CalendarExtender with Minimum and Maximum Date that can be selected???

I have Textbox with CalendarExtender and RangeValidator for it..But I need that Minimum value for RangeValidator to be selected is Today(DateTime.Now) and Maximum value to be 1/01/2009 .How to do it,can someone write code for it...I tried but I always get some errors..ControlExtender Format is set to this ="d/MM/yyyy"

Page Load

rangevalidator1.minimumvalue = DateTime.Now.ToShortDateString

rangevalidator1.maximumvalue = "1/01/2009"

Here is the answer...and it works perfectly...

Code behing

ProtectedSub Page_Load(ByVal senderAsObject,ByVal eAs System.EventArgs)HandlesMe.Load

RangeValidator1.MinimumValue = DateTime.Now.ToString("dd-MM-yyyy")

RangeValidator1.MaximumValue ="30-12-2200"

EndSub
