     { 
      Text = "Forgot Password?", 
      FontSize = 20, 
      TextColor = Color.Blue, 
      HorizontalOptions = LayoutOptions.Center, 
     }; 


     // Your label tap event 
     var forgetPassword_tap = new TapGestureRecognizer(); 
     forgetPassword_tap.Tapped += (s,e) => 
     { 
      // 
      // Do your work here. 
      // 
     }; 
     forgetPasswordLabel.GestureRecognizers.Add(forgetPassword_tap);
