Updating the TableAdapter to Use JOINs. When working with a database it is common to request data that is spread across multiple tables. To retrieve data from two different tables we can use either a correlated subquery or a JOIN operation. In this tutorial we compare correlated subqueries and the JOIN syntax before looking at how to create a TableAdapter that includes a JOIN in its main query. #07-23 14:00
Using UpdatePanel Inside Templated Controls. ASP.NET AJAX provides many ways to improve user experience and performance. One of the most common way is undoubtedly the UpdatePanel control. The UpdatePanel control provides partial page rendering capabilities to your web forms. Commonly developers place data bound controls such as GridView and DataList inside an UpdatePanel so that only that area of the web form is refreshed after a post back from within the UpdatePanel. However, there is still better way to use UpdatePanel with grids and lists. Don't agree? Read on to know more! #07-22 14:00

An alternative approach is to use stored procedures, where the SQL statements are pre-defined at the database. In this tutorial we learn how to have the TableAdapter Wizard generate new stored procedures for us. #07-21 14:00
Improving Performance using ODS Custom Paging. Displaying database records in paged fashion is a common requirement in web applications. ASP.NET 2.0 controls such as GridView and DetailsView have inbuilt paging capabilities. Many developers rely on inbuilt paging to speed up their job. However, inbuilt paging comes with its own price. Fortunately, Object Data Source (ODS) control also provides a way by which you can implement a custom paging scheme. Such custom paging scheme can improve performance of your web application as compared to inbuilt paging scheme. In this article I will explain with an example how the custom paging scheme of ODS works. #07-20 14:00

Pagination In SQL Server 2005. If you've used other flavors of SQL (such as MySQL or PostgreSQL) and now you have switched over to TSQL (Microsoft SQL Server) you may have noticed that there is no native way of doing pagination. In some SQL versions, pagination was as easy as "SELECT * FROM 'myTable' LIMIT 0, 10" and that would pull out the first 10 records from your table. SQL Server 2005 introduced a beautiful new world of 'ranking functions', one of which we can use to easily perform pagination directly in SQL. #07-15 14:00

Consuming Web Services With ASP.NET AJAX. One of the most powerful features of ASP.NET AJAX is often times one of the most overlooked uses - consuming web services. Many ASP.NET developers are beginning to implement AJAX into their site by the use of the drop-in-place controls such as the UpdatePanel, ModalPopup and Timer, but this can be damaging as they take focus away from the deeper things of ASP.NET AJAX. #07-13 14:00

Using SQL Cache Dependencies. The simplest caching strategy is to allow cached data to expire after a specified period of time. But this simple approach means that the cached data maintains no association with its underlying data source, resulting in stale data that is held too long or current data that is expired too soon. A better approach is to use the SqlCacheDependency class so that data remains cached until its underlying data has been modified in the SQL database. This tutorial shows you how. #06-07 14:00

Working with Transactions in ADO.NET. A transaction is a group of operations combined into a logical unit of work that is either guaranteed to be executed as a whole or rolled back. Transactions help the database in satisfying all the ACID (Atomic, Consistent, Isolated, and Durable). Transaction processing is an indispensible part of ADO.NET. It guarantees that a block of statements will either be executed in its entirety or rolled back,( i.e., none of the statements will be executed). Transaction processing has improved a lot in ADO.NET 2.0. This article discusses how we can work with transactions in both ADO.NET 1.1 and 2.0 versions. #05-17 14:48
