Refresh Grid when Table change with no buttons

I have a Scriptcase Grid Application that shows values from hardware controllers/sensors which send their information directly to MySql tables over the internet.
There are some posts about using a button to refresh grid that could be a solution.
Although, I’m looking for a way to refresh data only when table size increase.
Is there a way to implement a timer to check table size periodically and then refresh if size changes?

Yeah, please read on XMLHttpRequest. It’s not that hard as it looks.

Thank you, I’ll try to figure out how to use XMLHttpRequest for grid refresh
