Built-in Tag Helpers - (ASP.NET MVC Tag Helpers)

Tag Helpers in ASP.NET MVC are useful for generating HTML markup for server-side controls in a more natural and less verbose way. In addition to custom Tag Helpers, ASP.NET MVC also provides several built-in Tag Helpers for common tasks. In this tutorial, we'll discuss the various built-in Tag Helpers available in ASP.NET MVC.

Syntax

The syntax for using built-in Tag Helpers is similar to that of custom Tag Helpers in ASP.NET MVC, with the only difference being the name of the Tag Helper. To use a built-in Tag Helper, you need to add the appropriate HTML tag and its associated attributes to your view, as well as include its namespace.

Example

Here are some examples of built-in Tag Helpers in ASP.NET MVC:

<!-- Image Tag Helper -->
<img asp-src="@Model.ImageUrl" alt="Image">

<!-- Anchor Tag Helper -->
<a asp-controller="Home" asp-action="Index">Home</a>

<!-- Form Tag Helper -->
<form asp-action="Create" asp-controller="Products">
    <input asp-for="Name" />
    <input asp-for="Price" />
    <button type="submit">Create</button>
</form>

In the above examples, we have used the built-in img, a, and form Tag Helpers to generate corresponding HTML elements. The asp-src, asp-controller, and asp-action attributes correspond to the src attribute on the <img> tag, href attribute on the <a> tag, and action and controller attributes on the <form> tag, respectively.

Explanation

ASP.NET MVC provides a number of built-in Tag Helpers that can be used for generating common HTML elements such as images, anchors, forms, and more. These Tag Helpers are provided as a convenience and make it easier to generate markup for common tasks, allowing developers to focus more on the logic of their application and less on writing HTML.

Use

Built-in Tag Helpers are useful for generating common HTML elements in ASP.NET MVC applications. They simplify the process of generating HTML markup for server-side controls and make the code more readable and maintainable.

Important Points

Here are some important points to keep in mind when using built-in Tag Helpers in ASP.NET MVC:

• Built-in Tag Helpers are available out of the box and do not require any additional configuration.
• You can create your own custom Tag Helpers and combine them with built-in Tag Helpers to create more advanced and complex markup.
• To use a built-in Tag Helper, you must include its namespace in your view or add it to the _ViewImports.cshtml file.

Summary

In this tutorial, we discussed the various built-in Tag Helpers available in ASP.NET MVC. We covered the syntax, example, explanation, use, and important points of built-in Tag Helpers in ASP.NET MVC. With this knowledge, you can use built-in Tag Helpers in your ASP.NET MVC applications to generate common HTML elements quickly and easily.
