Hi Keita,
Greetings
from Syncfusion support
From your
provided information, it appears you are experiencing a misalignment issue with
the Frozen column when the validation message displays in the last row. To
address this, we have created a sample and attempted to reproduce the issue;
however, the validation message displayed correctly without any misalignment.
Please refer to the sample and screenshot below for more details.
Sample: Check
the attachment.

We suspect
that you are using an older Syncfusion package version, and it was the cause of
the problem. So, we recommend upgrading your NuGet package to the latest
version 27.1.57 and define the latest CDN link in the _Layout.cshtml
file, to resolve the problem. Please refer the below screenshot for more
information.


If still you
are facing problem, kindly share the below details
1) Share your NuGet package version.
2) Share your complete Grid rendering
code, we would like to check your Grid initialization and the features you have
utilized.
3) Share any issue reproducible sample
or try to reproduce the issue with our above attached sample.
Regards,
Rajapandi R
