What do mean "parent page" is it a Master Page Template or is it frames? Use Improve Question to add some more detail. In any case, I'd suggest using JavaScript on the client side and not use server side code.

Page of what? Is it ASP.NET? Then please add a tag: "ASP.NET". Use "Improve question".

Did you pay attention that I suggested "Improve question"? You are the one the most interested in it, because the tag (like "C#3.5" you already put) should bring your post to the attention of the members competent in C# and ASP.NET even before this Web page is opened...
