Hello Mahipal,

I am just checking if you got this worked out or you still require any assistance or clarification on the matter.

Hi Mahipal.nareddy,

You could change the mask of XamDateTimeEditor by providing its new value like this:

mskDate.Mask = "yyyy/mm/dd";

where mskDate is the instance of the control.

For more information on the Mask property, please take a look at the following article.

If you have more questions on the matter, please feel free to ask.

Best Regards,
Milana Zhileva
