I am using XamDataGrid Validation Feature.In the XamDataGrid i am validating the XamCheckEditor

Value whether the user selects the XamCheckEditor. I am able to set the Tooltip but i unable to set the

BorderBrush to Red. The following code doesn't have any effect.

 <Style.Triggers>  

                        <Trigger Property="IsValueValid" Value="false">  

                            <Trigger.Setters>  

                                <Setter Property="BorderBrush" Value="Red" />  

                            </Trigger.Setters>  

                        </Trigger>  

                    </Style.Triggers>
