Working with Data in ASP.NET 2.0 - Efficiently Paging Through Large Amounts of Data
As we discussed in the preceding tutorial, paging can be implemented in one of two ways:
- Default Paging – can be implemented by simply checking the Enable Paging option in the data Web control’’s smart tag? however, whenever viewing a page of data, the ObjectDataSource retrieves all of the records, even though only a subset of them are displayed in the page
- Custom Paging – improves the performance of default paging by retrieving only those records from the database that need to be displayed for the particular page of data requested by the user? however, custom paging involves a bit more effort to implement than default paging

ADO.NET DataEntities and WCF Feeding a Silverlight DataGrid
Key to virtually every business application is the ability to move data from a database to the User Interface. While there are many issues to discuss in great detail, this tutorial will take a “drop line” approach – the shortest possible path using the simplest technology to demonstrate one way of moving data from there to here. This is not the only way, far from it, but it is a very easy way and all the parts fit together very nicely.

Structural Design Patterns and .NET Framework 2.0
There are many uncertainties in identifying and applying suitable design patterns while designing applications. Our goal is to investigate applications of design patterns in .NET Framework. Among the seven structural patterns described by Gang of Four (GOF), we have discussed five patterns from .NET perspective. As there is no official documentation available on the patterns used in the latest version of .NET Framework (version 2.0) currently, this study would be beneficial for .NET designers in understanding patterns behind the framework, which in turn would help them in applying relevant patterns while developing their aplications in .NET Framework.

GPU programming using .NET languages
Our project, which is called IL Shader, allows writing vertex and fragment programs using general purpose programming languages on .NET platform. Our project is based on three-stage translation. First, MSIL bytecode is translated to assembly language of abstract machine with vector registers. Then we perform some optimization and finally translate abstract machine code to one of assembly language shaders (currently DirectX pixel and vertex shaders). We provide infrastructure that allows using .NET classes as shaders. This project is supported by Microsoft Research grant.
