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.

I have a big issue with birt report recently. We all know that we can use birt report designer to draw a report by drag some report elements from palette. But,my leader have a point that if we can draw a simple report without using birt report designer?
You can use Excel as a data source and then use the API to pull information out of that or build a report. As mentioned earlier, you can also create the XML that defines the report outside of the designer as well. You could also write JavaScript or other client side code to take the Excel file and extract data from that to use in a report.
I wanted to generate report using huge data load. when I'm generating a report using Birt it would load the all data and Birt report viewer will do the pagination for me. It seems like a huge performance draw back and it has been taking so long to process the report.
So I though of putting a limit queries on my scripted data source to load only the data that required to show on the current page. And My birt report viewer also should show proper pagination arrows to navigate through the report pages. and it will generate pages on demand.
I would thing anybody might have implemented this before. please help me on this.
Thanks

Using BIRT 4.2
My database (Postgresql) has many fields with hyperlinks in it and when I am displaying the reports via BIRT report viewer, all the fields which have hyperlinks are displayed as normal text in the BIRT report viewer. I want the hyperlinks to be retained at the BIRT report viewer. How can I achieve this. Please suggest.
Select the corresponding cell and go to the hyperlink property and click on edit and select the URI radio button and click on the javascript syntax button and you will find your column bindings from that select the value of the column and finally you will get the hyperlinks
your url should be like this (http://www.+row["Title"]+.com) if your Title field having google means then your string should be like this ("http://www.google.com").if you didn't append any HTTP means then it will look for the file which is in webcontent folder of your birt.war
How do I make a common masterpage in BIRT? I'd like all of my reports to use a common master page, so that I can make a change in one place and all of the reports that use that master page automatically get the change.
Create a masterpage in a BIRT library and then have all of your reports use that masterpage. Here's how:
Open the BIRT report designer
File -> New -> New Library
In the Outline pane expand Masterpages. Rename the masterpage to something meaningful - you'll want to do this in case you create multiple masterpages in the future. For example, you may want one masterpage for Portait reports and a different one for Landscape reports.
Save
Open a report which you want to link to the common masterpage
In the Resource Explorer pane expand Shared Resources -> your newly created library -> MasterPages
Right click on your masterpage -> Add to Report
Delete the old masterpage in the report
Your report will then be linked to a common masterpage - if you change something in the masterpage, the report will automatically get that change. You won't have to change the individual report.
As an addition to jrullmann's answer:
Usually, the masterpage should contain some dynamic data, such as the title of the report, and in some cases part of this data resides inside the DB.
To achieve this, you can for example create a Data Set "Masterpage" which resides in the same *.rptlibrary as the masterpage.
The DS query has the form
select ? as title,
...
from DUAL
and has parameters like title, ... .
Bind the header and footer grid of the masterpage to this DS.
Then, in your report, reference the master page and change the DS parameter binding in the header and footer grid.
When looking for examples of custom BIRT report items, there are a few versions of RotatedText/RotatedLabel around, and DotBar (only in BIRT Controls Library). Any others?
