Hi Dean,
The loading time you are experiencing is definitely not normal. However, from the provided code I am not able to confirm what the exact cause for it might be. I set up a demo application demonstrating the normal loading behavior of RadGridView. Since you confirmed that the items are loaded in the collection you are using as an ItemsSource of the control, would it be possible for you to modify the sample project so that such performance degradation can be reproduced and send it as an attachment in a new support ticket?
