  View state is applicable only for a page, if you want to trasnfer data to another page then use some other technique like query string or store values on the server.

  But,  Cross Page Posting orServer.transfer is used to redirect the user to other page then ViewState can be accessed across pages.

  I don't know if ViewState is applicable in WebMatrix.

  Anyway "The ViewState object is useful for storing objects between postbacks to the same page. It cannot be used for passing values to other pages."

  At the same link where I have taken this citation, they explain a lot of methods for passing data between web pages: Data Passing Round-Up

  Hi

  I really agree with nijhawan.sau....This is only possible if Cross Page Posting or Server.transfer is used to redirect the user to other page.

  And here is some details.

  ViewStateContainer.aspx.cs
  public partial class ViewStateContainer : System.Web.UI.Page
  {
      protected void Page_Load(object sender, EventArgs e)
      {
          ViewState["Page1"] = "Page1 ViewState";
          Server.Transfer("AccessViewState.aspx");
      }
  
      public StateBag ReturnViewState()
      {
          return ViewState;
      }
  }
  
  AccessViewState.aspx.cs
  public partial class AccessViewState : System.Web.UI.Page
  {
      private StateBag PreviousPageViewState
      {
          get
          {
              StateBag returnValue = null;
              if (PreviousPage != null)
              {
                  Object objPreviousPage = (Object)PreviousPage;
                  MethodInfo objMethod = objPreviousPage.GetType().GetMethod
  						("ReturnViewState");
                  return (StateBag)objMethod.Invoke(objPreviousPage, null);
              }
              return returnValue;
          }
      }
  
      protected void Page_Load(object sender, EventArgs e)
      {
          if (PreviousPage != null)
          {
              if (PreviousPageViewState != null)
              {
                  Label1.Text = PreviousPageViewState["Page1"].ToString();
              }
          }
      }
  }

  Hope it helpful.
