Question

I’m having a little trouble with something.

I have an HttpGet method like this:

[HttpGet]
public ActionResult Form()
{
    MyModel model = new MyModel();
    model.something = "hi";
    return View(model);
}

In my model:

public string something { get; set; }

[Display(Name="Something Else:")]
public string somethingelse { get; set; }

And in my view i have a form:

@model Path.To.Models.MyModel

@Html.TextBoxFor(model => model.somethingelse)

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

The problem is after the form is submitted, model.something is coming back as null instead of what I expect, which is “hi”

Here’s my HttpPost

[HttpPost]
public ActionResult Form(MyModel model)
{
    // model.somethingelse equals the form value, which is right
    // model.something is null, instead of what I expect - "hi"

    return View(model);
}

Can anyone help me with this? I need to get the data from the GET to the POST after the form submission, but it’s coming back null.

Thanks

Answer 1

you have to put the “unchanged values” in hidden fields in your view

@Html.HiddenFor(m => m.something) 

or it won’t be passed !
