Hello Aymen,

The RadDateTimePicker control internally uses a RadCalendar, which provides functionality for customizing the CalendarButton elements (this element represents each date in the calendar part) that will allow you to achieve the desired behavior:

WPF Calendar - How to Customize the Calendar Buttons - Telerik UI for WPF

Generally, you can follow the approach from the above article and combine it with the API that the RadDateTimePicker control exposes for customizing the RadCalendar element:

WPF DateTimePicker - Styling the Calendar - Telerik UI for WPF

With this being said, I have attached a sample project for you to test, which produces the following result when using the above two articles:

I hope the provided information will be of help to you.
