Thank you for your time, I really appreciate your help.
I have used your sample, with the 2 attached files, also I have made a video.
Unfortunately the result is still the same.
We are using SyncFusion 7.4.0.20 in our project, do you think it is necessary to upgrade our version to the latest?
Just to make sure, I have checked the exe-Video with Kaspersky AntiVirus, so there won't be any harm.
best regards, Stefan
