I cannot determine how to scroll horizontally using the mouse wheel. Vertical scrolling works well automatically, but I need to scroll my content horizontally. My code looks like this:

<ListBox x:Name="receiptList"
         Margin="5,0"
         Grid.Row="1"
         ItemTemplate="{StaticResource receiptListItemDataTemplate}"
         ItemsSource="{Binding OpenReceipts}"
         ScrollViewer.VerticalScrollBarVisibility="Disabled">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Horizontal"
                        ScrollViewer.HorizontalScrollBarVisibility="Visible"/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
</ListBox>

My item template looks like this:

<DataTemplate x:Key="receiptListItemDataTemplate">
    <RadioButton GroupName="Numbers"
                 Command="{Binding Path=DataContext.SelectReceiptCommand,RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type POS:PointOfSaleControl}}}"
                 CommandParameter="{Binding }"
                 Margin="2,0"
                 IsChecked="{Binding IsSelected}">
        <RadioButton.Template>
            <ControlTemplate TargetType="{x:Type RadioButton}" >
                <Grid x:Name="receiptGrid" >
                    <Grid>
                        <Border BorderThickness="2" 
                                BorderBrush="Green" 
                                Height="20" 
                                Width="20">
                            <Grid x:Name="radioButtonGrid" 
                                  Background="DarkOrange">
                                <TextBlock x:Name="receiptLabel"
                                           HorizontalAlignment="Center"
                                           VerticalAlignment="Center"
                                           Text="{Binding Path=NumberInQueue, Mode=OneWay}"
                                           FontWeight="Bold"
                                           FontSize="12"
                                           Foreground="White">
                                </TextBlock>
                            </Grid>
                        </Border>
                    </Grid>
                </Grid>

                <ControlTemplate.Triggers>
                    <Trigger Property="IsChecked" Value="True">
                        <Setter Property="Margin" 
                                TargetName="receiptGrid" 
                                Value="2,2,-1,-1"/>
                        <Setter Property="Background"
                                TargetName="radioButtonGrid" 
                                Value="Maroon"/>
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </RadioButton.Template>
    </RadioButton>          
</DataTemplate>

Is there another method or control that I need to add to get that functionality?

I was kinda looking for the most simple way to make any ScrollViewer scroll left-right instead of up-down. So here is the simplest combination of the other answers. 

<ScrollViewer HorizontalScrollBarVisibility="Visible"
              PreviewMouseWheel="ScrollViewer_PreviewMouseWheel">

and: 

private void ScrollViewer_PreviewMouseWheel(object sender, MouseWheelEventArgs e)
{
    ScrollViewer scrollViewer = (ScrollViewer)sender;
    if (e.Delta < 0)
    {
        scrollViewer.LineRight();
    }
    else
    {
        scrollViewer.LineLeft();
    }
    e.Handled = true;
}

This is basically what John Gardner suggested just with the actual code. I'm also quoting my answer from similar question here.
