Inline Editing throws Exception on Console

[Zhi Yuan]

To replicate the error as stated in the Subject:

1. Use the code as-is from https://blazor.syncfusion.com/documentation/datagrid/editing/#normal

2. Double click on the first row, on the column "Customer Name". You should enter into Edit mode.

3. Open up Devtools and observe the following error message in the Console: Uncaught (in promise) Error: System.ArgumentException: There is no event handler associated with this event. EventId: '400'. (Parameter 'eventHandlerId').

I have attached the video showing how to replicate this issue.

Tested on .NET 5 RC 2, Syncfusion 18.3.35 & 18.3.44.

Hi Zhi, 

Greetings from Syncfusion. 

Query: Inline Editing throws Exception on Console 

We have validated the reported issue and it occur due to @onblur event of Blazor for elements inside the EditForm. Inside the GridEdit Form (inline editing), we have used the textbox controls and other editor controls. They have used @onblur event for certain actions. It is not related to Syncfusion components alone, it is a Framework issue.   

  

Please find the below Github issue which is reported by Blazor team. Once below issue resolved, this error will not be thrown.

Also above error will not affect the default functionality of Grid Editing. Please get back to us if you have further queries.

Hi Rahul,

Thanks for your prompt response!

> Once below issue resolved, this error will not be thrown.  

The issue that you've linked to has already been closed and it's tagged to NET 5 RC1 milestone, so that issue should have been already resolved though. Or am I seeing it wrongly?
