how to dynamically change listview items styles during runtime?

I am using VS2010 - wpf - C#

I have a listview that shows securities prices and I want to style the listview rows in three different ways : green - red - and orange

I don't know how to write a C# code that would affect the styles of these listview items during runtime under some conditions that I have ???

I don't know if my question needs some more explanation but if it does please let me know

Best Regards to everyone

Why do you want to do it at runtime instead of in the XAML?

I am assuming the red/green/orange has some kind of meaning. Setup a DataTrigger on the Listbox's ItemContainerStyle which modifies the color based on a value.

Here's an example using a property named Priority on the ListView items

<ListView>
    <ListView.ItemContainerStyle>
        <Style TargetType="{x:Type ListBoxItem}">
            <Setter Property="Foreground" Value="Green" />
            <Style.Triggers>
                <DataTrigger Binding="{Binding Priority}" Value="2">
                    <Setter Property="Foreground" Value="Orange" />
                </DataTrigger>
                <DataTrigger Binding="{Binding Priority}" Value="3">
                    <Setter Property="Foreground" Value="Red" />
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </ListView.ItemContainerStyle>
</ListView>
