Hi. I'm using a ControlTemplate to style map objects:

    <ControlTemplate x:Key="EndPointStyle">
        <Grid>
            <VisualStateManager.VisualStateGroups>
                <VisualStateGroup x:Name="CommonStates">
                    <VisualState x:Name="Normal">
                        <Storyboard>
                            <DoubleAnimation BeginTime="00:00:00" Storyboard.TargetName="StateEllipse" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleY)" To="1" Duration="0:0:0.1" />
                        </Storyboard>
                    </VisualState>
                    <VisualState x:Name="MouseOver">
                        <Storyboard>
                            <DoubleAnimation BeginTime="00:00:00" Storyboard.TargetName="StateEllipse" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleY)" To="1.1" Duration="0:0:0.1" />
                        </Storyboard>
                    </VisualState>
                    <VisualState x:Name="Working">
                        <Storyboard RepeatBehavior="Forever">
                            <DoubleAnimation BeginTime="0" Storyboard.TargetName="StateEllipse" Storyboard.TargetProperty="RenderTransform.(ScaleTransform.ScaleX)" From="1" To="3" Duration="00:00:01" />
                            <DoubleAnimation BeginTime="0" Storyboard.TargetName="StateEllipse" Storyboard.TargetProperty="RenderTransform.(ScaleTransform.ScaleY)" From="1" To="3" Duration="00:00:01" />
                            <DoubleAnimation BeginTime="0" Storyboard.TargetName="StateEllipse" Storyboard.TargetProperty="(UIElement.Opacity)" From="1" To="10" Duration="00:00:01" />
                        </Storyboard>
                    </VisualState>
                </VisualStateGroup>
            </VisualStateManager.VisualStateGroups>


            <Ellipse RenderTransformOrigin="0.5,0.5"  x:Name="StateEllipse" Fill="{Binding Symbol.Color}"
                     Width="{Binding Symbol.Size}" Height="{Binding Symbol.Size}">
                <Ellipse.RenderTransform><ScaleTransform /></Ellipse.RenderTransform>
            </Ellipse>


            <Rectangle RenderTransformOrigin="0.5,0.5" Width="{Binding Symbol.Size}" Height="{Binding Symbol.Size}">
                <Rectangle.Fill><ImageBrush ImageSource="{Binding Symbol.Image}"></ImageBrush></Rectangle.Fill>
            </Rectangle>


            <Grid Margin="-200,-16,-200,0" MaxWidth="400" x:Name="SymbolText" HorizontalAlignment="Center>
                <TextBlock Foreground="Black" FontWeight="Bold" Text="{Binding Symbol.Text}" />
            </Grid>
        </Grid>
    </ControlTemplate>

Map object is created like this:

            var ct = _styles[TemplateName] as ControlTemplate;
            if (ct != null)
            {
                ct.LoadContent();
                var icon = IconManager.GetImageByName(ImageName, false);
                Symbol = new StateMarkerSymbol(this)
                {
                    Size = icon.PixelHeight,
                    Image = icon,
                    ControlTemplate = ct,
                };
            }

Is there any way to change object visual state to "Working" from c# code ?

There is no easy way to change the symbol visualstates from code.

The problem being that the underlying UI element under a graphic is hidden.
