The rows are added by using the TableRow control and the cells are added by using the TableCell control.The Table, TableRow, and TableCell controls all inherit from the WebControl class.If you simply needed to add static rows and cells, it would be more efficient to simply use an HTML table.

Asp.net Site Navigatios

Introduction to Site Navigation Seamless navigation from one webpage to another is what makes a collection of webpages feel like a web application.Developers must consider when and how to move a user between pages.

However, with controls such as the Wizard control and technologies such as Asynchronous JavaScript and XML (AJAX), you can embed a lot of functionality inside a single actual page in … Read entire article »

Asp.net Server Controls

Server Controls Web server controls are based on .NET Framework classes, typically inherited from the WebControl class.A web server control is able to provide more functionality than an HTML control because it is not tied to a single HTML tag element. Instead, web server controls typically render many HTML tags and might also include client-side JavaScript code. They also have the ability to detect the web browser’s capabilities and render the appropriate HTML based on those capabilities. This allows ASP.NET web server controls to use a specific browser to its fullest potential. The programmer is also relieved from dealing with the actual HTML and instead works with the web server control to define the appropriate functionality … Read entire article »

MVC 2 Architecture

The Microsoft ASP.NET model-view-controller (MVC) represents an alternative architecture to the standard ASP.NET web form model.This alternative is based on the common MVC software design pattern that separates the layers of your website into user interface (view), data and business logic (model), and input handling (controller). This separation through MVC results in loosely coupled objects that are highly testable, can be developed independently from one another, and offer granular control of your application code. The model that uses postback and ViewState is nonexistent with ASP.NET MVC. Instead, MVC uses a routing engine and a set of controllers that provide you with deeper control over your processing and output.however, a few familiar items that are preserved in … Read entire article »
