How to set the selected value in EnumDropDownListFor? - asp.net-mvc-5.1

Question

I'm using MVC 5.2.0 and I'm trying to use the new Html.EnumDropDownListFor. This is how I'm setting the values:
//Model
public class MyModel {
public int SelectedEnumId { get; set; }
public TestEnum MyEnum { get; set; }
}
//Enum
public enum TestEnum : int
{
name1 = 1,
name2 = 2
}
//View
#Html.EnumDropDownListFor(model => model.MyEnum,new { #class = "form-control" })
This is working and the values are being displayed. But how do I set the selected value (SelectedEnumId)?
Normally I would use
//Not enum
#Html.DropDownListFor(model => model.SelectedId, new SelectList(Model.myvalues, "Value", "Text"))
Is there a way to do this with the new Helper in MVC 5.1-5.2? Or I have to create a Extension method for this?

As far as I know just make sure the value you want to be selected is set in your Model before you call
//Controller:
...
myModel.TestEnum = TestEnum.name2;
...
//On your view
...
#Html.EnumDropDownListFor(model => model.TestEnum);
...

Could NOT get the option selected in the controller to display on the front end either, so had to resort to setting a temporary hidden input and used jQuery to update on the client side:
<div class="form-group">
#Html.LabelFor(model => model.MyEnum, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EnumDropDownListFor(model => model.MyEnum, "Select name", new { #class = "form-control" })
#Html.ValidationMessageFor(model => model.MyEnum, "", new { #class = "text-danger" })
</div>
#Html.Hidden("MyEnumTemp", (int)Model.MyEnum)
<script>
$(function () {
$("#MyEnum").val($("#MyEnumTemp").val());
});
</script>

Just Use This in Your Controller, It works like a charm
MyModel.TestEnum = (TestEnum)SelectedEnumId;
Not This will work fine assuming the case, that SelectedEnumId > 0.
if(SelectedEnumId > 0) {
MyModel.TestEnum = (TestEnum)SelectedEnumId;
}

Answer 4

public class MyModel{
public int SelectedEnumId { get { return Convert.ToInt32(this.MyEnum); } }
public TestEnum MyEnum { get; set; }
}
//add your model and after use DropDownList with EnumHelper, behaves asEnumDropDownListFor
#Html.DropDownListFor(model => model.SelectedEnumId, EnumHelper.GetSelectList(typeof(TestEnum)),new { #class="form-control" })

I know this thread is old, but I have same issue today and got it fixed; so just wanna share my codes.
you are so closed actually, all you need is to add EnumHelper.GetSelectList inside new SelectList.
//Model
public class MyModel {
public int SelectedEnumId { get; set; }
}
//Enum
public enum TestEnum
{
name1 = 1,
name2 = 2
}
//View
// get default value
var selectedID = Model.MyModel.SelectedEnumId.ToString();
// dropdown list
#Html.DropDownListFor(model => model.MyModel.SelectedEnumId, new SelectList(EnumHelper.GetSelectList(typeof(TestEnum)), "Value", "Text", selectedID), new { #class = "form-control" })
EnumHelper.GetSelectList will assign Text and Value attributes to Enum class, and use SelectedValue property of SelectList for default selected option.
Hope this will help someone. Thanks
