Hi there - I'm Aly,
I've seen your post and I'm interested. Honestly, I don't have much experience with Telerik or DevExpress; however, I've had much experience in WPF and multi-threaded programming, thus, I understand how threading works and when/how to run the operation on UI thread and how/when to run the operation on a parallel thread. I'd like to have a look over the project and I'd like to listen to any further brief you might like to share. Feel free to contact me so we can talk further.
Sincerely,
Aly El-Haddad
