I like a @sohailby answer but I just want to change little by using blackoutdates 


  <DatePicker.BlackoutDates>
     <CalendarDateRange End="{x:Static sys:DateTime.Today}" Start="{x:Static sys:DateTime.MinValue}" />
  </DatePicker.BlackoutDates>

In WPF and you want to use MVVM binding to your view model. This approach is more general and lets you do boundary checking within your unit tests.

   <DatePicker SelectedDate="{Binding SelectedDate}"  DisplayDateStart="{Binding MinAvailDate}" DisplayDateEnd="{Binding MaxAvailDate}"></DatePicker>

In the view model.... 

private DateTime _minAvailDate= DateTime.UtcNow;
        public DateTime MinAvailDate { get { return _minAvailDate; }
        set { _minAvailDate = value; OnPropertyChanged("MinAvailDate"); }

Set MinAvailDate = DateTime.Now, or adjust the default for your time zone.
Implement MaxAvailDate in a similar way, as well as you binding to the SelectedDate.

You have to set the DisplayDateStart attribute with Today's date

<DatePicker Name="dt_StartDateFrom" DisplayDateStart="{x:Static sys:DateTime.Today}">
</DatePicker>

Make sure you have set the

xmlns:sys="clr-namespace:System;assembly=mscorlib"

in your <UserControl> tag to be able to use the sys: parameter

P.S. To Disable future dates, you can use DisplayDateEnd attribute

This is a neater solution to the problem in case we want to add it through xaml.

To block out the past dates (everything before today), you can simply use the Framework's 4.0+ method : AddDatesInPast()

myCalendar.BlackoutDates.AddDatesInPast();

It does the same as the accepted answer but is more straightforward.

Caldr.DisplayDateStart = DateTime.Today;

I got the solution by trying myself.

In Window_load just add this line for calendar.

Caldate.BlackoutDates.Add(new CalendarDateRange(new DateTime(1990, 1, 1), 
DateTime.Now.AddDays(-1)));

It will block previous dates.

You can set the DisplayDateStart property to today.

myCalendar.DisplayDateStart = DateTime.Today;

Instead of hiding all previous values, if you want to black them out, you can do this.

CalendarDateRange cdr = new CalendarDateRange(DateTime.MinValue, DateTime.Today);
myCalendar.BlackoutDates.Add(cdr);
