This chapter covers
- Using the view bag and temp data to pass data from an action to a view
- Using layouts to define common content
- Using partial views to define reusable sections of content
- Encoding data within views
In this chapter, I describe more of the features provided by Razor Views. I show you how to pass additional data to a view using the view bag and how to use layouts and layout sections to reduce duplication. I also explain how the results from expressions are encoded and how to disable the encoding process. Table 22.1 provides a guide to the chapter.
