DataGrid operations using client side C# script ?

Question

Hi, I want to make certain columns visible and certain others invisible depending on radio button the user clicks on - currently I am doing a postback to the server, but that's very slow because the DataGrid re-constructs and Bind()'s and sends the entire thing back to the client side. Can some one suggest a faster way of doing the same thing using client side script ? Also, can sorting be done by any client side scripting ? Awaiting a response, Thanks, -Apurva.
