Get ViewState in a .VB class file

You can try to inherit the page class in your separate class file.

Public Class Separate
       Inherits System.Web.UI.Page

End Class

You can then access ViewState within your class.

I hope this helps.

You can store a viewstate in  your class variable, and then use it when you need.
This example initialize viewstate in constructor:

      public class MyClass
      {
            protected System.Web.UI.StateBag _viewstate;
            public MyClass(System.Web.UI.StateBag viewstate)
            {
                  _viewstate = viewstate;
            }

            public void DoSomething()
            {
                  string s=(string)_viewstate["key"];
            }
      }

You can split the points if you want.  It can be done in here.  It is up to you.  Goodluck with your projects. :-)
