Jquery how to pass GridView as a parameter to a WebMethod

Hello,

I'm trying to pass a GridView as parameter from Javascript to a WebMethod. Here's my code:

"http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type="text/javascript">
"text/javascript">
function bindGrid() {
var pageurl = '<%=ResolveUrl("Default.aspx/bindGrid1") %>';
var gv = $("#<%=gvDisplay.ClientID%>").val();
var idno = $("#<%=txtIDNO.ClientID%>").val();
var name = $("#<%=txtName.ClientID%>").val();
var tel = $("#<%=txtTel.ClientID%>").val();
var parameter={"gv":gv, "idno":idno,"name":name,"tel":tel}
$.ajax({
type: "POST",
url: pageurl,
data: JSON.stringify(parameter),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: OnSuccess,
failure: function(response) {
alert(response.d);
}
});
}
function OnSuccess(response) {
alert(response.d);
}

and the WebMethod:

[WebMethod]
public static string bindGrid1(GridView gv, String idno, String name, String tel)
{
string message = "";
DataSet ds;
SqlDataAdapter SqlAda;
SqlConnection con = getConnection();
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "sproc";
cmd.Parameters.Add("@IDNO", SqlDbType.VarChar).Value = idno;
cmd.Parameters.Add("@Name", SqlDbType.VarChar).Value = name;
cmd.Parameters.Add("@Tel", SqlDbType.VarChar).Value = tel;
cmd.Connection = con;
try
{
con.Open();
gv.EmptyDataText = "No data.";
SqlAda = new SqlDataAdapter(cmd);
ds = new DataSet();
SqlAda.Fill(ds);
gv.DataSource = ds;
gv.DataBind();
message = "success";
}
catch (Exception ex)
{
appObj.myMessageBox(ex.Message);
message = "error";
}
finally
{
con.Close();
con.Dispose();
}
return message;
}

I know I can't pass it as a string, but I can't find a way to pass it.

Any kind of help would be appreciated.

Thank you in advance.

Honestly, I will be dead surprised if you could managed to do something like this. Let me first declare that I am not quite an expert on the subject, but still commenting to best of my ability.
I think GridView is your server side control. So if you want to bind it it's object reference will be required. You cannot pass object references in Ajax calls.
I believe you should be doing all this server side itself. May be post a page.
