Use different template for last item in a WPF itemscontrol

Question

I'm using a custom template in my itemscontrol to display the following result:

item 1, item 2, item3,

I want to change the template of the last item so the result becomes:

item 1, item2, item3

The ItemsControl:

<ItemsControl ItemsSource="{Binding Path=MyCollection}">

    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Horizontal" IsItemsHost="True"/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>

    <ItemsControl.ItemTemplate>
        <DataTemplate>

            <StackPanel Orientation="Horizontal">
                <TextBlock Text="{Binding Path=Name}"/>
                <TextBlock Text=", "/>
            </StackPanel>

        </DataTemplate>
    </ItemsControl.ItemTemplate>

</ItemsControl>

Is there anyone who can give a solution for my problem? Thank you!

I've found the solution for my problem using only XAML. If there is anybody who needs to do the same, use this:

<ItemsControl ItemsSource="{Binding Path=MyCollection}">

    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Horizontal" IsItemsHost="True"/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>

    <ItemsControl.ItemTemplate>
        <DataTemplate>

            <StackPanel Orientation="Horizontal">
                <TextBlock x:Name="comma" Text=", "/>
                <TextBlock Text="{Binding}"/>
            </StackPanel>

            <DataTemplate.Triggers>
                <DataTrigger Binding="{Binding RelativeSource={RelativeSource PreviousData}}" Value="{x:Null}">
                    <Setter TargetName="comma" Property="Visibility" Value="Collapsed"/>
                </DataTrigger>
            </DataTemplate.Triggers>

        </DataTemplate>
    </ItemsControl.ItemTemplate>

</ItemsControl>
