                                <VisualState x:Name="MouseOver">

                                    <Storyboard>

                                        <ObjectAnimationUsingKeyFrames Duration="0" Storyboard.TargetName="ButtonContentGrid"  Storyboard.TargetProperty="(Grid.Background).(ImageBrush.ImageSource)">                                                                 

                                            <DiscreteObjectKeyFrame KeyTime="0">

                                                <DiscreteObjectKeyFrame.Value>

                                                    <Image Source="Temp/test_mouseover.PNG"/>

                                                </DiscreteObjectKeyFrame.Value>

                                            </DiscreteObjectKeyFrame>                                            

                                        </ObjectAnimationUsingKeyFrames>                                       

                                    </Storyboard>

                                </VisualState>       </Storyboard>

                                </VisualState>
