Hi Mark,
Sorry for the inconvenience caused. We have tested the reported issue in different scenario but we are unable to reproduce the issue. Could you please check the below sample and Video?
Sample: GridDataControlRowHeight.zip
Video: VideoRowHeight.zip
We suspect you are using our grid in some other scenario, So If possible could you please modify our sample and revert us with replication procedure, that would be very helpful to resolve your problem earlier.
Please let know if you have any queries.
Thanks,
Rajasekar
