Use same VisualStateGroup in all different ListViewItem style

Question

Hello everyone.

I'd like to make my VisualStateGroup unique for all ListViewItem, so that any ListViewItem style, even different, can use the same VisualStateGroup, without repeating in the ListViewItem style.

Declare the VisualStateGroup once and all different item styles can use it.

Something like:

Externalized VisualStateGroup:

                                <VisualStateGroup x:Name="CommonStates">
                                    <VisualState x:Name="Normal" />
                                    <VisualState x:Name="PointerOver">
                                        <Storyboard>
                                            <DoubleAnimation Storyboard.TargetName="MyGrid"
                                                             Storyboard.TargetProperty="Opacity"
                                                             To="1"
                                                             Duration="0" />
                                            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="MyGrid" Storyboard.TargetProperty="BorderBrush">
                                                <DiscreteObjectKeyFrame KeyTime="0" Value="yellow" />
                                            </ObjectAnimationUsingKeyFrames>
                                            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="MyGrid" Storyboard.TargetProperty="Background">
                                                <DiscreteObjectKeyFrame KeyTime="0" Value="yellow" />
                                            </ObjectAnimationUsingKeyFrames>
                                        </Storyboard>
                                    </VisualState>
                                    <VisualState x:Name="Pressed">
                                        <Storyboard>
                                            <DoubleAnimation Storyboard.TargetName="MyGrid"

                                                             Duration="0" />
                                            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="MyGrid" Storyboard.TargetProperty="Background">
                                                <DiscreteObjectKeyFrame KeyTime="0" Value="red" />
                                            </ObjectAnimationUsingKeyFrames>

                                                             To="1"
                                                             Duration="0" />

                                    </VisualState>
                                </VisualStateGroup>

ListViewItemStyle1:

	<Style x:Key="ListViewItemStyle1" TargetType="ListViewItem">
            <Setter Property="CornerRadius" Value="0" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ListViewItem">

                            <ContentPresenter x:Name="ContentPresenter" />
                            <VisualStateManager.VisualStateGroups>

                                //External VisualStateGroup

                            </VisualStateManager.VisualStateGroups>
                        </Grid>

                </Setter.Value>
            </Setter>
        </Style>

ListViewItemStyle2:

	<Style x:Key="ListViewItemStyle2" TargetType="ListViewItem">
            <Setter Property="CornerRadius" Value="0" />
            <Setter Property="Template">
                <Setter.Value>

                        <Grid x:Name="MyGrid"
                              Height="90" Width="700">
                            <ContentPresenter x:Name="ContentPresenter" />
                            <VisualStateManager.VisualStateGroups>

                                //External VisualStateGroup

                            </VisualStateManager.VisualStateGroups>
                        </Grid>

                </Setter.Value>
            </Setter>
        </Style>

Note that "MyGrid" exists in all ListViewItem styles.

Thank you all.
