Hi Ibrahim, 

We are facing dependency issues when try running your shared application. So, we have analyzed the codes you have used in the shared application. We suspect that the reported problem occurred because of having the CreatedBy column in Grid. As the type for CreatedBy is a class ApplicationUser, we suspect that this is a complex typed column which you have bound in Grid. 

To bind complex typed data to Grid, it is recommended to follow the below documentation, 

https://blazor.syncfusion.com/documentation/datagrid/columns/#complex-data-binding 

So please use the above way to bind complex typed data in Grid. And if you are still facing difficulties or if we have misunderstood the scenario, then kindly share with us the details to proceed further. 

1. Please check this case by removing CreatedBy column and try reproducing the exception on editing.
2. Share with us a video demo showing the types of data you will be binding in Grid.

And also please bind the “OnActionFailure” event to Grid. This event will be triggered for every failure in Grid. Please share the details you get in the “args” of this event handler for further analysis.
