Hello Lovsten,
We have provided a property the purpose of which is to change the size of the drop down, namely the
CalendarSize property.
You could use the following code snippet as an example how to change the size of the drop down:
this.radDateTimePicker1.DateTimePickerElement.CalendarSize = new Size(300, 150);
Please tell me if I could be of your further assistance.
Regards,
Boyko Markov
