C#: Enhance Enums using Extension Methods

Thu, 17 Jul 2008 11:01:02 GMT

Extension Methods are one of the coolest features that have been added in .NET 3.5. I've heard arguments that there is no reason to use them, and the only reason Microsoft added them is to enable the ability to buid LINQ. Well, I do not entirely agree with that statement; in fact, I have found a cool way to use Extension Methods to enhance the System.Enum object since it cannot be inherited. Even though Enum can not be inherited, it can be extended using Extension Methods. Here's the code to an Extension Method that extends the LocalizationMarket Enum with the ToDescriptionString() method that returns the DescriptionAttributes value for the given enum value.

Dynamic Data Access with LINQ

Wed, 02 Jul 2008 18:50:10 GMT

When I talk about LINQ people often ask whether it's possible to have dynamic queries with LINQ. An example of this is presenting the user with a UI that allows them to optionally filter by some criteria or other and sort by some criteria. This was straightforward if you built-up a SQL string in code. The compiled, static nature of LINQ makes this appear difficult at first. They are not and this video and sample application shows you how to accomplish just this.

Create In-line Data Editing with the ASP.NET 3.5 ListView Control

Thu, 22 May 2008 02:17:22 GMT

I am lovin' the total control the ListView control is giving me. This past week a link to Telerik's new RadGrid control was floating around the office - and the general consensus was that the in-line editing capabilities control was pretty cool. And I completely agree - the in-line edit feature is pretty useful. But ... you don't need to buy the RadGrid to create a grid like this. ASP.NET 3.5's ListView control provides excellent out of the box support for scenarios like this.
