Tag Helpers - ( ASP.NET Core MVC )

Tag Helpers are a feature of ASP.NET Core MVC that allow you to create server-side HTML elements that interact with server-side models and data. Tag Helpers can be used to generate HTML elements, create form controls, and even link to other pages. In this page, we will discuss Tag Helpers and how to use them in your ASP.NET Core MVC application.

Syntax

The syntax for Tag Helpers is similar to HTML attributes. Here is an example of a simple Tag Helper that generates a div element:

<div asp-my-tag-helper></div>

Example

Here's an example of how to use Tag Helpers in an ASP.NET Core MVC application. Suppose you have a model named Product with the properties Name and Description. You could create a form using Tag Helpers in the following way:

<form asp-action="Create" asp-controller="Product" method="post">
    <div class="form-group">
        <label asp-for="Name" class="control-label"></label>
        <input asp-for="Name" class="form-control" />
    </div>
    <div class="form-group">
        <label asp-for="Description" class="control-label"></label>
        <textarea asp-for="Description" class="form-control"></textarea>
    </div>
    <button type="submit" class="btn btn-primary">Create</button>
</form>

In this example, the asp-for attribute is used to bind the form controls to the corresponding properties of the Product model. The asp-action and asp-controller attributes specify the action and controller that handle the form submission.

Output

Tag Helpers generate HTML elements that are interpreted by the browser in the same way as regular HTML elements. However, because Tag Helpers are generated on the server side, they can be used to interact with server-side models and data.

Explanation

Tag Helpers allow you to create server-side HTML elements that can be used to interact with server-side models and data. Tag Helpers are processed on the server side and generate HTML elements on the client side. Tag Helpers can be used to generate HTML elements, create form controls, and even link to other pages.

Use

Tag Helpers are useful for creating server-side HTML elements that interact with server-side models and data. Tag Helpers can be used to generate HTML elements, create form controls, and even link to other pages.

Important Points

• Tag Helpers have a similar syntax to HTML attributes.
• The asp-for attribute is used to bind form controls to server-side models and data.
• Tag Helpers can be used to generate HTML elements, create form controls, and even link to other pages.

Summary

Tag Helpers are a feature of ASP.NET Core MVC that allow you to create server-side HTML elements that interact with server-side models and data. Tag Helpers can be used to generate HTML elements, create form controls, and even link to other pages. By leveraging the power of Tag Helpers, you can create powerful and dynamic server-side applications with ease.
