Hi.. I'm having huge problems when using a custom engine to modify the grid grouping control's appearance.
It all works rather well until I expand the nested table and move my mouse over it or try to scroll. At that moment I get an exception that I just can't figure out. It has something with record count.
I've tried implementing every single GetCount method - basically I invoke the base.GetCount() (visible, record, filtered.. whatever) but the exception is always the same. But whether I do it or not nothing changes.
I've attached the stack trace so maybe you could figure it out.
Please help me - I'm starting to freak out here.
