How to pass data from asxp page to silverlight

Question

Hi. 

I am already having an application in asp.net 4.0 now.I want to use silverlight control instead of asp.net control, for this I have send data from aspx.cs to xaml.cs so that i can bind my Silverlight control with the data so suggest me  how to send data from aspx to xaml...and xaml to aspx page. My WCF service return Dataset to aspx page. I want to get data on XamL  without using Entity framework as well as Linq to SqL.

Any help or suggestion will be appreciated
