How do you handle multiple submit buttons in ASP.NET MVC Framework?

Question

Is there some easy way to handle multiple submit buttons from the same form? Example:

<% Html.BeginForm("MyAction", "MyController", FormMethod.Post); %>

<input type="submit" value="Send" />

<input type="submit" value="Cancel" />

<% Html.EndForm(); %>

Any idea how to do this in ASP.NET Framework Beta? All examples I've googled for have single buttons in them.

You can try using this clean attribute-based solution to the multiple submit button this way:

[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)]

public class MultipleButtonAttribute : ActionNameSelectorAttribute

{

    public string Name { get; set; }

    public string Argument { get; set; }

    public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)

    {

        var isValidName = false;

        var keyValue = string.Format("{0}:{1}", Name, Argument);

        var value = controllerContext.Controller.ValueProvider.GetValue(keyValue);

        if (value != null)

        {

            controllerContext.Controller.ControllerContext.RouteData.Values[Name] = Argument;

            isValidName = true;

        }

       return isValidName;

    }

}

For razor:

<form action="" method="post">

 <input type="submit" value="Save" name="action:Save" />

 <input type="submit" value="Cancel" name="action:Cancel" />

</form>

For controller:

[HttpPost]

[MultipleButton(Name = "action", Argument = "Save")]

public ActionResult Save(MessageModel mm) { ... }

[HttpPost]

[MultipleButton(Name = "action", Argument = "Cancel")]

public ActionResult Cancel(MessageModel mm) { ... }
