Hi Stef:
Thank you for the help on the binding redirects, I think it is working now, I was not adding the correct dependencies in the project.
Now that I'm finally working with the report viewer inside our master project the need to get data bound from the gridview is very much a priority for me. I'm still new to WPF but I want to make sure I understand your reply,
* My ViewModel will have a MydataSource property
* I have one reportviewer that needs the reflect the data from two gridviews and a radchart control. For now I want to be comfortable getting data from just one of the gridviews so I should new a MydataSource on the event of the gridview changing? I will do this in code in the ViewModel?
Mike
