Visibility Problem (How to supress a row having parameter value)

sanjaym

I have 10 parameters in my report.

Report output types are html and pdf.

The parameters values are displayed at the end of the report in a grid. The grid has 10 rows, each row having a parameter.

If a parameter value is not entered i.e. left blank then that grid row should be supressed.

How do I supress a Grid row in my report.

I would highly appreciate if you could mention the steps as I am new to BIRT.

Thanks
Sanjay

1) Open your report design in layout editor
2) Select the row that you want to hide
3) In Property Editor, select Visibility , check Hide Element checkbox
4) Click on Fx button which is beside Expression field
5) Select Report Parameters from Category list
6) Select All from Sub Category List
7) You will see all the defined parameters in the 3rd list box.
8) In the expression text area, have something like

if(params["param1"]==null || params["NewParameter"].value=="")
{
true
}
else
{
false
}

Note: param1 is the name of the parameter in the subject.

Hope this helps.
