Custom report items use classes from the Microsoft.ReportDesigner namespace. The classes used to implement a custom report item can be grouped into two main categories: unique classes designed to support custom report item infrastructure, and managed wrapper classes that encapsulate the functionality of relevant Report Definition Language (RDL) elements. For a code sample on how to use these classes, see SQL Server Reporting Services Product Samples.
The following classes are used to implement a custom report item.
Note
The following tables are not complete listings; they include only the most commonly used properties and methods for each class.
