Thank you for contacting us.
Are you using the RadScheduler
or the RadScheduleView
If you use RadScheduler control, attached you will find the whole style of the control. There you will be able to find the PART_DeleteButton
and copy its style to your other button. But you will have to apply the whole style as a custom theme or as a style to the RadScheduler.
Hope this is helpful. If you have any other questions please let us know.
