In this article I will explain with an example, how to set Default text (Value) attribute in TextBox using HTML.TextBoxFor and HTML.TextBox helper methods in ASP.Net MVC.
Model
The Model class consists of following property.
public class PersonModel
{
///<summary>
/// Gets or sets Name.
///</summary>
public string Name { get; set; }
}
Controller
The Controller consists of following Action method.
Action method for handling GET operation
Inside this Action method, an object of PersonModel class is created and is returned to the View. The value of the Name property will be set in the TextBox created using Html.TextBoxFor and Html.TextBox helper methods.
public class HomeController : Controller
{
// GET: Home
public ActionResult Index()
{
PersonModel person = new PersonModel
{
Name = "Mudassar Khan"
};
return View(person);
}
}
View
HTML Markup
Inside the View, in the very first line the PersonModel class is declared as Model for the View.
The View consists of two HTML INPUT TextBoxes created using Html.TextBoxFor and Html.TextBox Html helper methods.
Html.TextBoxFor
The TextBox created using Html.TextBoxFor is set with following properties:
model property – The name of the property is set using Lambda expression.
htmlAttributes – An object that contains the HTML attributes to set for the element.
Html.TextBox
The TextBox created using Html.TextBox is set with following properties:
name – The name of the form field. In Controller the TextBox value is captured using this parameter.
value – The value of the text input element.
htmlAttributes – An object that contains the HTML attributes to set for the element.
Note: In Html.TextBox helper method, the second parameter is value hence there is no need to specify any htmlAttribute like Html.TextBoxFor helper method
@model HTML_TextBox_defaultValue_MVC.Models.PersonModel
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
@Html.TextBoxFor(m => m.Name)
@Html.TextBox("Country", "India")
</body>
</html>
