0	There is hardly any reason of getting runtime error if you have the reference of the namespace kept properly on the page. ConfigurationManager class needs System.Configuration namespace referenced into your project and added into the using statement at the top of the class. Just try these in case you have not done already and it should. After trying above, still if doesn't work, copy-paste the complete error you are getting and we shall try to sort it out.
