hi i'm new to wpf..i'm using a listbox inside inside another.. the items inside the two listbox should appear one below the other with alternate colors.. i could successfully set alternate row colors for items of individual listboxes.. but how do i do it when i'm using the listboxes one inside another? i'm using datatemplates.

because i'm using one listbox another the colors of the items look somewhat like this:

gray ->listbox 1
yellow ->listbox 1
gray -> listbox 1
gray ->listbox 2 (this color should be ideally yellow)
yellow ->listbox 2 (this color should be gray)

Set the AlternationCount property of the ListView and use a trigger or bind to ItemsControl.AlternationIndex in order to set the background color.

Edit sorry miss read, I've changed the xaml below so the first item in the inner ListView is yellow.

XML

<UserControl x:Key="test">
    <UserControl.Resources>
        <Style x:Key="itemStyle" TargetType="{x:Type ListViewItem}">
            <Style.Triggers>
                <Trigger Property="ItemsControl.AlternationIndex" Value="0">
                    <Setter Property="Background" Value="Grey" />
                </Trigger>
                <Trigger Property="ItemsControl.AlternationIndex" Value="1">
                    <Setter Property="Background" Value="Yellow" />
                </Trigger>
            </Style.Triggers>
        </Style>
        <Style x:Key="itemStyle2" TargetType="{x:Type ListViewItem}">
            <Style.Triggers>
                <Trigger Property="ItemsControl.AlternationIndex" Value="0">
                    <Setter Property="Background" Value="Yellow" />
                </Trigger>
                <Trigger Property="ItemsControl.AlternationIndex" Value="1">
                    <Setter Property="Background" Value="Grey" />
                </Trigger>
            </Style.Triggers>
        </Style>
    </UserControl.Resources>

    <ListView AlternationCount="2" ItemContainerStyle="{StaticResource itemStyle}">
        <ListView.ItemTemplate>
            <DataTemplate>
                <ListView AlternationCount="2" ItemContainerStyle="{StaticResource itemStyle2}" />
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>
</UserControl>
