Hi Eric,
Greetings
from Syncfusion support.
We have
analyzed your shared codes and we could see that you have not defined IsPrimaryKey
to true for any of the unique valued column in grid. It is a must to define the
IsPrimaryKey to a unique valued column to perform CRUD
operations in Grid .
Reference
: https://blazor.syncfusion.com/documentation/datagrid/editing
So we
suggest you to ensure to set IsPrimaryKey for any of the unique valued
column in grid to overcome the reported scenario. Please check this from your
side and get back to us with details if you are still facing difficulties.
Regards,
Renjith R
