Make whole "Group" invisible

Hi guys,

I have Group (this group contains two elements: Caption and Table) in my TransparentContainer and I want to make it invisible. I've created new node in Context with Attribute of "WDUI_VISIBILITY" type and bound it to Visible parameter of my Group.

Can you provide some code to make whole group invisible or if it is not possible aby other way to make elements of Group invisible?

Thanks in advance
