Drag and drop of multiple rows between RAD Gridviews

Hi,

first of all, big ups to the Telerik team for the RAD Controls and at the moment especially the RAD Gridview which I'm using in a Project.
Now to my question, I've found some nice and easy ways to do drag'n'drop operations between 1>n RAD Gridviews in my applications, however this is only one row at a time.

Is there some nice way to achieve this with 1-n row(s), like selecting a one or more rows from Gridview A and drag'n'drop them to Another GridView?

I might be blind, but I'm just settling in with the Telerik way of things. :)

How to keep busy indicator spinning during binding?

I fetch my data and populate the underlying ObservableCollection with the fetched data on a background thread using the TPL, during that time the busy indicator is spinning fine. However, once my data is fetched the ICollectionView my RadDataGird is bound to starts refreshing and the busy indicator freezes until the binding is finished which takes longer than fetching the data and makes the UI look unresponsive...

Now, it makes sense because both the data binding and the busy indicator are running on the UI thread but if that is the case what is the solution to keep the busy indicator spinning during the data binding?

Is there any way to have the busy indicator run on a separate thread?
