Controlling Changes to Content Types

        You can prevent users from making changes to content types in two ways: specify a content
        type as read-only or define it as sealed.

WSS List limits

Performance with large lists and document libraries has also been another concern with Windows SharePoint Services 2.0. For example, lists often start showing degraded performance when the number of items exceeds 2000. Document libraries have similar performance concerns. However, the rule of thumb for not exceeding 2000 documents applies to each folder within a document library as opposed to the document library itself. Therefore, coming up with a scheme to partition documents across multiple folders within a document library has come to be a popular approach in Windows SharePoint Services 2.0 for dealing with a large number of documents.

wss and asp.net 2.0

Windows SharePoint Services 3.0 provisioning starts at the level of the IIS Web site. Before you can create your first Windows SharePoint Services site, someone must run an administrative procedure to extend 3.0 functionality onto one or more IIS Web sites. In Windows Share- Point Services 2.0, the term virtual server was used to describe an IIS Web site that had been extended with Windows SharePoint Services functionality. To avoid confusion with another Microsoft product of the same name, the Windows SharePoint Services 3.0 documentation now refers to an IIS Web site extended with Windows SharePoint Services functionality as a Web application.

Object DataSource Update

Assume you create a grid that shows a list of EmployeeDetails objects. You also add a column with edit links. When the user commits an edit, the GridView fills the ObjectDataSource.UpdateParameters collection with one parameter for each property of the EmployeeDetails class, including EmployeeID, FirstName, LastName, and TitleOfCourtesy. Then, the ObjectDataSource searches for a method named UpdateEmployee() in the EmployeeDB class. This method must have the same parameters, with the same names. That means this method is a match:

Parameterized Constructor of ObjectDataSource

Some time if the ObjectDataSource need a parameter instructor you can supply it in the ObjectCreating event.
