I'd recommend you get a book on MVC or go through some on-line tutorials as you're not really using MVC features that are designed to make this type of code easier. You should use model binding rather than Request.Form.

Since you're not using any model binding by the looks of it, try this:

C#

public ActionResult Index2( FormCollection o){
   ViewData["s1"] = o["My"]; 
   ViewData["s2"] = o["My2"]; 
   return View("View2");
}

Hello ,

The process you are following is wrong here. You must use the HTML helpers like the

C#

@Html.BeginForm Or Ajax in order to bind your model.

Please check the below link to get a better understanding on the model pass between view and Controller.
Html.BeginForm() vs Ajax.BeginForm() in MVC[^]
For pass of data between Controller and view you can use, ViewData, ViewBag Or TempData

Hope this helps,
Thanks

Hello,

I think you have just started your MVC development , I assume that you are curious about how MVC works .

Steps to solve your problem :-
1. Kindly decorate your Index2 Action with HttpPost attribute .

Note :-
1. Attach Debugger to see what all are the request which are send as request object .
2. Pls see that you dont have masterpage or any other page ,which has same Dom Element with same name u you have used for two input box.(My,My2).
3. Use Request.Params["My"] and check.

Although this is not best approch but for learning and experimenting MVC this is fine .
but in real time project go with MVC Model binders concept.
