带有枚举的MVC3 RadioButtonFor

Question

I'm having problems with the HtmlHelper, RadioButtonFor and an enum in my model. I have a strongly typed view, and I want the checkboxes to toggle my enum property.

Enum.cs

public enum Values{
    Value1,
    Value2
}

---

Model.cs

public class Model{
    public Values MyProp{ get; set; }
;

---

View.cshtml

@Html.RadioButtonFor(model => model.MyPropi, Values.Values1)

---

Controller.cs
public ActionResult WizardFirstStep()
{
    var model = new Model();
    return View(model);
}

If I set the MyProperty value in the controller, the RadioButton is checked as expected. But after a post to the next wizard step, which gets the model as parameter, the property isn't set.

If it will help you to understand what I mean: If it would be C# and WPF I would use a IValueConverter.

btw: I use a HtmlHelper.ActionLink to get the model to the controller.

Thanks in advance

Answer 1

Try this, it should work as I have done the same thing before:

@Html.RadioButtonFor(model => model.MyProp, (int)Values.Values1, model.MyProp == Values.Values1)

Notice the cast to int , it ensures the correct value is used for html.

EDIT : Sorry, I think you also need the third parameter to ensure the correct radio button is set when loading the view.

I also assumed MyPropi was a typo and changed it to MyProp , please ensure this matches up correctly at your end

Answer 2

Sorry for any inconvenience. After posting here, I found the solution very quickly. My ActionLink was not submitting the @Html.BeginForm form. So i changed my radiobutton to:

@Html.RadioButtonFor(model => model.MyPropi, Values.Values1, new{ onClick = "this.form.submit();" })

which submits the correct value to my controller. For the moment this is okay. Maybe the ActionLink can post back the form data.

对于Aspx页面：<％：Html.RadioButtonFor（m => m.YourProp，您的枚举的选定值，如：demo1.enum1.value2）
