Answer 1

Bind a property to CanUserDeleteRows.

XAML:

CanUserDeleteRows="{Binding UserCanDelete}"

ViewModel:

    public bool UserCanDelete
    {
        get
        {
            // return a value based on the currently selected item and business rules
        }
    }

Make sure you're raising a PropertyChanged event for this property somewhere, where you do that would depend on the other data changes that affect your return value.
