How to use multiple submit buttons in ASP.NET MVC

Question

I use this code in a view:

<button type="submit" name="SB1" value="submit1"><i class="fa fa-save"> Save</button>
<button type="submit" name="SB1" value="submit2"><i class="fa fa-update"> Update</button>

, and this code in a controller:

[HttpPost]
public ActionResult AddUser(string SB1) {
    switch(SB1) {
        case "submit1":
            // my code..
        case "submit2":
            // my code..
    }
}

However, SB1 string is null . also, I want use button not use input tag because I use string and fa icon in button value.

Answer 1

 [HttpPost] public ActionResult AddUser(string SB1) { switch(SB1) { case "submit1": // my code.. case "submit2": // my code.. } return View(); }

 <form method="post" action="@Url.Action('AddUser')"> <button type="submit" name="SB1" value="submit1"><i class="fa fa-save"> Save</button> <button type="submit" name="SB1" value="submit2"><i class="fa fa-update"> Update</button> </form>

By this way, You will get appropriate name of button being click.

Answer 2

make both a type button and on click, you can make ajax call :

<button type="button" name="SB1" onliclick=save()><i class="fa fa-save"> Save</button>
<button type="button" name="SB1" onliclick=update()><i class="fa fa-update"> Update</button>

<script>
    function save() {
        $.ajax({
            //call for first code
        });
    }
    function update() {
        $.ajax({
            //call for second code
        });
    }
</script>

or you can put on button click using jquery like in below URL: https://www.w3schools.com/jquery/ajax_ajax.asp

Answer 3

You can try this

<button type="button" onclick="location.href='@Url.Action("YourAction", "YourController")'"><i class="fa fa-save"></button>

YourAction: AddUser / UpdateUser

Answer 4

Doesn't a POST return either a model or a FormCollection ?

[HttpPost]
public ActionResult AddUser(FormCollection form) 
{
    string SB1 = form.Get("SB1");
    switch(SB1) {
        case "submit1":
            // my code..
        case "submit2":
            // my code..
    }
    return View();
}

<form method="post" action="@Url.Action('AddUser')">
  <button type="submit" name="SB1" value="submit1"><i class="fa fa-save"> Save</button>
  <button type="submit" name="SB1" value="submit2"><i class="fa fa-update"> Update</button>
</form>
