Attachment 93173

When I am using a List on my report my layout get messy when running application and if the List has value on it.
All other item's padding are set to Zero, but that big space still appearing.

Any suggestions what to use? Instead of List.
I tried to use textbox but it appears only the first record of my Dataset.

Bump.

I tried to play around but still I could not achieve what i want. Still those spaces are there.

Resolve by using rectangle
I put all group textboxes inside a rectangle.
