Html.TextBox() 4.1Overloads 5. Conclusion Introduction An HTML Helper is nothing more than a string-returning method. The HTML helper is a mechanism for rendering HTML material in a view. An extension method is used to implement HTML helpers. HTML controls are rendered in the razor view by the HTMLHelper class. while submitting a web form, it binds the model object to HTML controls to show the value of model properties in those controls and also assigning the values of the control to the model properties. The use of the HtmlHelper class in the razor view is shown in the following figure. Source: HTML Helpers @Html is an object of the HtmlHelper class in the above figure. In razor syntax, the @symbol is used to access a server-side object. Html is a property of the HtmlHelper class, which is included in the WebViewPage base class. The HtmlHelper class includes extension methods such as ActionLink() and DisplayNameFor(). HTML elements are generated by the HtmlHelper class. For Example, @Html.ActionLink("Create New", "Create") would produce anchor tag Create New. The HtmlHelper class has many extension methods, so you can use extension method for HtmlHelper class for creating the various HTML controls. The HtmlHelper methods and HTML controls rendered by each method are listed in the table below. Extension Method Strongly Typed Method Html Control Html.ActionLink() NA   Html.TextBox() Html.TextBoxFor() Html.TextArea() Html.TextAreaFor() Html.CheckBox() Html.CheckBoxFor() Html.RadioButton() Html.RadioButtonFor() Html.DropDownList() Html.DropDownListFor() multi-select list box: Html.ListBox() Html.ListBoxFor() Html.Hidden() Html.HiddenFor() Html.Password() Html.PasswordFor() HTML text: "" Html.Display() Html.DisplayFor() HTML text: "" Html.Label() Html.LabelFor()   Html.Editor() Html.EditorFor() Creates HTML controls based on the data type of a model property, such as a numeric field for a double, a textbox for a string property, double, or other numeric types. The difference between utilizing HTML tags and calling the HtmlHelper methods is that the HtmlHelper method is designed to make it simple to bind to view or model data. Now, we will learn more about Textbox HTMLHelper in MVC: Create a Textbox in ASP.NET MVC TextBox() and TextBoxFor TModel, TProperty() are two extension methods in the HtmlHelper class that render the HTML textbox control input type="text" in the razor view. Generally, The generic TextBoxFor() method is used for faster performance and fewer prons for errors. Throughout this blog, we will use the Employee model class. Example   public class Employee { public int EmployeeId { get; set; } [Display(Name = "Name")] public string EmployeeName { get; set; } public int Age { get; set; } public string Salary { get; set; } public bool IsActive { get; set; } public string Password { get; set; } } Html.TextBoxFor() TextBoxFor() is a generic extension method that produces a control with the input type="text". The model class is specified by the first type parameter, whereas the property is specified by the second type parameter. As a result, it displays the value of the model property in a textbox and Visa-versa. The following code demonstrates how to render a textbox for the Employee model's EmployeeeName property. Example   @model Employee @Html.TextBoxFor(m => m.EmployeName) The lambda expression m => m.EmployeeName specifies the EmployeeName property to bind with a textbox in the example above. As demonstrated below, it creates an input text element with id and name attributes. Html Result: The class attribute is used to render a textbox in the below example. Example   @model Employee @Html.TextBoxFor(m => m.EmployeeName, new { @class = "form-control" }) Html Result: There are many overloads of the TextBoxFor() method and it can be applied to the Asp.Net MVC 5.2 and above version as follows: Read More: Generate Thumbnail Using Asp.net Overloads TextBoxFor(HtmlHelper,Expression>, String) It returns a text input element. public static System.Web.Mvc.MvcHtmlString TextBoxFor(this System.Web.Mvc.HtmlHelper htmlHelper, System.Linq.Expressions.Expression> expression, string format); Type Parameters TModel: It is the type of model.

Exceptions ArgumentException The expression parameter is null or empty. TextBoxFor(HtmlHelper,Expression>,IDictionary) Using the specified HTML attributes it returns a text input element for each property in the object represented by the expression.   public static System.Web.Mvc.MvcHtmlString TextBoxFor(this System.Web.Mvc.HtmlHelper htmlHelper, System.Linq.Expressions.Expression> expression, System.Collections.Generic.IDictionary htmlAttributes); Type Parameters   TModel: It is the type of model.

CONNECT US Html.TextBox() The TextBox() method creates an HTML control input type="text" with the supplied vaslue, name and other attributes. public static MvcHtmlString TextBoxFor(this HtmlHelper> htmlHelper, Expression> expression, object htmlAttributes); Because the name parameter in TextBox() is a string, it is a weakly typed method. A model object's property name can be used as the name parameter. It binds a textbox with a specific property. Example @model Employee @Html.TextBox("EmployeeName") Html Result: There are many overloads of the TextBox() method and it can be applied to the Asp.Net MVC 5.2 and above version as follows: Overloads TextBox(HtmlHelper, String, Object, String, Object) It returns a text input element. public static System.Web.Mvc.MvcHtmlString TextBox(this System.Web.Mvc.HtmlHelper htmlHelper, string name, object value, string format, object htmlAttributes); Parameters htmlhelper HtmlHelper This method extends an HTML helper instance. name String The form field’s name and the ViewDataDictionary key for looking up the value value Object It is the text input element's value.
