I really love Ext but coding in javascript just gives me the chills. So I went out and found a way to use my favorite js library (Ext) and my favorite programming language (C#) at the same time. By using a project called Script# I am able to write C# code and have it converted into javascript, similar to GWT. Building on that, Script# also allows you to code against external APIs, but you need to create the types, methods, properties, etc. for everything in the javascript library. So what I did was write a little console app that parses all of the ExtJS source files extracting out the script comments and writing C# files for each class. The end result is a programmable C# API to access all of the Ext objects and I threw in a couple new things to make life a little easier.

This forum post has somewhat of a history of how this project began: http://extjs.com/forum/showthread.php?t=12901

UPDATE 4/22/08

We have changed Ext# to now parse the newly released ExtJS 2.1 and we've begun recreating some of the samples using Ext#. The following Samples have been completed:

• Grids
• Basic Array Grid
• Editable Grid
• XML Grid
• Paging Grid
• Grouping Grid
• Toolbars and Menus
• Basic Toolbar
• Ext Actions
• Miscellaneous
• Data View (partial)
• Progress Bar
• Templates
• Panels
• Resizable
