IndexOutOfRangeException when data changed in underlying DataTable

[Liu Yang]

Hi,

From the call stack below, the exception comes from Syncfusion.Grouping. Unfortunately the issue cannot be reproduced easily, it only happened once.

I am not sure if this is a problem of syncfusion library or some bug in my code(probably threading issue).

I am using an old version of syncfusion grid (6.102.0.34).

Any help is much appreciated.

Thanks
Jimmy

Hi Jimmy,

Thank you for your interest in Syncfusion products.

Hi Asarudheen

Unfortunately I couldn't reproduce the issue with a sample project. The exception happens randomly, I guess it's due to frequent data updates for the bounded DataTable.

May I know where changedFieldsArray is getting cleared?

changedFieldsArray is in Syncfusion.Grouping.Table

cheers
Jimmy

ChangedFieldArray is an ArrayList

I googled that the exception will happen when TrimToSize() and Add() are called on separate threads.

Hi Liu ,

Thanks for the update.

It is hard to trace why this issue is arising without seeing the sample. We have searched our support database for any such similar issues, and found no similar issues found.
