Working on a multi-developer ASP.NET project while sharing one web.config can be time consuming and troublesome. Usually, each developer may have path and other settings specific to their development machine, such as Database connection strings, paths, e-mail addresses, etc. For example, each developer on a project may be running a database locally that the application relies on during development. Therefore, the connection string would be different for each developer.

Ideally, every application built would be designed with correct date handling techniques. In practice, applications are often built using ad hoc date formatting to match a corporate culture, the default format on a company�s server, or the favorite format of the lead developer. Also, many applications are not locale aware or were not designed to be deployed in an environment where locale issues were not considered important. Because of this it is extremely important to know the date formats in use for input and output when building applications that will integrate with other systems or databases and to handle these formats explicitly.

ASP.Net's introduction of the web.config file went a long way to filling the configuration hole we had to deal with in classic ASP. We actually went from having very little (global.asa was the closest thing) to a well-structured, change on the fly XML file. For the most part, the web.config file does the trick fine. However there are some limitations and constraints with using it, which you are probably already aware of. What you might not know is how easy is it to surmount those issues by creating a far more flexible alternative.

With a solid foundation created in Part 1, we now turn our attention to more advanced topics. We�ll use context rewriting for some professional looking and hassle free state-management, talk about good database design with respect to multilingual applications, and dive into more advanced Localized controls for ultimate flexibility and productivity.

This article walks you through the process of building a thin-client ASP.NET bug tracking application, with a Microsoft Access XP backend. It uses nearly every documented capability of the .NET datagrid web server control to allow you to select, edit, update, or delete any item listed in the datagrid. The Issue Tracker uses advanced features, such as reading values from lookup tables, and then conveniently providing these values to the user in Edit mode as dropdownlists. It also employs the IE Web Controls, including the Tab and MultiPane web controls, which allow you to display considerable user functionality on only one web page, yet without cluttering the user interface with confusing complexity. After working through this tutorial, you will have explored and applied all of the main functionalities of the ASP.NET DataGrid control. Happy Coding!
