Refresh Gridview on an update panel ONLY when user is not updating the Gridview

I have an update panel. Inside a gridview with templates for text boxes and drop down lists. There is a trigger that refreshes the grid every 10 seconds.

The goal is to avoid refreshing the gridview if the user is editing any of the text boxes or the drop down lists. How can I do this? I thought about using Javascript to run every 10 seconds to check the if any of the textboxes or dropdownlists have focus. If any of the controls have focus then ignore, else refresh the gridview. Is there a better approach or way to do this?
Thank you,
