When: RadDateTimePicker1.Format = DateTimePickerFormat.Custom RadDateTimePicker1.CustomFormat = "hh:mm tt" and you delete the value (with delete key), then you can not set the time back to 12:00 AM by using arrow keys.
When RadDateTimePicker value is set to null then you are not able to enter in the control, a date which is less than the NullValue date.
Extend the functionality of the RadMaskedEditBox to support continuous user input, i.e. no navigation keys are required to move the cursor between the separate editable parts of the current mask.
Wrong formatted date time when the Custom format is set to ddMMyyyy.
