>>The next one I am trying to do is enabling a "Continue" button when all three of the userID, Password, and retype password textboxs have been filled out or validated client side. Basically I do not want them to continue until I have valid values in all three boxes and the two passwords match. How would you approach this? I am adding jQuery into this project now.

If you want to display an error message (to let them know their passwords don't match) then you'll want to add something like a div section with the message and hide or show it selectively. Something like this:

Thanks a bunch Paul, this is helpful.. I also found this Validation plug in for jquery that is really nice.
http://docs.jquery.com/Plugins/Validation
Problem is I cannot figure out how to get a script or a script source into my page from the user control. I tried a RadCodeBlock and thought that was supposed to work but it does not. I also tried this in the OnInit

Page.ClientScript.RegisterClientScriptResource(GetType(), "~/scripts/EnrollmentValidation.js");

Since I am using Telerik, there is a RadScriptManager on the outside Master page but it doesn't appear I can register a script with the script manager since it is in the master.
