WindowsFormsEditorServiceContainer esc = new WindowsFormsEditorServiceContainer(null);
    PropertyDescriptor pd = TypeDescriptor.GetProperties(instance)[propertyName];
    TypeDescriptorContext tdc = new TypeDescriptorContext(instance, pd);
    tdc.ServiceProvider = esc;
    object v = ce.EditValue(tdc, esc, ((ICloneable) pd.GetValue(instance)).Clone());
