  Hello Telerik
  I need to restore (some) default date in InputBox after user has blanked input. I have solved this task by binding SelectedValue-property to an Date object, implementing PropertyChanged event of the INotifyPropertyChanged interface and adding a Handler for LostFocus event. This approach works but I wonder if there is a better and smarter solution(solutions).
  Thanks in advance.
  Best regards\ Olena.

  Hello Olena,
  
  I do not think you need to add handler for the LostFocus event of RadDatePicker. This is how I managed to implement it:

  private DateTime? selectedDate;

   

  public DateTime? SelectedDate

  {

      get

      {

          var value = this.selectedDate == null ? DateTime.Today : (DateTime)this.selectedDate;

          return value;

      }

      set

      {

          var val = value == null ? DateTime.Today : value;

          this.selectedDate = val;

          OnPropertyChanged("SelectedDate");

      }

  }

  
  Hope this helps.

  So the trix is to declare this property as nullable!!! Date.
  Thanks a lot for your assistance, Ivo.
