Thank you for elaborating on this issue. I have reproduced it and logged it for further research. As a token of gratitude I have updated your Telerik points.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?

any news on that issue? I have spent a full day trying to find a bug in my programming until I came across this thread. Is there any workaround so the events don't get fired twice?

I am really sorry for the inconvenience this issue causes you and I completely understand that this could bring a negative impact on your work. I converted the internal bug report into a public one- WPF Report Viewer events fires twice and I increased its priority. I also voted for it on your behalf, so when there is an update on the status you will receive a notification.
I also discussed the case with one of our developers, however, I am afraid that currently, we can not provide a workaround for the problem.
Please, let us know if you have any questions.
