How to clear node when I clicked F5 (refresh)?

When I page out , click 'F5' refresh button, close dashboard page , I want to refresh my node

Now, my dashboard page is remained pre-selected values.
//selected dropdown values , selected switch.., clicked button , values after select DB etc...

it need to be cleared when another user paged in my dashboard.

How to I solve it??

You can use a ui-control node. That will send a message every time you open the page, switch tabs, refresh etc. You can use that to clear the data on the tab.

@Colin Can you show some examples???

Have you looked at the help pane for the control node?

Have you dropped one onto a flow and fed the output to a debug node set to show Complete Message? and looked to see what comes out when you refresh the dashboard browser page?
