Question

I’m doing this Windows Phone application sample and after creating a listbox inside a stackpanel everything was ok. But after sometime I get this error :

Below is the code for listbox I created in stackpanel :

<ListBox Margin="0,0,-12,0"
         Name="listBox1">
  <StackPanel Orientation="Horizontal"
              Margin="0,0,17,0">
    <Image Source="icons/star.png"
           Height="100"
           Width="100"
           Margin="12,0,9,0">
    </Image>
    <StackPanel Width="311">
      <TextBlock Text="Folders"
                 TextWrapping="Wrap"
                 Style="{StaticResource PhoneTextExtraLargeStyle}" />
      <TextBlock Text="my personal images"
                 TextWrapping="Wrap"
                 Margin="12,-6,12,0,"
                 Style="{StaticResource PhoneTextSubtleStyle}" />
    </StackPanel>
</ListBox>

Why do I get this error?

According to the error message, you’re trying to set 12,-6,12,0, as a thickness (probably a margin or a padding). Remove the trailing comma and it should work: 12,-6,12,0
