Hi,

What is the best approach to provide Row Aggregation functionality in ArrayCtrl?

Suppose I have five rows (ignore ... - didn't know how to embed a space):

A B C
> 1 2 3
...1 5 6
> 2 3 5
...2 3 7
...2 3 2

I want to be able to click on some TreeCtrl-like arrow > and collapse the results into some aggregation after two clicks.

A B C
^ 1 7 9
^ 2 3 14

Rows A=1 has summed columns B and C (Aggregate by A)
Rows A=2, B=3 has summed column C (Aggregate by A,B)

This kind of functionality probably adds a lot of complexity to a class so if someone can suggest an approach (which methods should I focus on?) to how I would best implement this in an extended class, I would greatly appreciate it - or if someone has an example, that would even be better!

Thank you.

Regards,
Ken
