The .NET Framework is an enormous collection of tools for programmers (and, like the world and all it contains, not a subject we have to get into right now). Suffice it to say that all ASP.NET Web server controls you find in VWD are members of the .NET Framework. And as such, complete documentation about any server control is available from the .NET Framework online documentation. In Visual Web Developer, the Toolbox shows the names of commonly used .NET Server controls, categorized into groups like Data, Validation, Navigation, Login, and so forth. These tools are visible only when you re editing a Web form (.aspx page). The server controls are hidden when you re editing an .HTML page. Adding a Server Control to a Page Adding a server control to a page is pretty simple: You drag its name from the Toolbox onto your page. You can put server controls on a blank .aspx page, in Master Pages, or in the content placeholder in a page that uses a Master Page. The size and complexity of server controls ranges from a tiny link on a page with a few properties to multipage wizards consisting of many smaller controls and many properties, and every size in between. Despite the differences among server controls, there are some commonalities in how you work with them. Those commonalities are what this chapter is mostly about. As mentioned, adding a server control to a page is simple: You just drag its name from the Toolbox to wherever you want to place it on the page. In Figure 7-2, for example, I ve created a page named Login.aspx and placed a table (along with some text) on the page. In the figure, I ve just dragged a Login control from the Toolbox into the lower-right cell of the table. Drag Figure 7-2: Using data and .aspx pages to create HTML.
