How do I have a default selected enum using EnumDropDownListFor?

In my MVC5 app I have a page which shows logs.

I have a drop down to filter logging levels, which are:

I have these defined an an enum called ErrorLevel:

public enum ErrorLevel
{
    [Description("All")]
    All = 0,

    [Description("Debug")]
    Debug = 1,

    [Description("Error")]
    Error = 2,

    [Description("Info")]
    Info = 3
}

I am rendering these in my view like this:

@Html.EnumDropDownListFor(model => model.Level)

The drop down value is blank when the page first renders - how do I have All as the default selected enum value when the page first renders?

I've spent 20 minutes looking for how to do this but can't find how to do it, can anyone help?

Hi you can easily do that, in the constructor of the model class within controller .

Here is the complete example:

Sample Modal Class:

 public class SampleModel
    {
        public ErrorLevel level{ get; set; }
    }

Enum:

  public enum ErrorLevel
{
    [Description("All")]
    All = 0,

    [Description("Debug")]
    Debug = 1,

    [Description("Error")]
    Error = 2,

    [Description("Info")]
    Info = 3
}

Some Controller :

public class HomeController : Controller
{

    public ActionResult Index()
    {
        SampleModel samplemodel= new SampleModel {level= level.All};  //you can set any value which you want as default
        return View("View",samplemodel);
    }
}

Hope the above code was helpful

Thanks

You can do this by setting the Enum in the Model before it gets called in the view.

Controller 

 model.Level = ErrorLevel.All;
