Preparing to Implement a Delivery Extension

Before you implement your Reporting Services delivery extension, you should define the interfaces to implement. You first need to decide how your delivery extension will be used, what settings your delivery extension will require, and the specific functionality you will need to implement in order to deliver report notifications.

Each Reporting Services delivery extension must provide the following functionality:

  • An IExtension interface implementation that represents the extension and a localized extension name.

  • An IDeliveryExtension implementation that creates a delivery extension that can be used to deliver report notifications to end users.

  • The ability to process specific user data for a subscription.

Each delivery extension can be enhanced to include the following functionality:

  • An ASP.NET user control implementation that enables end users to use Report Manager to create report subscriptions that use the delivery extension.

The following table describes the available interfaces and classes for delivery extensions.

Interface or class

Description

IExtension Interface

Represents an extension in Reporting Services.

IDeliveryExtension Interface

IDeliveryReportServerInformation Interface

Report Class

Represents report-specific information and methods that enable delivery extensions to deliver reports to users.

ISubscriptionBaseUIUserControl Interface

A user control that represents the means to retrieve delivery extension-specific subscription information from the user in Report Manager (for example, an e-mail address or the path to a file share).
