HtmlHelper in ASP.NET MVC – A Complete Beginner's Guide with Examples


ASP.NET MVC

ASP.NET MVC provides a powerful class called HtmlHelper that allows developers to generate standard HTML elements using model objects in Razor views. This approach promotes clean code and strong model binding.

In this guide, we’ll explore all the essential HtmlHelper methods in ASP.NET MVC, their syntax, and practical examples.


🔍 What is HtmlHelper in ASP.NET MVC?

In Razor views, @Html is an object of the HtmlHelper class. It helps generate HTML UI elements such as text boxes, labels, checkboxes, dropdowns, and more—directly from the model properties.

Html is a property of type HtmlHelper included in the base class WebViewPage.


✨ Strongly Typed vs. Loosely Typed Helpers

Method Type Description

Loosely Typed Takes string property names. Prone to runtime errors

Strongly Typed Uses lambda expressions. Compile-time safe



🔠 1. TextBox and TextBoxFor

  • TextBox() – Loosely typed
  • TextBoxFor() – Strongly typed

csharp

CopyEdit

@Html.TextBox("Name", "Umesh")

@Html.TextBoxFor(model => model.Name)

✅ TextBoxFor ensures compile-time validation of property names.


📝 2. TextArea and TextAreaFor

  • TextArea() creates multi-line input manually.
  • TextAreaFor() binds the model property to a <textarea>.

csharp

CopyEdit

@Html.TextArea("Description")

@Html.TextAreaFor(model => model.Description)

ℹ️ By default, it generates rows=2 and cols=20.


☑️ 3. CheckBox and CheckBoxFor

  • CheckBox() – Loosely typed
  • CheckBoxFor() – Strongly typed, auto-binds bool values

csharp

CopyEdit

@Html.CheckBox("IsActive", true)

@Html.CheckBoxFor(model => model.IsActive)


🔘 4. RadioButton and RadioButtonFor

Used for selecting one option from multiple.

csharp

CopyEdit

@Html.RadioButton("Gender", "Male")

@Html.RadioButtonFor(model => model.Gender, "Female")


🔽 5. DropDownList and DropDownListFor

  • Used to generate <select> elements

csharp

CopyEdit

@Html.DropDownList("City", ViewBag.Cities as SelectList)

@Html.DropDownListFor(model => model.City, ViewBag.Cities as SelectList)


🔒 6. Hidden and HiddenFor

csharp

CopyEdit

@Html.Hidden("UserId", 101)

@Html.HiddenFor(model => model.UserId)

Used to store data that should not be modified by users but is required in form submissions.


🔑 7. Password and PasswordFor

csharp

CopyEdit

@Html.Password("Password")

@Html.PasswordFor(model => model.Password)

Generates <input type="password">.


👁️ 8. Display and DisplayFor

Displays a model property as plain text (read-only).

csharp

CopyEdit

@Html.Display("Email")

@Html.DisplayFor(model => model.Email)


✍️ 9. Editor and EditorFor

Dynamically generates input elements based on the data type of the model property.

csharp

CopyEdit

@Html.Editor("Age")

@Html.EditorFor(model => model.Age)

Use EditorFor() for more complex models or data annotations.


🏷️ 10. Label and LabelFor

csharp

CopyEdit

@Html.Label("Username")

@Html.LabelFor(model => model.Username)

Generates <label> elements for form fields.

RadioButton @Html.RadioButton("G", "M") @Html.RadioButtonFor(m => m.Gender, "F")

DropDownList @Html.DropDownList("City") @Html.DropDownListFor(m => m.City, ...)

Hidden @Html.Hidden("ID") @Html.HiddenFor(m => m.ID)

Password @Html.Password("Pwd") @Html.PasswordFor(m => m.Password)

Display @Html.Display("Email") @Html.DisplayFor(m => m.Email)

Editor @Html.Editor("Age") @Html.EditorFor(m => m.Age)

Label @Html.Label("Username") @Html.LabelFor(m => m.Username)



❓ FAQ – HtmlHelper in ASP.NET MVC

1. What is the use of HtmlHelper in ASP.NET MVC?

HtmlHelper generates HTML form controls dynamically using model properties, enabling clean separation of view logic.

2. What’s the difference between TextBox and TextBoxFor?

TextBox() is loosely typed, requires a string; TextBoxFor() is strongly typed and uses lambda expressions, providing compile-time checking.

3. When should I use EditorFor over TextBoxFor?

EditorFor() is best for generating UI automatically based on data type and annotations.

4. How do I bind a dropdown list using HtmlHelper?

Use DropDownListFor() with a SelectList to bind a model property to a list of options.

5. Is HtmlHelper only for forms?

While primarily used for forms, HtmlHelper also generates display elements like labels and read-only fields.

6. Can I customize the HTML output?

Yes. All methods accept HTML attributes as an anonymous object.

csharp

CopyEdit

@Html.TextBoxFor(m => m.Name, new { @class = "form-control" })
