Question 1

I am using enterprise library 3.1. I have an aspx page which is calling the
business component writen as a WCF data contract. I am using
ajaxControlToolkit.
I have 2 date picker controls..departure and arrival. I want to set the
Validation block so that the arrival date is not less than departure date. I
have Origin and Destination as two seperate properties in my WCF component.
Can some one show me the code...

Question2

I have to do the string validation for one of my text box using enterprise
library validation block. NotNullValidator is not fired as the text retured
is empty. How to check for empty text using validation block.

thanks in advance
