Question

How to pass a default value to a model bound input? its not working

@Html.TextBoxFor(model => model.City, new { @class="ctype", value="default city"})  

Answer 1

You could do this in the controller action rendering this view:

public ActionResult Index()
{
    SomeViewModel model = ...
    model.City = "default value";
    return View(model);
}

and then:

@Html.TextBoxFor(model => model.City, new { @class = "ctype" })

or if you want to use the HTML5 placeholder attribute you could do the following:

@Html.TextBoxFor(model => model.City, new { @class = "ctype", placeholder = "default value" })

or if you use a weakly typed helper (absolutely not recommended):

@Html.TextBox("City", "default value", new { @class = "ctype" })
