Is there any way to tell which property does a value come from?
<p>I know its a long stretch but... just had to try.</p>

<p>For example if I made a DateTime control with a SelectedDate property, if in the server-side code it is being set to Person.DateOfBirth, in the DateTime control is there any way to tell that the SelectedDate came from Person.DateOfBirth?</p>
