MVC which submit button has been pressed

Question

I have two buttons on my MVC form:

<input name="submit" type="submit" id="submit" value="Save" />
<input name="process" type="submit" id="process" value="Process" />

From my Controller action how do I know which one have been pressed?

Answer 1

<input name="submit" type="submit" id="submit" value="Save" />
<input name="process" type="submit" id="process" value="Process" />

And in your controller action:

public ActionResult SomeAction(string submit)
{
    if (!string.IsNullOrEmpty(submit))
    {
        // Save was pressed
    }
    else
    {
        // Process was pressed
    }
}

Answer 2

Can you not find out using Request.Form Collection? If process is clicked the request.form["process"] will not be empty

Answer 3

I suggest looking at this post. I like the second solution since you are programming the logic in the controller and not in the view.

Name both your submit buttons the same

<input name="submit" type="submit" id="submit" value="Save" />
<input name="submit" type="submit" id="process" value="Process" />

Then in your controller get the value of submit. Only the button clicked will pass it's value.

public ActionResult Index(string submit)
        {
            Response.Write(submit);
            return View();
        }

You can of course assess that value to perform different operations with a switch block.

public ActionResult Index(string submit)
        {
            switch (submit)
            {
                case "Save":
                    // Do something
                    break;
                case "Process":
                    // Do something
                    break;
                default:
                    throw new Exception();
                    break;
            }

            return View();
        }
