Create MVC HTML Controls in ASP .Net MVC

HTML Controls in MVC

HTML controls are an essential part of building web applications using the Model-View-Controller (MVC) pattern. These controls allow you to create user interfaces and gather input from users. In the MVC framework, HTML controls are typically generated using HTML Helpers, which are utility methods provided by the MVC framework.

What is HTML Helper?

HTML Helpers are methods in the MVC framework that generate HTML controls and other HTML elements. They simplify the process of generating HTML code and provide a convenient way to interact with HTML controls in an MVC application. HTML Helpers generate the necessary HTML markup based on the provided parameters and model data.

To use HTML Helpers, you need to include the necessary namespaces in your views or create custom HTML Helpers if needed.

Here are examples of some commonly used HTML controls in MVC:

Create Textbox

To create a textbox using an HTML Helper in MVC, you can use the TextBoxFor method. This method generates a text input control and associates it with a model property.

Example code:

csharp
@Html.TextBoxFor(m => m.FirstName)

Explanation: The TextBoxFor method takes a lambda expression as a parameter, which specifies the model property to which the textbox is bound. In this example, the textbox is bound to the FirstName property of the model.

Create TextArea

To create a textarea using an HTML Helper in MVC, you can use the TextAreaFor method. This method generates a textarea control and associates it with a model property.

Example code:

csharp
@Html.TextAreaFor(m => m.Description)

Explanation: The TextAreaFor method takes a lambda expression as a parameter, which specifies the model property to which the textarea is bound. In this example, the textarea is bound to the Description property of the model.

Create CheckBox

To create a checkbox using an HTML Helper in MVC, you can use the CheckBoxFor method. This method generates a checkbox control and associates it with a boolean model property.

Example code:

csharp
@Html.CheckBoxFor(m => m.IsSubscribed)

Explanation: The CheckBoxFor method takes a lambda expression as a parameter, which specifies the boolean model property to which the checkbox is bound. In this example, the checkbox is bound to the IsSubscribed property of the model.

Create Radio button

To create a radio button using an HTML Helper in MVC, you can use the RadioButtonFor method. This method generates a radio button control and associates it with a model property.

Example code:

csharp
@Html.RadioButtonFor(m => m.Gender, "Male")
@Html.RadioButtonFor(m => m.Gender, "Female")

Explanation: The RadioButtonFor method takes a lambda expression as the first parameter, which specifies the model property to which the radio button is bound. The second parameter specifies the value associated with the radio button. In this example, the radio buttons are bound to the Gender property of the model, with the values "Male" and "Female".

Create DropDownList

To create a dropdown list using an HTML Helper in MVC, you can use the DropDownListFor method. This method generates a select element and associates it with a model property.

Example code:

csharp
@Html.DropDownListFor(m => m.CityId, Model.Cities)

Explanation: The DropDownListFor method takes a lambda expression as the first parameter, which specifies the model property to which the dropdown list is bound. The second parameter specifies the list of options for the dropdown list. In this example, the dropdown list is bound to the CityId property of the model, using the options provided by the Model.Cities property.

Create Hidden field

To create a hidden field using an HTML Helper in MVC, you can use the HiddenFor method. This method generates a hidden input control and associates it with a model property.

Example code:

csharp
@Html.HiddenFor(m => m.UserId)

Explanation: The HiddenFor method takes a lambda expression as a parameter, which specifies the model property to which the hidden field is bound. In this example, the hidden field is bound to the UserId property of the model.

Create Password field

To create a password field using an HTML Helper in MVC, you can use the PasswordFor method. This method generates a password input control and associates it with a model property.

Example code:

csharp
@Html.PasswordFor(m => m.Password)

Explanation: The PasswordFor method takes a lambda expression as a parameter, which specifies the model property to which the password field is bound. In this example, the password field is bound to the Password property of the model.

Create Display field

To create a display field using an HTML Helper in MVC, you can use the DisplayFor method. This method generates a non-editable text display control for a model property.

Example code:

csharp
@Html.DisplayFor(m => m.FullName)

Explanation: The DisplayFor method takes a lambda expression as a parameter, which specifies the model property to be displayed. In this example, the display field shows the value of the FullName property of the model.

Create Label

To create a label for an HTML control using an HTML Helper in MVC, you can use the LabelFor method. This method generates a label element associated with a model property.

Example code:

csharp
@Html.LabelFor(m => m.FirstName)

Explanation: The LabelFor method takes a lambda expression as a parameter, which specifies the model property for which the label is generated. In this example, the label is generated for the FirstName property of the model.

Create Editor field

To create a rich text editor field using an HTML Helper in MVC, you can use the EditorFor method. This method generates a rich text editor control and associates it with a model property.

Example code:

csharp
@Html.EditorFor(m => m.Content)

Explanation: The EditorFor method takes a lambda expression as a parameter, which specifies the model property to which the rich text editor is bound. In this example, the rich text editor is bound to the Content property of the model.

By using these HTML Helpers, you can easily generate and customize various HTML controls in an MVC application, simplifying the development process and enhancing user interactivity.
