Click the submit button to post the selected value in the DateTimePicker. When posting the null value, validation error message will be shown below the DateTimePicker.
This sample demonstrates the strongly typed extension support in DateTimePicker. Value is set as model object to the DateTimePicker from the code behind, and its set to DateTimePicker in view page by invoking the strongly typed DateTimePickerFor helper with the lamba expression.
More information on the DateTimePicker instantiation can be found in the documentation section.
