The TimePicker exposed a property that would alow the user to change the icon of the picker. It was used in the example and the toggle button had that customized arrow. The template of the TimePicker looks like the one of the DatePicker and the Editable ComboBox. They don't have such property. Since you can pretty easily edit the template of all of them in Blend and customize the icon, we decided to remove that property. As you can see in our new demo site the example no more supports it even in Windows7:
The property is about to be marked as obsolete. The change will be done both in WPF and Silverlight, but we have not released the new WPF demo site to the public yet.
If you want a custom template for RadTimePicker we are willing to provide one for you based on your very own custom design (i. e. send us design image).
