ASP.NET Web Pages - Helpers

Web helpers greatly simplify Web development and common programming tasks.

ASP.NET Helpers

ASP.NET helpers are components that can be accessed with a few simple lines of Razor code.

You can build your own helpers using Razor syntax stored in .cshtml files, or use built-in ASP.NET helpers.

In the following sections of this tutorial, you will learn how to use Razor helpers.

Below are brief descriptions of some useful Razor helpers:

WebGrid Helper

The WebGrid Helper simplifies the way data is displayed:

  • Automatically creates an HTML table to display data
  • Supports different formatting options
  • Supports data paging (First, Next, Previous, Last)
  • Supports sorting by clicking column headers

Chart Helper

The "Chart Helper" can display different types of chart images with multiple formatting options and labels.

The data displayed by the Chart Helper can come from arrays, databases, or files.

The WebMail Helper provides the ability to send email using SMTP (Simple Mail Transfer Protocol).

WebImage Helper

The WebImage Helper provides functionality for managing images in web pages.

Third-Party Helpers

With Razor, you can use built-in or third-party helpers to simplify the use of email, databases, multimedia, social networks, and many other issues (such as navigation and web security).
