How to organize silverlight application

Hi all,

I'm doing a silverlight application. In my application i have many Menu items to be handled. So i'm handling each page(item) as an UserControl and using that instance in page.xaml. Here i'm handling all the events in every UserControl in page.xaml.cs itself, so that i need not worry data traversal from page to page. But in my application my page.xaml.cs looks very clumsy. What impact on performance? Will that hav any issues and any other way to avoid that.

Thanks & Regards,

Kishore Vemuri.
