Hello,
I have a simple form consisting of :
- raddatetimepicker
- checkbox
I want to validate raddatetimepicker to see whether or not the user enters the date& time when the checkbox control is checked.
If the checkbox is unchecked, no validation is occurred.
You could use the CustomValidator control to validate in this case. Access the CheckBox and RadDateTimePicker from the ClientValidationFunction and check for whether user had entered something.
