Hello Danglei,

I am not absolutely sure that we are talking for the same issue, or at least we are not able to confirm it with the stack trace. We can confirm that the original issue that was reported previously was fixed.

Can you please give me more details about your scenario, also I will appreciate if you send me sample application where I will be able to reproduce this issue and confirm when is fixed.   

Thank you.

Hi,

We've been seeing similar issues with almost exactly the same stack trace. So we've upgraded to the latest service release which went out late last month however it did not really help much.

One interesting thing to note is that before the update (10.2.2001) we were seeing the exception on ItemRemoved events (the index was perfectly ok, like #200 among a list of 2000 items), and now after the update (10.2.2045) we're seeing the exception now randomly thrown on ItemUpdated events (again index was ok too).

Usecase is very similar and the stacktrace is almost identical. These can be found below and I've masked some of the lines to hide some private code. Should you need them I can provide them to you email/private message, for which I believe there's a NDA between Infragistics and us.

Thanks for your help in advance!

Hello Ahmed,

I have created support case for you CAS-47759-TSMBMJ, so I will appreciate if you send me any other information, code snipped, samples that will help me to reproduce and investigate this issue.

Thank you.

Dimi,

The UI doesn't directly delete records ... As I mentioned before, the grid is connected to pub/sub system which updates the iBindingList which is attached to the grid. In this instance the publisher issued a delete row instruction to delete a record which has 3 chid records. The publisher normally removes children before deleting the parent. In this instance an exception was thrown when it attempted to delete the first child. This is currently captured in VS debugger and I have a full Stack Trace and a DataRecord snapshot which shows dataRecordIndex = -1, the rest of the properties in the DataRecords are correctly populated.

To answer your other questions, the application is mult-threaded but we have not dectected any race conditions in the publisher. Each user/client connects seperately publisher and has seperate instance of the data set, so I wouldn't worry too much about synchronising with other users

I'm not sure how to attach this information (stack trace and Datarecord snapshot). Can you please get in touch with me directly and I'll share the logs. We're also trying to contact the account manager to see if we can arrange your team to debug online as its impossible to create a sample project.
