ListBox template, hiding elements - xaml

Question

I have a listbox template showing an image and three textboxes. You will see how are they distributed in the code below. My problem is that some items won't have an image and I want the text to fill the whole row in that case.
I've tried not to use a grid, to use a canvas, but I don't know why, when using a canvas inside a listbox, nothing is shown. I don't know if this is easy to accomplish. Here's the code:
<ListBox Grid.Column="0" Grid.Row="1" Background="White" HorizontalAlignment="Stretch" Name="itemList" VerticalContentAlignment="Stretch" SelectionChanged="listBoxSetmana_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" MinWidth="480">
<Grid.RowDefinitions>
<RowDefinition Height="28" />
<RowDefinition Height="17" />
<RowDefinition Height="50" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="60" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Border HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Grid.RowSpan="3" Grid.Column="0" Grid.Row="0" BorderThickness="1" BorderBrush="#FFFF003F" Padding="1">
<Image HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Name="listImage" Width="36" Height="36" Source="{Binding thumbnail}" />
</Border>
<TextBlock Padding="0 0 25 0" Grid.Column="1" Grid.Row="0" Name="title" Foreground="Black" Text="{Binding title}" FontWeight="Bold" FontSize="20" />
<TextBlock Padding="0 0 25 0" Grid.Column="1" Grid.Row="1" Name="published" Foreground="Black" Text="{Binding published}" FontSize="13" />
<TextBlock Padding="0 0 25 0" Grid.Column="1" Grid.Row="2" Name="subtitle" Foreground="Black" Text="{Binding subtitle}" FontSize="16" TextWrapping="Wrap" />
<TextBlock Visibility="Collapsed" Text="{Binding id}" />
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Thank you!

There are several ways to bind this together.
One way is:
add some Padding to the Border
bind the Visibility of the Border to the thumbnail Property using an appropriate ValueConverter
change the width of Column 0 from "60" to "Auto" - then it will disappear when the image is Collapsed.
