Grid column locking is a great feature. But it's also very frustrating.
I use column locking together with summary, cell editing and header grouping. And it destroys my grid.
The summary and last row are missing, the scroll is not synchronous.
Once I remove the column locking, the grid works fine.
This problem has not yet been solved. Even in the latest release (4.1.1).
It's also very hard to debug.
I think there is a big mistake in the designing step. I do hope that it will be solved soon.
Thank you very much.
