ADD. RadCalendar's TodayButton does not accept shortcuts.
There are two ways to add shortcut to the TodayButton 1. You can use mnemonic and set the '&' symbol prior the desired char: radCalendar1.CalendarElement.CalendarStatusElement.TodayButton.Text = "&Today"; 2. You can use RadShortcut: radCalendar1.CalendarElement.CalendarStatusElement.TodayButton.Shortcuts.Add(new RadShortcut(Keys.Control, Keys.B));
