Custom Report Item Class Libraries
새 설치: 2005년 12월 5일
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.
Custom Report Item Infrastructure Classes
The following classes are used to implement a custom report item.
[!참고] The following tables are not complete listings; they include only the most commonly used properties and methods for each class.
Microsoft.ReportDesigner.CustomReportItemDesigner
This is the main custom report item class. The main class of your custom report item implementation must inherit from this class.

The height of the custom report item control. |
Width |
The width of the custom report item control. |
Report |
A container for the report-level properties, such as the list of datasets in the report. |
AltReportItem |
The alternate report item object, to be used where the custom report item run-time control is not supported. |
Style |
The style properties for the custom report item. |
Adornment |
An adornment window used for interactive editing of the control. |
Site |
The ISite of the component. |
