Hello Hector,

The TextBox is a simple control that renders one single INPUT element, which is the reason that you are able to use the required attribute on it. However, with RadDatePicker and RadComboBox this will not be possible and you have to use RequiredFieldValidator or CustomValidator controls for your validation.

In the following online demo you will find an example for validating RadDatePicker and RadComboBox controls:

Hope this helps.
