Add Handler For Child Control Event

[Kevin Marois]

This is a bit long, but it should be easy to understand... I created a simple navigation CustomControl, with Today, Previous, and Next buttons. It has a routed event called NavigationSelectedEvent. The event is called from the three button's comands: Style

    <Setter Property="Template">

        <Setter.Value>

            <ControlTemplate TargetType="{x:Type views:NavigationView}">

                <Border x:Name="border"
                        Background="{StaticResource brushActiveBack}" 
                        BorderBrush="{StaticResource brushPeriodBorder}"
                        BorderThickness="1,1,0,0"
                        Margin="{Binding Margin, RelativeSource={RelativeSource TemplatedParent}}"
                        Padding="{Binding Padding, RelativeSource={RelativeSource TemplatedParent}}">

                    <Grid>

                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="Auto"/>
                            <ColumnDefinition Width="Auto"/>
                            <ColumnDefinition Width="Auto"/>
                        </Grid.ColumnDefinitions>

                        <Button Grid.Column="0"
                                Content="Today"
                                Height="28"
                                Width="85"
                                Margin="2,2,2,2"
                                Command="{Binding NavigateTodayCommand, RelativeSource={RelativeSource TemplatedParent}}"/>

                        <Button Grid.Column="1"
                                Content="&lt;"
                                Height="28"
                                Width="85"
                                Margin="0,2,2,2"
                                Command="{Binding NavigatePreviousCommand, RelativeSource={RelativeSource TemplatedParent}}"/>

                        <Button Grid.Column="2"
                                Content="&gt;"
                                Height="28"
                                Width="85"
                                Margin="0,2,2,2"
                                Command="{Binding NavigateNextCommand, RelativeSource={RelativeSource TemplatedParent}}"/>

                    </Grid>

                </Border>

            </ControlTemplat</x-turndown>
