Introduction to Web Parts in ASP.NET 2.0

Summary

Webparts provide us with an easy way to customize our website on runtime. Aside from their availability in Sharepoint portal server, webparts were introduced in asp.net 2.0. I have tried to cover all the common aspects of webparts in this article, like using different types of webparts and using a custom database.

Introduction

It would not be wrong to say that web parts are going to be the future of web based management systems. Web parts give us the option to drag and drop objects on a page, change titles, border style, and properties of objects at runtime. Before the introduction of web parts it used to be a hectic task because we had to write a lot of java script and to save the state of contents in a database.

There are two basic things in web parts:

  • Web part manager.
  • Web part zones.

Web Part Manager

Web part manager is a manager for web parts behind the scenes. We normally don't do a lot of things with the web part manager either in code or in design mode.

Web Part Zones

There are four kind of zones in web parts

  • Web Part Zone
  • Editor Zone
  • Catalog Zone
  • Connection Zone

Web Part Zone:

It's a basic unit of web parts. By placing different contents in a web part zone we can allow a user to drag and drop contents on a page.

To use different zones place a dropdownlist and add following items in it.

  1. Browse
  2. Display
  3. Edit
  4. Catalog
  5. Connect

Write down following code on onChangeIndex event of this dropdownlist.

MVC Architecture Model In ASP.NET

Image
When developing ASP.NET applications the need of reducing code duplication increases along with their complexity. This is because testing and performing changes become very difficult tasks when having many different sources of code with the same functionality. Model View Controller architecture (or pattern) allows us to separate different parts of our applications into tiers to fulfill this need. MVC Overview Model View Controller architecture aims to separate an application into three parts: Model:  It is the business logic of an application. From an object oriented perspective it would consist of a set of classes that implement the critical functionality of an application from a business point of view. View:  It can consist of every type of interface given to the user. In ASP.NET the view is the set of web pages presented by a web application. Controller:  This part of the architecture is the most difficult to explain, hence the most difficult to implement in ...
