Hi Juergen,
Thanks for using syncfusion product.
We request you to provide following details.
1.Update us the type of Autoformat that you are requesting for DateTimePicker.
2. Whether you would like to use custom CSS for DateTimePicker (or) need to apply the same Autoformat to DateTimePicker, which is set to Grid? I.e. AutoFomat of Grid is “Office 2003 Blue”, then same needs to apply to datepicker?
Please explain the details. So that we can analyze based on that also and provide you better solution and let us know if you have any other queries.
Regards
Kavitha N.
