问题:

According to this post, there's a separate DatePicker control in .net 4. I've tried it, and I don't see a good way to also let it select the time of the day.

Is there an easy way to transform DatePicker into DateTimePicker by editing XAML template? If not, what is the best way to get a DateTimePicker for WPF 4.0?

回答1:

Extended WPF Toolkit sports a nice DateTimePicker with time of day.

There is also an article over on CP where someone created a control that works like the Winforms one... A WPF DateTimePicker That Works Like the One in Winforms

There isn't one without making it yourself or using a 3rd party control. However there is one within winforms if you want a quick fix that doesn't support data binding...

xmlns:window="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration"
xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"

<window:WindowsFormsHost >
    <wf:DateTimePicker Format="Time" ></wf:DateTimePicker>
</window:WindowsFormsHost>

Just a time picker, but could easily be paired with a datepicker. You also need a reference to WindowsFormsIntegration and System.Windows.Forms.
