MVC5 - How to set “selectedValue” in DropDownListFor Html helper

Question

As the question says: How to set selectedValue in DropDownListFor Html helper?

Tried most of the other solutions but none worked that\'s why I am opening a new quest

Answer 1

public static class EnumHelper
{
    public static SelectList EnumToSelectList(this Type enumType, object selectedValue)
    {  
        return new SelectList(Enum.GetValues(enumType).Cast().ToList().ToDictionary(n=> n), "Key", "Value", selectedValue);
    }
}

And in your View:

@Html.DropDownListFor(model => model.Role, EnumHelper.EnumToSelectList(typeof(Role), Model.Role),  new { htmlAttributes = new { @class = "padding_right" } })
@Html.ValidationMessageFor(model => model.Role, "", new { @class = "text-danger" })

Instead of EnumToList use any Other List and select Key and Value of your Listtype Properties
