Radgrid flash on refresh / rebind

I have a RadGrid linked to a datasource that acts as a live dashboard.  On a timer, asp:Timer, I rebind the grid to retrieve the new data values and update the RadGrid.  Doing this causes the RadGrid to refresh and for a moment the page flashes.  Functionally everything works fine, but this flash is distracting to the user.

What can I do to remove this flash?  Are there any double-buffering type techniques I can use?  To force an update of the RadGrid do I have to rebind or is there some other method I can use?

thanks
