asp calendar

http://aspnet.4guysfromrolla.com/demos/simpCal.aspx


i want to modify this calendar that will look like this:
http://zdravstveno.narocanje.si/zn/public/resource/resCalendar.html?date=09.10.2009&id=2&c=1&iom=01.10.2009


but i have problems. How can i make my own events on calendar date clicks and how to change design of it. I read this but it is not helpful:
http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.calendar%28VS.80%29.aspx


Does anyone have any good tutorial?


regards
