Progress Telerik UI for WPF

DateTimePicker

TimePicker

Use the drop-down interface for selecting times using either pre-defined values or custom data sources.
DatePicker

DataPicker provides a drop-down interface for RadCalendar that allows selection of dates, all using a minimum space in your user interface.
Validation Support

The built-in data validation support helps ensure that users are notified if they select dates that work against the business logic of your application.
Combined DateTimePicker

Take advantage of RadDatePicker and RadTimePicker combined into a single UI. That combination allows you to save space in your application without compromising seamless experience of date and time selection that users enjoy.
