calendar control

Hi,
I am using a system.web.ui.webcontrols.calendar, I have a button on my page
that I want to go to today and highlight it. works fine if I am on that
month, but if i switch months... it does not go to today. How can i make
this happen?
with me.calendar1
.selecteddat system.datetime.today
with .selecteddaystyle
.backcolor = drawing.color.blue
.forecolor= draswing.color.yellow
.font.bold = true
end with
.focus()
end with
