Hi Scott,

As for the control name get changed issue you mentioned, it is actually due
to the ASP.NET's NamingContainer which will mangle the actual ID of any sub
controls inside it. ContentPlaceHolder is such a NamingContainer so that it
will mangle the ID of sub controls in it(so as to avoid ID conflicting).

In ASP.NET, you can use the "ClientID" of control to get the identity that
will render at client-side. You can embed it in to your script.
