Pass multiple values from JavaScript to Server Side using doPostBack and EventArgument in ASP.Net

Hi,

I pass a parameter from c# to jquery and receive it back at post back step as follows:

C#:

row.Attributes.Add("onClick", "return func(" + msg.Id + ");");

jquery:

    function func(recId) {
        __doPostBack('DivClicked', recId);
    }

Page_Laod:

            if (Page.IsPostBack)
            {
                string target = Request["__EVENTTARGET"];
                if (target == "DivClicked")
                {
                    string id = Request["__EVENTARGUMENT"];
                    Response.Redirect("MyPage.aspx?senderId=" + id);
                }
            }

How can i pass and receive multiple parameters using the above way?

Thanks.
