I am using IReportEngine to open a template report and IReportRunnable to created the elements of the report. Then IRunAndRenderTask to display the report and return it as HTML. what I don't know is how to add the Birt toolbar and the navigation bar to the generated report. Any idea or suggestion ?
Both toolbar and pagination are components of the webviewer, not components of the BIRT engine API. If reports are generated with the report engine API, as far a i know there is no way to display these elements out-of-the-box: you need to implement your own toolbar and pagination widget.
