I'm successfully printing multiple charts on a single page. What I'd like to add is the ability for the user to selecting a specific chart, and then when they click Print... to have the Print Range groupbox in the dialog that appears from the pm.ShowDialog() have both 'All' and 'Selection' enabled so the user can decide whether to print just the selected chart, or all charts.

Is there a way to affect the enabling of the groupbox and its radiobuttons?

Thanks,
Lee
