Hi,

I'm&nbsp;looking&nbsp;for&nbsp;something&nbsp;like&nbsp;the&nbsp;Overlay.Drawn&nbsp;and&nbsp;the&nbsp;Overlay.Drawing&nbsp;event&nbsp;in&nbsp;the&nbsp;SL&nbsp;version&nbsp;of&nbsp;MapSuite.

Actually,&nbsp;I&nbsp;would&nbsp;like&nbsp;to&nbsp;start&nbsp;a&nbsp;progressbar&nbsp;when&nbsp;the&nbsp;drawing&nbsp;of&nbsp;the&nbsp;background&nbsp;in&nbsp;my&nbsp;MapControl&nbsp;begins,&nbsp;and&nbsp;stop&nbsp;it&nbsp;when&nbsp;the&nbsp;rawing&nbsp;stops.

Do&nbsp;those&nbsp;events&nbsp;exists&nbsp;?&nbsp;Or&nbsp;is&nbsp;there&nbsp;another&nbsp;way&nbsp;to&nbsp;do&nbsp;that&nbsp;?

Thanks,  
  
Guillaume.
