I've found the solution ....
I've created a class which implements ICellEventHandler and applied it
to the specific cell in my rptdesign :
For example :
public class CellImpl implements ICellEventHandler {
public void onCreate(ICellInstance arg0, IReportContext arg1) {
try {
Object data = arg0.getData();
if (data != null) {
if ("".equals(data.toString().trim())) {
arg0.getStyle().setBackgroundColor("yellow");
}
}
} catch (Exception e) {
// TODO: handle exception
}
}
public void onPrepare(ICell arg0, IReportContext arg1) {}
public void onRender(ICellInstance arg0, IReportContext arg1) {}
}
Best regards
Dov
