Grouping container, is there any limitation?

hi guys,

I was wondering about a silly thing but, anyway, which is the maximum number of grouping for a container? I mean, when you group from, i.e, a sql task and then over that group do again another one and so on...

Thanks in advance for your time,

Don't quote me on this, but I'm assuming that a container just has a container for children effectively creating a linked list. So the limit should be memory or the level that .Net would allow say For loops to be nested.|||thanks a lot
