 TextView txtgevalue; 
 string txtvalues; 
 protected override void OnCreate(Bundle savedInstanceState) 
 { 
 base.OnCreate(savedInstanceState); 
 SetContentView(Resource.Layout.Secondpage); 
 txtvalues = Intent.GetStringExtra("DATA_PASS"); //Get The Value 
 btngetvalue = FindViewById < Button > (Resource.Id.btngetvalue); 
 txtgevalue = FindViewById < TextView > (Resource.Id.txtgetvalue); 
 btngetvalue.Click += Btngetvalue_Click;; 
 } 
 private void Btngetvalue_Click(object sender, EventArgs e)
