browser is selected...
