RadDateTimePicker not behaving as expected after modify its default style

After extracting the default style for RadDateTimePicker to the resource file to my application (as mentioned in the above page.), RadDateTimePicker is not working as expected.

For current month it picks up the correct date that is selected in the calendar. But for previous months and next months, it is picking up different date than selected.

telerik version- R1 2020

Hello Aanchal,

Thank you for the shared picture.

Have you extracted the ControlTemplate from Visual Studio or from the theme XAML File? Sometimes the extraction through Visual Studio fails and grabbing the ControlTemplate from the xaml file is safer. 

I am attaching a sample project, where I have extracted the ControlTemplate for the RadDateTimePicker for the Fluent theme. Please, check out the shared project, give the above mentioned suggestion a try and let me know how it goes.

Hi,

I am able to use fluent theme in my application but in my telerik folder, I don't have a folder for fluent theme. Can you suggest what I need to do to get it?

Hello Aanchal,

Thanks for the shared picture.

It seems that you are using a UI for WPF version from 2017, however the Fluent theme was introduced in the R1 2018 release. If you want to use that theme, you can upgrade to the R1 2018 version or to the latest one. Note, that we generally recommend using the latest version as it contains the most features/bug fixes. 

I hope you find this information helpful.
