I have added some small .NET object wrappers to the client-side JavaScript. As an example I have build a DataSet wrapper that you can use to submit a DataSet to the server using AJAX in the same way you are using DataSets on the server-side .NET code:

<script language="javascript">

var ds = new System.Data.DataSet("MyDataset");
var dt = new System.Data.DataTable("FirstTable");

// create the columns
dt.addColumn("FirstName", "System.String");
dt.addColumn("Alter", "System.Int32");
dt.addColumn("Datum", "System.DateTime");

dt.Rows.push({"FirstName":"Hans Werner","Alter":20,"Datum":new Date()});
dt.Rows.push({"FirstName":"Witzbold","Alter":333,"Datum":new Date(1977,4,20)});

// you can use a "row object", too
var r = new Object();
r.FirstName = "Michael";
r.Alter = 999;
r.Datum = new Date();
dt.Rows.push(r);

ds.Tables.push(dt);    // add the DataTable to the DataSet ds

// add a second table to the DataSet

var dt2 = new System.Data.DataTable("SecondTable");
dt2.addColumn("FamilyName", "System.String");
dt2.Rows.push({"FamilyName":"Schwarz"});
ds.Tables.push(dt2);

// ...and submit the DataSet to the AJAX method

WebApplication1.DemoMethod1(ds);

</script>
