Cutting Edge - Custom Script Callbacks in ASP.NET
Tue, 14 Dec 2004 10:00:00 GMT
ASP. NET client callbacks represent a neat and elegant way to execute server-side code without posting and refreshing the current page.I discussed ASP. NET callbacks in the August and December 2004 installments of Cutting Edge, considering them from the perspective of rendered pages making background callbacks to the server, sending input data to the relevant page, and receiving a response.

GridView - Move Over DataGrid, There's a New Grid in Town!
Tue, 20 Jul 2004 10:00:00 GMT
When incorporating the ASP.NET DataGrid control into your Web apps, common operations such as paging, sorting, editing, and deleting data require more effort than you might like to expend. But all that is about to change. The GridView control--the successor to the DataGrid-- extends the DataGrid's functionality it in a number of ways. First, it fully supports data source components and can automatically handle data operations, such as paging, sorting, and editing, as long as its bound data source object supports these capabilities. In addition, the GridView control offers some functional improvements over the DataGrid. Here DataGrid expert Dino Esposito introduces the GridView and explains all its long-awaited features.
Cutting Edge - Script Callbacks in ASP.NET
Tue, 20 Jul 2004 10:00:00 GMT
If you're involved in Web development you may have faced a problem that you couldn't find a good solution for—making client-to-server calls outside the current page.For example, you might want to validate the content of a textbox against data stored on the server asynchronously, without interrupting the continuity of the work or without forcing a full page refresh, which is particularly heavy for UI-rich pages.
Cutting Edge - Implement Custom Cache Dependencies in ASP.NET 1.x
Tue, 15 Jun 2004 10:00:00 GMT
One of the most compelling improvements that ASP. NET brought to ASP programming was the Cache object.The Cache has some similarities to the Application object and is a container of global data (as opposed to session-specific data) that features a fair number of innovative characteristics.
Data - More Load, Less Code with the Data Enhancements of ASP.NET 2.0
Tue, 18 May 2004 10:00:00 GMT
A data source control is a server control that wraps some basic functions of a data source - be it a SQL Server database, an XML document, an Excel worksheet, or a sitemap description. Through the services of a similar component, data-bound controls can fetch data as well as insert new records or update and delete existing ones. Data source controls enable a consistent model across a variety of data sources and dramatically reduce the amount of code needed to implement a two-way data-binding scenario. This article provides an introduction to data source controls and other related data binding features.
