To handle selection changed event - subscribe to
the DatePicker SelectionChanged event as shown in below example
code.
datepicker.SelectedDateChanged = CalendarSelectedDateChanged;
private void CalendarSelectedDateChanged(object sender, SelectionChangedEventArgs e)
{
DateTime selectedDate = datepicker.SelectedDate.Value.Date;
}
Changing
the DateTime format:
Date
picker control doesn’t provide us any direct properties with which we can
change the date format. Alternatively, we can change format of the local
culture by setting the DateTimeFormat
for the current culture to apply it throughout the application. Sample code is
shown below to set ShortDate format to “dd/MM/yyyy”.
private void Application_Startup(object sender, StartupEventArgs e)
{
this.RootVisual = new CalendarControl();
Thread.CurrentThread.CurrentCulture = (CultureInfo)Thread.CurrentThread.CurrentCulture.Clone();
Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortDatePattern = "dd/MM/yy";
}
Happy developing...
