The HtmlHelper class includes two extension methods TextBox() and TextBoxFor<TModel, TProperty>() that renders the HTML textbox control <input type="text"> in the razor view. It is recommended to use the generic TextBoxFor<TModel, TProperty>() method, which is less error prons and performs fast.
Both of them provide the same HTML output, “HTML. TextBoxFor” is strongly typed while “HTML. TextBox” isn't. Below is a simple HTML code which just creates a simple textbox with “CustomerCode” as name.
The TextBoxes can be made ReadOnly by setting the HTML ReadOnly attribute using the HtmlAttributes parameter in Html. TextBox and Html. TextBoxFor helper functions.
You can make the input 'read only' by using 'readonly'. This will let the data be POSTED back, but the user cannot edit the information in the traditional fashion. Keep in mind that people can use a tool like Firebug or Dragonfly to edit the data and post it back.
Try this:
<%= Html.TextBoxFor(x => x.Age, new { @Value = "0"}) %>
note that @Value has a capital V
This should work for MVC3 & MVC4
@Html.TextBoxFor(m => m.Age, new { @Value = "12" })
If you want it to be a hidden field
@Html.TextBoxFor(m => m.Age, new { @Value = "12",@type="hidden" })
It turns out that if you don't specify the Model to the View method within your controller, it doesn't create a object for you with the default values.
[AcceptVerbs(HttpVerbs.Get)]
public ViewResult Create()
{
// Loads default values
Instructor i = new Instructor();
return View("Create", i);
}
[AcceptVerbs(HttpVerbs.Get)]
public ViewResult Create()
{
// Does not load default values from instructor
return View("Create");
}
The default value will be the value of your Model.Age property. That's kind of the whole point.
You can simply do :
<%= Html.TextBoxFor(x => x.Age, new { @Value = "0"}) %>
or better, this will switch to default value '0' if the model is null, for example if you have the same view for both editing and creating :
@Html.TextBoxFor(x => x.Age, new { @Value = (Model==null) ? "0" : Model.Age.ToString() })
This work for me
@Html.TextBoxFor(model => model.Age, htmlAttributes: new { @Value = "" })
