ItemsCollection and alternate row coloring

I've got an itemscollection and I want to have alternate row colouring, I've looked about how to do this but can't find anything, I think this should be simple but maybe I'm missing something.

It's WPF btw.

<Grid>
        <ItemsControl Name="itemsControl">
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="*"/>
                            <ColumnDefinition Width="*"/>
                            <ColumnDefinition Width="80"/>
                        </Grid.ColumnDefinitions>
                        <TextBlock Grid.Column="0" Text="{Binding Path=name}" VerticalAlignment="Center"/>
                        <TextBlock Grid.Column="1" Text="{Binding Path=something}" VerticalAlignment="Center"/>
                        <Button Grid.Column="2" Content="Launch" Tag="{Binding}" Height="25" VerticalAlignment="Center" Click="Button_Click"/>
                    </Grid>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
            <ItemsControl.ItemContainerStyle>
                <Style>
                    <Setter Property="Control.Margin" Value="5"/>
                </Style>
            </ItemsControl.ItemContainerStyle>
        </ItemsControl>
        <Button Height="23" HorizontalAlignment="Right" Margin="0,0,12,12" Name="button1" VerticalAlignment="Bottom" Width="75" Click="button1_Click">Button</Button>
    </Grid>
Solution

  • Add AlternationCount="2" to your ItemsControl.

    Then add this to your ItemContainerStyle to get alternating red/blue items:

    <Style.Triggers>
  <Trigger Property="ItemsControl.AlternationIndex" Value="0">
    <Setter Property="Control.Background" Value="Red"></Setter>
  </Trigger>
  <Trigger Property="ItemsControl.AlternationIndex" Value="1">
    <Setter Property="Control.Background" Value="Blue"></Setter>
  </Trigger>
</Style.Triggers>

    Edit: you need to have the .NET 3.0/3.5 SP1.
