ASNA WingsRPG™ Reference Manual

ASP.NET Code-Behind

ASP.NET provides two ways to construct pages: In-line coding and code-behind. The in-line coding method has the code embedded right in the ASPX page, while the code-behind method provides a separate class file with an extension of .cs for C#, .vb for Visual Basic, and .vr for ASNA Visual RPG. ASNA Wings uses the code-behind method to allow for the separation of the presentation layer ASPX, and the programming code-behind that interacts with the presentation layer and the client and server.

For instance, the following is an example of the code-behind in the Sign-On.aspx.vr file provided with the initial installation of ASNA Wings. This code defines the assemblies used, defines partial class SignOn as ASNA.Monarch.WebDspF.Page and the method Page_Load, which controls the presentation of the ASPX file to the user. Refer to What is an ASPX Page for more information.
