Passing variables with POST in ASP.NET MVC

Question

I am trying to pass a string variable inside asp.net MVC. I use breakpoints so I see that it does go to the correct method in the controller, but the variables posted are equal

On a slightly separate note there is nothing wrong with passing variables like you are, but a more efficient way would be to pass around a strongly typed view model allowing you to take advantage of many aspects of MVC's goodness:

• strongly-typed views
• MVC Model Binding
• Html Helpers

Create a new view model:

public class TestModel
{
    public string TestInput { get; set; }
}

Your test controller:

    [HttpGet]
    public ActionResult TestForm()
    {
        return View();
    }

    [HttpPost]
    public ActionResult TestForm(FormCollection collection)
    {
        var model = new TestModel();
        TryUpdateModel(model, collection);

        Response.Write("[" + model.TestInput + "]");

        return View();
    }

Your view:

@model .Models.TestModel

@{
    Layout = null;
}





    


    

        @using(Html.BeginForm())
        {
            

                @Html.LabelFor(m => m.TestInput)
            
            

                @Html.TextBoxFor(m => m.TestInput)
            
            
        }
