The all-new approach for experienced ASP.NET professionals!

ASP.NET is Microsoft's technology for building dynamically generated web pages from database content. Originally introduced in 2002, ASP.NET has undergone many changes in multiple versions and iterations as developers have gained a decade of experience with this popular technology. With that decade of experience, this edition of the book presents a fresh, new overhauled approach.

  • A new focus on how to build ASP.NET sites and applications relying on field-tested reliable methods
  • Integration of "One ASP.NET" philosophy treating ASP.NET Web Forms and ASP.NET MVC as equal tools each with their proper time and place
  • Coverage of hot new ASP.NET 4.5 additions such as the Web API, Websockets and HTML5 & CSS3 use in layout but only to the extent that the tools themselves are practical and useful for working ASP.NET developers

Professional ASP.NET 4.5 in C# and VB is an essential tool for programmers who need to be productive and build reliably performing sites with the latest ASP.NET Framework and Visual Studio.

LocalDB. Regardless of the database used, the database is named using the fully qualified name of the derived context. In this example, the database name is AspnetEntityFX.TeamContext.

e) { if (!Page.IsPostBack) { Label1.Text = System.Guid.NewGuid().ToString(); } } Now you have a Label control on the master page that you can access from the content page: Using FindControl() Using a custom property You have a couple of ways to accomplish this task. The first way is to use the FindControl() method that the master page exposes. Listing 16-9 shows this approach.

members are contained within that particular role (so that you don’t accidentally delete a role with users in it when you don’t mean to): Roles.DeleteRole(rolename As String) Roles.DeleteRole(rolename As String, throwOnPopulatedRole As Boolean) Listing 19-31 is a partial code example that builds on Listing 19-30. For this example, you add an additional button that initiates a second button-click event that deletes the role from the service. LISTING 19-31: Deleting roles from the application VB
