The date or month or year field in dropdown can be customized by this event.

Examples
<editors:SfDatePicker DateFieldPrepared="OnDateFieldPrepared"
                      HorizontalAlignment="Center"
                      VerticalAlignment="Center">
</editors:SfDatePicker>
private void OnDateFieldPrepared(object sender, Syncfusion.UI.Xaml.Editors.DateTimeFieldPreparedEventArgs e)
{
   if (e.Column != null && e.Column.Field == Syncfusion.UI.Xaml.Editors.DateTimeField.Day)
   {
       e.Column.Format = "ddd dd";
   }
}

SelectedDateChanged

Occurs when the SelectedDate value is changed.

Declaration
public event EventHandler<SelectedDateTimeChangedEventArgs> SelectedDateChanged
Event Type
Type Description
System.EventHandler<SelectedDateTimeChangedEventArgs>

When editing date as input, DateFieldItemPrepared will not be triggered, hence it is not possible to decide that the given input is a blackout date or not. However, once editing is completed, SelectedDateChanging event will be triggered. Here we can cancel the date from selection, if it is a blackout date.
