DropDownList Inside The GridView Method 2 : AzamSharp
Sunday, September 28 2008
This is the second installment of the article, DropDownList Inside the GridView. In the previous article DropDownList Inside the GridView I talked about how you can populate the DropDownList inside the GridView with different data using a DataSet. In this article I will demonstrate that how you can achieve the same behavior using Entity Classes...Friendly URLs with URL mappings : Marco Bellinaso
Thursday, September 25 2008
This sample extract from the Wrox's book "ASP.NET 2.0 Website Programming" shows how to set-up the new url-mapping feature built-into the ASP.NET 2.0 framework. You no longer need to manually code a custom HttpModule! The more meaningful and short a URL can be, the better. Those URLs are easier to communicate to people, and easier for them to remember. The current URLs that allow us to browse articles for a specific category are already pretty short, but it’s not easy to remember all category IDs by heart . . . and thus to remember the URL. ASP.NET 2.0 introduces a new section in web.config that...
Accessing data using Language Integrated Query (LINQ) in ASP.NET WebPages – Part 1 : Balamurali Balaji
Wednesday, September 24 2008
This article comprises of two parts; Part 1 deals with the introduction to LINQ and LinqDataSource control in ASP.NET and describes how to define and retrieve an in-memory data collection and display data in a web page. Part 2 explains how to create entity classes to represent SQL Server database and tables using Object Relational Designer and display data in a web page using LinqDataSource control. Language Integrated Query (LINQ) is a query syntax that defines a set of query operators that allow traversal, filter, and projection operations to be expressed in a declarative way in any .NET-based...
Using Parameterized Queries with the SqlDataSource : Scott Mitchell
Monday, September 22 2008
In the previous tutorial we saw how to use the SqlDataSource control to retrieve data directly from a database. Using the Configure Data Source wizard, we could choose the database and then either: pick the columns to return from a table or view; enter a custom SQL statement; or use a stored procedure. Whether selecting columns from a table or view or entering a custom SQL statement, the SqlDataSource control’s SelectCommand property is assigned the resulting ad-hoc SQL SELECT statement and it is this SELECT statement that is executed when the SqlDataSource’s Select() method is invoked (either...
Entity Framework and Lazy Loading : Timothy Khouri
Sunday, September 21 2008
Microsoft's Entity Framework is a new, powerful tool bringing data modeling, O/RM (object relational mapping) functionality and more. One expected feature of major ORMs is 'Lazy Loading'. Learn how the Entity Framework provides this functionality in a different way. This article will explain the design reasons behind why EF is different than what you would expect, as well as how to achieve the lazy-load functionality you're looking for. It is important to realize that that ORMs are not a new concept. There are a lot of excellent ORMs out there for Ruby, Python and even for the .Net framework (NHibernate...

Thursday, September 18 2008
A common web site requirement is the ability to share certain files with specific users. For example, customers who have purchased software or other digital assets from a web site should ideally be able to return to that site and re-download the file(s) any time they want. However, that user (and other users) must be prevented from downloading packages that they have not purchased. This article will not attempt to cover ASP.NET user authentication techniques since that topic is already thoroughly covered elsewhere. Instead this article will focus on how (and how not) to provide access to a file...
Formatting the DataList and Repeater Based Upon Data : Scott Mitchell
Wednesday, September 17 2008
As we saw in the preceding tutorial, the DataList offers a number of style-related properties that affect its appearance. In particular, we saw how to assign default CSS classes to the DataList’s HeaderStyle, ItemStyle, AlternatingItemStyle, and SelectedItemStyle properties. In addition to these four properties, the DataList includes a number of other style-related properties, such as Font, ForeColor, BackColor, and BorderWidth, to name a few. The Repeater control does not contain any style-related properties. Any such style settings must be made directly within the markup in the Repeater’s templates...
How to Popup a Window Using DIV Layer in ASP.NET 1.x/2.x : Bilal Haidar
Tuesday, September 16 2008
In a project I am currently working on (ASP.NET 1.1), one of the Web Forms included has a set of three controls that represent a certain feature in the system. Suppose those controls are simple DropDownLists. When a value is being selected in the first DropDownList, the data present in the second DropDownList should be filtered by the first value selected. The same idea applies on the third DropDownList. This form is going to be used by end users who know nothing about ASP.NET or about development in general. All they want is a fancy web form that makes their life easy. A decision has to be made...
