All sorts of other properties are available. For example, DateTextBoxes can be configured for earliest and latest possible dates, including invalid dates in this region. In fact, the entire dropdown calendar can be customized with a custom calendar complete with custom developer specified entries and invalid dates.
Validation is another strongpoint in this control (and the package as a whole). Validators are provided to ensure such simple things as proper date formatting and validity (based on a developer defined list), and also more advanced validators which compare dates, check the range they fall in, and ensure that a date does not precede or exceed minimum and maximum dates (defined by the developer).
The calendar which drops down from the DateTextBox is also available in standalone format. In this form, the calendar is even more powerful than when it’s hooked into the DateTextBox.
