See anything wrong with the following XAML:

<ItemsControl ItemsSource="{Binding GridColumns}" Grid.Row="1" Grid.Column="0">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Margin="0,14" Height="22" >
<TextBlock TextAlignment="Center" Text="{Binding Name}"></TextBlock>
<i:Interaction.Triggers>
<i:EventTrigger EventName="Clicked">
<n:ExecuteCommandAction Command="{Binding HighlightColumn}" Parameter="{Binding Index}" />
</i:EventTrigger>
</i:Interaction.Triggers>
</Button>
</DataTemplate>
</ItemsControl.ItemTemplate>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" >
</StackPanel>
</ItemsPanelTemplate>
</ItemsControl>
