Hello Parthiban,

May I ask if it would be possible to give the following article from our documentation a try? It showcases how to set a different culture and modify the display pattern: 

WPF DateTimePicker - How to set different culture - Telerik UI for WPF

But how to archive the in XAML.

Just I want to display the format 1JUL2025

Hello Parthiban,

The properties of the DateTimeFormatInfo class cannot be set directly in XAML. Instead, this customization will have to be done in code.

What I could suggest would be to implement an attached property of the type of string, which you can set in XAML to the desired pattern, and apply it in its property callback method.
