Report Item

kosta · August 23, 2010

Hello BIRT community,

How can I pass value to my custom report item (as String or Integer) from some data source (DB, File).

Should the value be read over item property or directly into the custom report item or is there any other solution about this?

Many thanks.

Kosta,

If your report item is nested in a grid or table you should be getting passed the rows in the onRowSets method of your implementation of the IReportItemGeneration and IReportItemPresentation interfaces.

Hallo Jason,

I want to connect the report item with the datasource.
From the example that I am using I can pass the data with the IReportItemPresentation interface.
But those data are static and added manually in the designer view.

Instead of that I want to connect some datasource to the item.
I don't know if I can do that with the designer or I need to implement it programmatically.

The example what I am using can be found on:
http://www.eclipse.org/articles/article.php?file=Article-BIRT-ExtensionTutorial1/index.html

The data should be readed somehow by the modelHandle in the "class RotatedTextItem extends ReportItem"
That means the modelHandle already has the data from some datasource.

Maybe I miss simple understanding about binding items to external datasources.

Thank you.

Hello BIRT community,

my question is, how can I see the Binding Tab in the property view of my custom item.
That's something that I am missing in the view.

My custom item is based on the "Rotate Text" Example.
The custom item of the first example (BIRT Extension Mechanism, Part 1: Custom Report Items) don't have properties at all. The Tab is empty.
The custom item of second example (BIRT Extension Mechanism : Part 2) only have the properties- and the custom-tab but not the "Binding"-tab.

What can I do, so the "Binding"-tab is shown or how can I bind data sources to the custom report item?

Thanks.

kosta, 
 
Please refer to the new page generator implementation I've attached. This is a much cleaner version than the original one, but requires BIRT 2.5 or above. Actually this should be in Part 3 of the tutorial series, but not ready yet.:)

Hello Mr. Zhiqiang Qian,

now I can see the "Binding"-Tab!

I notice that the RotatedTextPageGenerator extend BasePageGenerator instead of the AbstractPageGenerator.

Thank you very much.
I will test now the new functionality.

Thank you all.
Cheers.

If the version of the page generator is still available can you repost? Thanks!

Hello Nicholasr,
 
as far as I can remenber ist was about one class which Zhiqiang Qian sent to me. I have then excanged the content. I think it was the extension of the BasePageGenerator.
