How to set template for listbox in WPF(Windows 10 Weather)

Question

I am trying to create a Windows 10 weather application in WPF using C#. I need to have a Listbox to display recent 10 day weather section. I must set template for Listbox items. I tried this:

<ListBox Grid.Row="1" x:Name="DailyWeatherListBox">
    <ListBox.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel>
                <!--...-->
            </StackPanel>
        </ItemsPanelTemplate>
    </ListBox.ItemsPanel>
</ListBox>

This is the recent 10 day weather section (Windows 10 Weather)

Look the Windows 10 Weather. I put this image for disuse Windows 10. I also don't know how to set Scrollbar in the Listbox corners. I would be very thankful if you could help.

I would start off something like this:

<ListBox ItemsSource="{Binding WeeklyWeather}"
         SelectedItem="{Binding SelectedDailyWeather, Mode=TwoWay}">

    //Use ItemTemplate to set how item looks "inside"
    //I'll leave design details for you
    <ListBox.ItemTemplate>
        <DataTemplate>
            <StackPanel>
                <TextBlock Text="{Binding Day}"/>
                <Image Source={Binding WheatherPicturePath}/>
                <TextBlock Text="{Binding Temperature}"/>
                <TextBlock Text="{Binding Description}"/>
            </StackPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>

    //ItemsPanel defines container for items. It can be StackPanel, Wrapanel, Grid, etc
    <ListBox.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel IsItemsHost="True" Orientation="Horizontal"/>
        </ItemsPanelTemplate>
    </ListBox.ItemsPanel>

    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type ListBoxItem}">
                        //You use this place to design how container normally looks like
                        <Border Background="White">
                            //DataTemplate defined above is placed in ContentPresenter
                            <ContentPresenter />
                        </Border>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
            <Style.Triggers>
                //Here we catch "IsSelected" event and re-design our template to visually reflect "selected"
                <Trigger Property="IsSelected" Value="true">
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate TargetType="{x:Type ListBoxItem}">
                                <Border Background="Gray">
                                    <ContentPresenter />
                                </Border>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Trigger>
            </Style.Triggers>
        </Style>
    </ListBox.ItemContainerStyle>

</ListBox>

Here are couple ideas how for those bindings.

public class WeatherViewModel
{
    public string Day { get; set; }
    public string WheatherPicturePath { get; set; }
    public string Temperature { get; set; }
    public string Description { get; set; }
}

public class BindedDataContext
{
    public ObservableCollection<WeatherViewModel> WeeklyWeather { get; set; }
    public WeatherViewModel SelectedDailyWeather { get; set; }
    //...
}

Your approaches for code-behind may differ, but they need to be in place for you to use those bindings.

For such scrollbar I would look into Change scrollviewer template in listbox
