Problems I dont need to show a empty detail section

[Jose Viana]

Hello,

I have a problem with my report.
I created a report with this sections (see "Structure.jpg" from attached files):

- groupHeaderSection (Student Group)
    - groupHeaderSection (Subject Group)
        - Detail
    - groupFooterSection (with property "visible = false")
- groupFooterSection (with property "visible = false")

My problem is, sometimes I havent values (becouse I get "null" from my database for all textboxes) in detail section, in this situation, I wouldn't like show this section becouse it's empty.
See preview.jpg in attached files.
Is there any property to hide the detail section when it contain empty textboxes?

Thank you,

Regards,
Jose Viana.
