In this tutorial you will learn about Complex Data Binding, Binding to a ComboBox or ListBox, Binding to a DataGrid. Complex data binding is the ability of a control to bind to more than one data element, typically more than one record in a database, or to more than one of any other type of bindable data elements.
Recently, I had a requirement to put together a website that deals with taking somewhat elaborate financial surveys. While the questions and answers themselves are good candidates for being database driven, there were a large number of nuiances ranging from UI items, business rules, and calculations that just didn't fit into a database driven strategy. With this in mind, my initial strategy was to create version specific classes and reference them in version specific ASP.NET pages. Of course, this accomplished the initial requirement. However, whenever a new version needs to be implemented, I had to copy all of the ASP.NET pages and modify the references to the appropriate version specific class name. Refactoring provides a better alternative and here's how:
ASP.NET is built on a core set of classes and interfaces that abstract the HTTP protocol. The three core abstractions are the context (HttpContext) that represents the current HTTP request, handlers (classes that implement IHttpHandler) that are capable of servicing HTTP requests, and modules (classes that implement IHttpModule) that can pre/post process HTTP requests to provide additional services.
The objective of this lab is to convert a simple JSP application into an ASP.NET application using the Java Language Conversion Assistant (JLCA). The JSP application is a simplified e-commerce scenario, consisting of two JSP pages, a Servlet, a tag library consisting of a single tag, and the SQL Server Pubs database.
Learn how to use the tools and options in Visual Studio .NET to increase your productivity and work efficiently in a team environment when building ASP.NET applications.
In this paper, we discuss the benefits that companies are seeking to gain in migrating to ASP.NET, and the various approaches they can adopt. We also discuss how to estimate the complexity of a .NET migration, and outline the main phases of a well-planned migration.
RSS (Rich Site Summary) news feeds are easily consumed and displayed in an ASP.NET web forms page using no more than a few lines of codes. However, listing the RSS news feed links in this fashion can take up considerable page space. Instead, it would be more convenient to display them in a small embedded window that automatically scrolls them to the user. This method substantially reduces the page real estate devoted to the news feed, while displaying the same information in a compact, attractive, and intuitive manner. Once you have developed a method for displaying RSS news in this format, it would be still more convenient to implement the method as a custom control that you can add to any ASP.NET web forms page with just a few lines of code. This article shows you how.
In this article, you will learn how to create the illusion of continuous seamless scrolling by: 1) using two datagrids to display the same listing; and 2) scrolling the entire total list, but then repeating the scrolling when it has passed over the first list.

VB.NET 2005 Free Training : Event Handling In Visual Basic .NET 2005 - Introduction to Event Handling, One of the most useful capabilities of the OOP Languages is their inbuilt ability to be aware of a large number of events like MouseOver, MouseClick, and so on so that we can write codes to react to any event that we are interested. This is made possible by the rich set of classes that have been built in the .NET Framework.
