You can add interactive actions that allow users to open Web pages or other reports, jump to another location within the same report or drilldown to detail data. To add an interactive action, you define an Action on a report item. Use the Edit Action dialog to set the type of interactive action. When the user clicks that report item, the action that you define takes place. The report engine supports the following action types:
Navigate to Report : Jump to other reports from the main report (Drillthrough report).
Navigate to Bookmark : Jump to areas within a report.
Navigate to Url : Jump to external web URLs that specify the address of web pages.
Toggle Visibility : Show or hide report items within the same report.
Sorting : Apply sorting on report items like Table , Crosstab or Graph.
Custom : An action that contains collection of parameters that are evaluated during report processing.
The actions are feature of the report viewers and not of the rendering extension. You can find more info about the supported interactive features in each format by checking the Interactivity section of the respective articles in Design Considerations for Report Rendering Overview help section.
