WP7 Trouble customizing DatePicker control

I'm using the DatePicker control fr开发者_如何学编程om the WP7 SL toolkit. It navigates to DatePickerPage.xaml, which has the scrollers for date picking. I want to keep all the functionality, but change the colors. I'm messing around with DatePickerPage.xaml and updating colors to fit my needs.

I've been able to update the text colors on the scrollers and header, but I can't figure out how to update the background color on the selected item in each or the square outline while the scroller is active. Based on tests I have done with changing the background color of the DatePickerPage.xaml, it appears that the selected item and square outlines are an opaque version of the background color. Unfortunately, this wont work for me, since I want the background to the be white and the outlines aren't visible. Is there a way to explicitly set those colors?

If you get the control into Blend and right click on it and select Edit Tempate --> Edit a Copy, you'll get the template for the control so that you can edit it.

What you'll be looking for is the resources keys that are used for the background, foreground, etc. You can replace them with your own resources, or hardcode them, or the best option is to override the resource.

Additional Advice

Be careful though, don't forget that a user can have either a dark or light background to the phone, so unless your app is taking control of the background color of the whole page, you need to consider what might happen when picking colors
