This is a perfect scenario to create your own custom action filter attribute! This is easy! All you need to do is create a class that inherits ActionMethodSelectorAttribute. This is different from inheriting from the ActionFilterAttribute class as that's the base class for all action filter attributes. If I was... |

This topic demonstrates how to create a Web page and user control that use the CodeBehind attribute of the @ Page directive, compile them, and then convert them to use the CodeFile attribute with a partial class in the code-behind files in the .NET Framework version 2.0. The new Web page code-behind model in ASP.NET version 2.0 is based on partial classes. The markup for the page is stored in one file – the .aspx file – and the code is defined in a partial class – the code-behind file. Convertin... |

Introduction to Aspect Oriented Programming (AOP) is mostly done by exercising an example, adding logging as an aspect to an existing application. But, it is really simple to realise more sophisticated functionality using AOP. This article will demonstrate the use of aspects to build an easy to integrate and extensible permission management. This is done by applying custom attributes to methods, and checking these attributes while invoking annotated methods.... |
