Hi ,
Well you can use ViewState

C#

Viewstate.Add( "MyViewState", "test" );

C#

if( Viewstate["MyViewState"]!=null)
{
   string MyData =  Viewstate["MyViewState"].ToString();
}

Try enabling ViewState property of your controls or otherwise before postback of your page save the page data in Session or ViewState and rebind your controls in IsPostBack of your Page_Load function.
