What are the differences between the two base classes and what are the inherit benefits of using one over another?

Posted By :Deco     Posted Date :October 27, 2010    Points :10   Category :SharePoint 
The difference is the Microsoft.SharePoint.WebPartPages.WebPart base class is meant for backward compatibility with previous versions of SharePoint. The benefit of using the SharePoint WebPart base class is it supported: Cross page connections Connections between Web Parts that are outside of a Web Part zone Client-side connections (Web Part Page Services Component) Data caching infrastructure ASP.NET 2.0 WebParts are generally considered better to use because SharePoint is built upon the ASP.NET 2.0 web architecture. Inheriting from the ASP.NET 2.0 base class offers you features that inherit to ASP.NET 2.0, such as embedding resources as opposed to use ClassResources for deployment of said types.

What are the two base classes a WebPart you are going to use within SharePoint 2007 can inherit from?

  
There are two base classes that a WebPart which is going to be consumed by SharePoint can inherit from, either the
SharePoint WebPart Base class
or the
ASP.NET 2.0 WebPart base class.
When inheriting from the SharePoint WebPart Base class your derived WebPart class will inherit from Microsoft.SharePoint.WebPartPages.WebPart. When inheriting from the ASP.NET 2.0 WebPart base class your derived WebPart class will inherit from System.Web.UI.WebControls.WebParts.WebPart. It is considered good practice to use the ASP.NET WebPart base class since the old base class is meant for backwards compatibility with previous version of SharePoint, however there are four exception when it is better to leverage functionality from the SharePoint WebPart base class:
Cross page connections
Connections between Web Parts that are outside of a Web Part zone
Client-side connections (Web Part Page Services Component)
Data caching infrastructure

What are the base classes, event handlers can inherit.

  
While developing event handlers there are several base classes from which you can inherit.

SPItemEventReciever: One must inherit from this base class if you want the event handler to be executed when the item is added,updated and deleted.

SPListEventReciever: One must inherit from this base class when you want the event handler to execute when the structure of the list is modifed or the content type added or removed from the list.

SPFeatureEventReciever: Inherit this base class if you want your event handler to execute when the feature events such as installation,unstallation,activation and deactivation are executed.

SPWebEventReciever: You can Inherit this base class if you want your event handlers to execute when site is added or removed from the site collection.

SPEmailEventReciever:Inherit this base class for creating a event handler for emails that are send to a Sharepoint list.
