Is it possible for you to open a new support thread with a sample attached where the issue is reproducible. We are not aware of such existing problems in the RadUpload so we think this is the best way to proceed. Thank you for your cooperation in advance.
There is no limitation in the number of handlers that can be used. What is the error that you encountered? Could you please elaborate more on your scenario ? Thank you in advance.
All the best,
the Telerik team
