This article discusses 10 features of ASP.NET 2.0 from a real-world perspective. It is not a core reference of classes and methods, but a user's guide with suggestions and trade-offs.

This article explores a comparison chart between ASP.NET 1.x and ASP.NET 2.0.

In this article we're going to cover some basic concepts on what you can do in order to make your ASP.NET application as spider and search engine friendly as possible.

A common pattern in web development is providing paged access to data. Rather than displaying the entire contents of a report or database table to an end user, developers often show only a subset of records per web page, with controls for moving from page to page. With ASP.NET 1.x, the DataGrid made paging incredibly simple - just set the AllowPaging property to True and add a few lines of code in the PageIndexChanged event handler and you were done! ASP.NET 2.0's GridView makes the process even simpler - just check the Enable Paging option from the GridView's smart tag - no code needed.

Of course nothing is free in life, and the tradeoff you make with the ease of checking a checkbox to enable paging (or, in the DataGrid's case, writing a couple lines of code) is performance. Out of the box, the DataGrid and GridView use default paging, which is a simple paging model that returns all of the records for each every page of data shown. When paging through small amounts of data (dozens to a hundred or so records), this inefficiency is likely outweighed by the ease of adding the feature. However, if you want to page through thousands, tens of thousands, or hundreds of thousands of records the default paging model is not viable.

The alternative to default paging is custom paging, in which you are tasked with writing code that intelligently grabs the correct subset of data. It requires a bit more work, but is essential when dealing with sufficiently-sized data...

Many classic ASP applications exist side-by-side with newer ASP.NET applications, sometimes leading to a need to transfer or share information between the two. This article shows one method of transferring such information securely.
