But one question:
I’m using the TimePicker in my MVVM application but I have the same problems written in comment 13 and 15. Is there a solution to solve the problems? My TimeSpan Property “SelectedTime” in my ViewModel never get changed and the TimePicker always show the current time.

Uses this:

Public Class Format2NumberConverter
Implements IValueConverter

Public Function Convert(ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.Convert
Try
If IsNumeric(value) Then
Return String.Format(“{0:00}”, value)
Else
Return value
End If
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
Return Nothing
End Function

Public Function ConvertBack(ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.ConvertBack
If value.ToString().Length = 0 Then
Return 0
Else
Return CInt(value)
End If
Throw New System.NotImplementedException()
End Function
End Class

///
/// Backing store for the Corner Radius minsutes
///
public static readonly DependencyProperty CornerRadiusProperty =
DependencyProperty.Register(“CornerRadius”, typeof(CornerRadius), typeof(TimePicker),
new UIPropertyMetadata( new CornerRadius(5, 5, 5, 5),
delegate(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
TimePicker timePicker = (TimePicker)sender;
//set the new Corner Radius
timePicker.CornerRadius = (CornerRadius)e.NewValue;
}));

TimePicker.xaml:
Change line 14
CornerRadius=”5″
to
CornerRadius=”{TemplateBinding BorderBrush}”

Thats it. The changes appear to work here ok with the limited testing that I’ve done.

Thanks for the great controls.
