Hi,
Is it possible to process this method in background using BackgroundWorker or some other method using code-behind? My UI seems to freeze when I perform this as I have this hooked up to Diagram_MouseLeave event. It takes time as I have image as item in the background that gets written to a property in Viewmodel.

Hello Deepak Shakya,
The RadDiagram and it's children(shapes, connections, etc.) are UI elements and they are used by the UI thread. These elements and their properties can only be accessed and modified using the UI thread. Due to this reason the method ExportToImage cannot be processed in another thread as it needs access to properties of the visual elements.
However, if you need to access the UI thread from another thread you can do this using a Dispatcher. Please note that this will make all calculations in the UI thread.

Thanks for the answer Ivan. I don't this will work in my situation as it will have to access the UI thread and perform calculation there. I might have to assign this to button_click event.
