Drag control problem

[HenJigg]

Do controls of two different data types allow dragging? Or during the drag process, change the data type to be consistent with the drag target type. Is this allowed?

example:

<ListBox ItemsSource="{Binding List}" />
<ListBox ItemsSource="{Binding ListTwo}" />

public ObservableCollection List;
public ObservableCollection ListTwo;

ClassA:{
...
}

ClassB:{
...
}
