Hi Khasim,

View state is nothing but a hidden field in the page . If you right click and go to page source you will see the encrypted View State data. If you store something like a data table which contains numerous rows it will cause huge performance issue . It is better to use Session .

http://www.codeproject.com/Articles/32545/Exploring-Session-in-ASP-Net

You can save huge datasets within the session .
//Storing dataset on Session
Session["DataSet"] = _objDataSet;
//Check weather session variable null or not
if (Session["DataSet"] != null)
{
//Retrieving UserName from Session
DataSet _MyDs = (DataSet)Session["DataSet"];
}

Thanks,
Priyan

View State stores page value at the time of post back (Sending and Receiving information from Server) of your page. View State use Hidden field to store its information in a encoding format.

Khasim you can store hundred members of information in your view state in OBJECT format like class type or Collection or Array.

Step-(01): Create a class type or collection or array.

Step-(02): Store your all values in that type

Step-(03): Store that type to view state.

Step-(04): Retrieve your information from view state when you need.

Example:-
//Create a simple class and make it as Serializable
[Serializable]
public class student
{
      public int Roll;
      public string Name;
      public void AddStudent(int intRoll,int strName)
      {
            this.Roll=intRoll;
            this.Name=strName;
      }
}

//Store Student Class in View State
student _objStudent = new student();
_objStudent.AddStudent(2, "Abhijit");
ViewState["StudentObject"] = _objStudent;

//Retrieve Student information view state
student _objStudent;
_objStudent = (student)ViewState["StudentObject"];

Hi,
Storing a DataSet inside of the ViewState is a bad practice. If the DataSet will hold hundred of records the ViewState will become very big and you'll get a panelty of performance in the browser page load.
You can save the data in the Session instead or reload it whenever neccesery.
