Question

I’m following this tutorial:

http://www.asp.net/mvc/tutorials/getting-started-with-aspnet-mvc3/cs/examining-the-edit-methods-and-edit-view

It describes a situation when a user click a button and then a function without an attribute is called.

But when a function with HttpPost attribute is added, this function is called and not the function without the attribute.

The button initiates Html.BeginForm() which creates a post request. So why did the function without the attribute got called?

Answer 1

A submit button will ALWAYS initiate a HttpPost request.

A hyperlink on the other hand (a tag), that points to an action will ALWAYS be a HttpGet.

EDIT: I realise your confusion, see below to demonstrate what @RickAndMSFT is trying to say:

Given that we have the following action method:

[HttpGet]
public ActionResult SearchIndex()
{
}

This action will ONLY accept HttpGet requests

NOTE: If we take away the HttpGet attribute, it will accept ALL Request Types.

Therefore, if you have:

public ActionResult SearchIndex()
{
}

There is no need for a post method because the method above already accepts post requests. This is the case because the page in question isn’t actually modifying/saving/creating anything, it’s just listing data.
