Html.EditorFor Set Default Value

Rookie question. I have a parameter being passed to a create view. I need to set a field name with a default value. @Html.EditorFor(model => model.Id) I need to set this input field with name Id with a default value that is being passed to the view via an actionlink.

So, how can this input field [email protected](model => model.Id) -- get set with a default value.

Would the following work?? Where the number 5 is a parameter I pass into the text field to set default value.

@Html.EditorFor(c => c.PropertyName, new { text = "5"; })

Instead of using controller or html helper.You can also use Jquery to set default value to model attribute.

   $('#PropertyName').val(15);

For me I need to set current date and time as default value this solved my issue in View add this code :

<div class="form-group">
        @Html.LabelFor(model => model.order_date, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.EditorFor(model => model.order_date, new { htmlAttributes = new { @class = "form-control",@Value= DateTime.Now }  })
                @Html.ValidationMessageFor(model => model.order_date, "", new { @class = "text-danger" })
                
            </div>
        </div>

This worked for me:

In the controller

*ViewBag.DefaultValue= "Default Value";*

In the View

*@Html.EditorFor(model => model.PropertyName, new { htmlAttributes = new { @class = "form-control", @placeholder = "Enter a Value", @Value = ViewBag.DefaultValue} })*

This worked for me

In Controlle

 ViewBag.AAA = default_Value ;

In View 

@Html.EditorFor(model => model.AAA, new { htmlAttributes = new { @Value = ViewBag.AAA } }

This is my working code:

@Html.EditorFor(model => model.PropertyName, new { htmlAttributes = new { @class = "form-control", @Value = "123" } })

my difference with other answers is using Value inside the htmlAttributes array

Shove it in the ViewBag:

Controller:

ViewBag.ProductId = 1;

View:

@Html.TextBoxFor(c => c.Propertyname, new {@Value = ViewBag.ProductId})

Its not right to set default value in View. The View should perform display work, not more. This action breaks ideology of MVC pattern. So the right place to set defaults - create method of controller class.

In the constructor method of your model class set the default value whatever you want. Then in your first action create an instance of the model and pass it to your view.

    public ActionResult VolunteersAdd()
    {
        VolunteerModel model = new VolunteerModel(); //to set the default values
        return View(model);
    }

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult VolunteersAdd(VolunteerModel model)
    {


        return View(model);
    }

Shouldn't the @Html.EditorFor() make use of the Attributes you put in your model?

[DefaultValue(false)]
public bool TestAccount { get; set; }

I just did this (Shadi's first answer) and it works a treat:

    public ActionResult Create()
    {
        Article article = new Article();
        article.Active = true;
        article.DatePublished = DateTime.Now;
        ViewData.Model = article;
        return View();
    }

I could put the default values in my model like a propper MVC addict: (I'm using Entity Framework)

    public partial class Article
    {
        public Article()
        {
            Active = true;
            DatePublished = Datetime.Now;
        }
    }

    public ActionResult Create()
    {
        Article article = new Article();
        ViewData.Model = article;
        return View();
    }

Can anyone see any downsides to this?

Better option is to do this in your view model like

public class MyVM
{
   int _propertyValue = 5;//set Default Value here
   public int PropertyName{
       get
       {
          return _propertyValue;   
       }
       set
       {
           _propertyValue = value;
       }
   }
}

Then in your view 

@Html.EditorFor(c => c.PropertyName)

will work the way u want it (if no value default value will be there)

The clean way to do so is to pass a new instance of the created entity through the controller:

//GET
public ActionResult CreateNewMyEntity(string default_value)
{
    MyEntity newMyEntity = new MyEntity();
    newMyEntity._propertyValue = default_value;

    return View(newMyEntity);
}

If you want to pass the default value through ActionLink

@Html.ActionLink("Create New", "CreateNewMyEntity", new { default_value = "5" })

Here's what I've found:

@Html.TextBoxFor(c => c.Propertyname, new { @Value = "5" })

works with a capital V, not a lower case v (the assumption being value is a keyword used in setters typically) Lower vs upper value

@Html.EditorFor(c => c.Propertyname, new { @Value = "5" })

does not work

Your code ends up looking like this though

<input Value="5" id="Propertyname" name="Propertyname" type="text" value="" />

Value vs. value. Not sure I'd be too fond of that.

Why not just check in the controller action if the proprety has a value or not and if it doesn't just set it there in your view model to your defaulted value and let it bind so as to avoid all this monkey work in the view?
