SelectedColor of Graphics Layer

EdwardSon

This is what I have so far:

<esri:Map x:Name="Map" HorizontalAlignment="Stretch" IsLogoVisible="False"  VerticalAlignment="Stretch"
                      Grid.ColumnSpan="2" Grid.RowSpan="2" WrapAround="True"
                d:DataContext="{Binding Converter={StaticResource SampleGraphicsLayerConverter}, RelativeSource={RelativeSource Self}}">
                <esri:Map.Resources>
                    <esri:FillSymbol x:Key="SelectFillSymbol">
                        <esri:FillSymbol.ControlTemplate>
                            <ControlTemplate>
                                <Path x:Name="Element"
       Stroke="Black"
       StrokeStartLineCap="Round"
       StrokeThickness="2"
       StrokeLineJoin="Round"
       StrokeEndLineCap="Round"
       Fill="Blue">
                                    <VisualStateManager.VisualStateGroups>
                                        <VisualStateGroup x:Name="SelectionStates">
                                            <VisualState x:Name="Unselected" >
                                                <Storyboard>
                                                    <ColorAnimation Storyboard.TargetName="Element"
           Storyboard.TargetProperty="(Path.Fill).(SolidColorBrush.Color)"
           To="Blue"  Duration="00:00:00.25"/>
                                                </Storyboard>
                                            </VisualState>
                                            <VisualState x:Name="Selected">
                                                <Storyboard>
                                                    <ColorAnimation Storyboard.TargetName="Element"
           Storyboard.TargetProperty="(Path.Fill).(SolidColorBrush.Color)"
           To="Yellow" Duration="00:00:00.25"/>
                                                    <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Element" Storyboard.TargetProperty="StrokeDashArray">
                                                        <DiscreteObjectKeyFrame KeyTime="0:0:0">
                                                            <DiscreteObjectKeyFrame.Value>
                                                                <DoubleCollection>2,1</DoubleCollection>
                                                            </DiscreteObjectKeyFrame.Value>
                                                        </DiscreteObjectKeyFrame>
                                                    </ObjectAnimationUsingKeyFrames>
                                                </Storyboard>
                                            </VisualState>
                                        </VisualStateGroup>
                                    </VisualStateManager.VisualStateGroups>
                                </Path>
                            </ControlTemplate>
                        </esri:FillSymbol.ControlTemplate>
                    </esri:FillSymbol>
                </esri:Map.Resources>
            </esri:Map>

and

foreach (Graphic graphic in featureSet.Features)
            {
                graphic.Symbol = MapApplication.Current.Map.Resources["SelectFillSymbol"] as Symbol;
                graphicsLayer.Graphics.Add(graphic);
            }

where featureSet is the result of a query.

Everything goes fine and when I run the application I can see that the graphic flashes Blue initially, indicating it takes the applied style for the symbol.
But then it resets itself to what it was before the templated custom symbol is applied.

Why does it reset?

But then it resets itself to what it was before the templated custom symbol is applied.

What do you mean by 'then'? Is it due to a user action or to the execution of another code?

I don't understand either what you mean by 'what it was before the templated custom symbol is applied' ? Your graphics seem directly created with your custom symbol.
