Time Picker User Control
The easiest way to create a WPF TimePicker control is to make a user control wrapped for TimeSpan CLR object. Here is a very simple sample which does that. Basically TimeControl is having 4 DPs one for the entire Value (Which is a TimeSpan) and individual Hours, Minutes and Seconds. (We can optionally add Days and Milliseconds also to make the control rich). Here is a C# class TimeControl.xaml.cs public partial class TimeControl : UserControl { public TimeControl() { InitializeComponent(); } public TimeSpan Value { get { return ( TimeSpan )GetValue(ValueProperty); } set { SetValue(ValueProperty, value ); } } public static readonly DependencyProperty ValueProperty = DependencyProperty .Register( "Value" , typeof ( TimeSpan ), typeof ( TimeControl ), new UIPropertyMetadata ( DateTime .Now.TimeOfDay, new PropertyChangedCallback (OnValueChanged)));
