Hi Ralph,
1) To access the
checkBox in the
DateTimePicker you should do the following:
RadCheckBoxElement checkBox = this.radDateTimePicker1.DateTimePickerElement.Children[1].Children[0] as RadCheckBoxElement;
2) It is not normal behavior and the
checkBox should be unchecked, so this is a bug, which we will fix soon.
If you have any other questions please write me back. We have updated your Telerik points as well.
