How to determine if the view is for GET or POST in ASP.NET MVC?

MVC use action attributes to map the same view for http get or post:

 [HttpGet] 
 public ActionResult Index()
 {
    ViewBag.Message = "Message";
    return View();
 }

 [HttpPost]
 public ActionResult Index(decimal a, decimal b, string operation)
 {
     ViewBag.Message = "Calculation Result:";
     ViewBag.Result = Calculation.Execute(a, b, operation);
     return View();
 }

In the MVC view, how can I determine if the view is for http get or http post?

in Views it is IsPost

@{
     var Message="";
     if(IsPost)
      {
            Message ="This is from the postback";
      }
       else
    {
            Message="This is without postback";
    }
}

PS: For dot net core it is:

Context.Request.Method == "POST"

When checking for "postback" in ASP.NET CORE 7, you should also check if the model is valid like so:

    if(ViewData.ModelState.IsValid && Context.Request.Method == "POST")
    {
        <p><strong>Yes I am Postback and Valid!</strong></p>
    }

<% if (System.Web.HttpContext.Current.Request.HttpMethod.ToString() == "GET") { %><!-- This is GET --><% }
   else if (System.Web.HttpContext.Current.Request.HttpMethod.ToString() == "POST")
      { %><!--This is POST--><%}
      else
      { %><!--Something another --><% } %

System.Web.HttpContext.Current.Request.HttpMethod stores current method. Or just Request.HttpMethod inside of view, but if you need to check this, there may be something wrong with your approach.

Think about using Post-Redirect-Get pattern to form reposting.
