Using Page Inspector in Visual Studio 11

Version: 1.2.0

Description

Page Inspector is a new tool that brings browser diagnostics tools into Visual Studio and provides an integrated experience between the browser, ASP.NET, and source code. It renders a web page (HTML, Web Forms, ASP.NET MVC, or Web Pages) directly within Visual Studio 11 and lets you examine both the source code and the resulting output. Page Inspector enables you to easily decompose a website, rapidly build pages from the ground up, and quickly diagnose issues. In this lab, you will explore how to use Page Inspector.

Overview

In this Hands-on Lab, you will discover a new tool to find and fix web page issues in Visual Studio - the Page Inspector.

Page Inspector is a new tool that brings browser diagnostics tools to Visual Studio and provides an integrated experience among the browser, ASP.NET, and source code. It renders a web page (HTML, Web Forms, ASP.NET MVC, or Web Pages) directly within the Visual Studio IDE and lets you examine both the source code and the resulting output. Page Inspector enables you to easily decompose a website, rapidly build pages from the ground up, and quickly diagnose issues.

Nowadays we have a number of Web frameworks that create flexible and scalable websites in a timely manner, such as ASP.NET MVC and WebForms. On the other hand, it gets harder to find issues on the pages because the IDE does not support the designer view in template-based pages and dynamic content. Therefore, these websites have to be opened in a browser to see how they appear to a user.

Web developers use external tools to find issues that regularly run in the browser. Then, they return to the IDE and start fixing. This back and forth activity among the IDE, the browser and the profiling tools can be inefficient, and sometimes requires a fresh deployment and cache cleaning each time you want to reproduce an issue.

Page Inspector bridges a gap in Web development between the client (browser tools) and the server (ASP.NET and source code) by bringing together the best of both worlds using a combined set of features.

Using Page Inspector, you can see which elements in the source files (including server-side code) have produced the HTML markup to be rendered in the browser. Page Inspector also lets you modify CSS properties and DOM element attributes to see the changes reflected immediately in the browser.

This hands-on lab will walk you through the Page Inspector features and show you how you can use them to fix issues in Web applications. This lab contains two exercises using similar flows but targeting different technologies. If you are an ASP.NET MVC Developer, follow exercise one; if you are a WebForms developer follow exercise two.

Objectives

In this hands-on lab, you will learn how to:

  • Decompose a Web Site using Page Inspector
  • Inspect and preview CSS styles changes with Page Inspector
  • Detect and fix issues in your web pages using Page Inspector

Prerequisites

  • Microsoft Visual Studio 11 Beta
  • Page Inspector (included in the Microsoft Visual Studio 11 Beta installation)
  • Internet Explorer 9
  • ASP.NET MVC 4 (only if you are performing exercise 1; included in the Microsoft Visual Studio 11 Beta installation)
Note:
Page Inspector hosts the current version of Internet Explorer in Visual Studio. For full functionality, you must have Internet Explorer 9 installed on your computer. You do not need to have Internet Explorer Platform Preview (also called Internet Explorer 10 Test Drive) installed.

Exercises

This hands-on lab includes the following exercises:

  1. Using Page Inspector in ASP.NET MVC Projects
  2. Using Page Inspector in WebForms Projects
Note:
Each exercise is accompanied by a starting solution—located in the Begin folder of the exercise—that allows you to follow each exercise independently of the others. Inside the source code for an exercise, you will also find an End folder containing a Visual Studio solution with the code that results from completing the steps in the corresponding exercise. You can use these solutions as guidance if you need additional help as you work through this hands-on lab.
