Hi Telerik,

Below is my code.  Before I add OnclientvalidationFailed event and specify MaxFileSize, everything works fine.  However, after I added this event, the code in my onclientfileuploaded does not function well.

What happened was -
(1), (3), (5) are still on the list, while I am expecting only (1), (3) on the list.

Steps to reproduce an error -
(1) upload a good file - e.g. Doc1
(2) upload a file which is more than 2 mb
(3) upload a different good file - e.g. doc2
(4) upload a too large file
(5) upload (1)'s file

This is very urget.  Please kindly help.

Thanks!

Joan

Hello Joan,

 
It seems that when deleting files at particular position you are getting the uploaded files minus one which deletes the forth file instead of the fifth one. I will recommend you to use sender.deleteFileInputAt(numberOfFiles) instead of sender.deleteFileInputAt(numberOfFiles - 1).

Hope this will be helpful.
