Hi,
I can't describe my disappoinment.
This is so bad for us not having a group by ability in virtual mode.
All our grids-trees are virtual binded, and group-by is a must in all of our project, and I always kept telling eveyone there is no problem with that feature.
Can't you even let us pre-set the group by before we start the binding, without supporting gorup-by change in runtime (without re-initialize the whole grid)?
please re-consider adding this feature, even only in the next major verion, because this is so important to us.
thanks!
