Saving and Retrieving a Dataset to and from View State.

To save:

sqlDataAdapter1.Fill(dSet);
System.IO.StringWriter sw = new System.IO.StringWriter();

// Write the DataSet to the ViewState property.
dSet.WriteXml(sw);
ViewState["dSet"] = sw.ToString();


To retrieve:

if (Page.IsPostBack)
{
System.IO.StringReader sr =
new System.IO.StringReader((string)(ViewState["dSet"]));
dSet.ReadXml(sr);
}


Without saving and retrieving from and to viewstate in asp.net, using dataset becomes inefficient completely. I’ve been seeked these methods to load information database only once if not already loaded and finally got it.
