Working with Computed Columns : Scott Mitchell
Sunday, July 06 2008
When creating a database table, Microsoft SQL Server allows you to define a computed column whose value is calculated from an expression that usually references other values in the same database record. Such values are read-only at the database, which requires special considerations when working with TableAdapters. In this tutorial we learn how to meet the challenges posed by computed columns. Microsoft SQL Server allows for computed columns, which are columns whose values are calculated from an expression that usually references the values from other columns in the same table. As an example, a...
Selecting CheckBoxes Inside TreeView Control : Azamsharp
Saturday, July 05 2008
In the last article I explained that how you can populate the TreeView control with the data coming from the database. You can read the new article at Populating TreeView Control With Database. In this article I will explain that how you can select checkboxes which are inside the TreeView control. The first task is to populate the TreeView control. I have authored a detailed article which focuses on how to populate the TreeView control using the database. I highly recommend that you check out the article, Populating TreeView Control With Database....Building TreeView Resultset with SQL Server 2005 : Ameet Phadnis
Friday, July 04 2008
This article is an upgrade of my previous article on Building Tree View Resultset. It explains how we can create the Tree View Resultset with SQL 2005 with just one SQL Statement. In a corporate environment we usually face coding tasks to display results in Treeview. The tasks may include displaying corporate structure or in programs displaying the menu structure. Around 5 to 6 years ago when I was tasked with a similar kind of assignment, my manager wanted me to get the results through the SQL Stored Procedure and then the web front end would do the rest. I came up with a way to create the tree...
Querying Data with the SqlDataSource Control : Scott Mitchell
Thursday, July 03 2008
In the preceding tutorials we used the ObjectDataSource control to fully separate the presentation layer from the Data Access layer. Starting with this tutorial, we learn how the SqlDataSource control can be used for simple applications that do not require such a strict separation of presentation and data access. All of the tutorials we’ve examined so far have used a tiered architecture consisting of presentation, Business Logic, and Data Access layers. The Data Access Layer (DAL) was crafted in the first tutorial (Creating a Data Access Layer) and the Business Logic Layer in the second ...
Caching Techniques in ASP.NET 2.0 : Richard Bean
Wednesday, July 02 2008
Performance is the key requirement of any application. One of important technique which helps in the performance of application is Caching. Caching is the process of storing frequently used data on the server to fulfill subsequent requests. Reusing pages from memory is much faster than re-creating pages every time they are requesting. Caching increases your application's performance, scalability and availability. In ASP.NET, caching is implemented as an HttpModule that listens to all HttpRequests that come through the ASP.NET worker process....Updating and Deleting Existing Binary Data : Scott Mitchell
Tuesday, July 01 2008
In earlier tutorials we saw how the GridView control makes it simple to edit and delete text data. In this tutorial we see how the GridView control also makes it possible to edit and delete binary data, whether that binary data is saved in the database or stored in the file system. Over the past three tutorials we’ve added quite a bit of functionality for working with binary data. We started by adding a BrochurePath column to the Categories table and updated the architecture accordingly. We also added Data Access Layer and Business Logic Layer methods to work with the Categories table’s...
New ASP.NET Dynamic Data Support : Scott Guthrie
Monday, June 30 2008
In this article, Scott examines how to build powerful data driven websites using the new Dynamic Data Support model in ASP.NET 3.5. Scott introduces a screen-cast followed by a series of steps with associated screenshots with emphasis on LINQ. Finally, Scott provides a complete analysis of the output along with a customization tip and a list of useful references. The ASP.NET 3.5 Extensions CTP we shipped this past weekend contains a bunch of great new features. One of the cool new features is something we call "ASP.NET Dynamic Data Support". In a nutshell this enables you to really quickly...
LINQ to SQL Instantiation : Brian Mains
Monday, June 30 2008
This article discusses how and when the objects within LINQ to SQL are created and instantiated, and how it maintains a list of the changes that need submitted to the database. It also discusses how this can be managed and some of the intricacies in LINQ with the help of source code. LINQ to SQL is an ORM tool that connects to SQL Server databases. It generates business objects to match a database's table structures, which are all centrally available through the DataContext class. The LINQ-to-SQL designer creates a custom DataContext class that contains a series of Table objects representing each...
Paging Database Results in ASP.NET : Scott Mitchell
Monday, June 30 2008
This article examines how to create a databound listbox using ASP.NET. For more information on ASP.NET be sure to check out the articles in the ASP.NET Article Index. The code in this article is based on the Beta 2 version of ASP.NET. To learn more about the free ASP.NET Beta 2, be sure to check out this FAQ. One of the most common tasks developers are faced with when working with data-driven Web sites is the need to page data. Most data is only worthwhile if it can easily be digested by a human, so a data-driven Web site needs to present data in an easy-to-read format. In situations where a large...
Inserting, Updating, and Deleting Data with the SqlDataSource : Scott Mitchell
Monday, June 30 2008
In previous tutorials we learned how the ObjectDataSource control allowed for inserting, updating, and deleting of data. The SqlDataSource control supports the same operations, but the approach is different, and this tutorial shows how to configure the SqlDataSource to insert, update, and delete data. As discussed in An Overview of Inserting, Updating, and Deleting, the GridView control provides built-in updating and deleting capabilities, while the DetailsView and FormView controls include inserting support along with editing and deleting functionality. These data modification capabilities can...
