WPF listbox item not wordwrapping

My ListBox has, amongst other things a description field in it which can be quite long. Instead of having a horizontal scroll bar I want to word wrap it. It works if I set the MaxWidth but since the ListBox changes size I don't want to hard code the value.

What's the best way to do this?

EDIT: The description is in a TextBlock.

Simplified XAML (Removed unnessesary stuff, still shows problem:

         <ListBox BorderThickness="0" Padding="5" Name="lstTasks">
            <ListBox.ItemsSource>
                <Binding Source="{StaticResource dataTasks}"/>
            </ListBox.ItemsSource>

            <ListBox.ItemTemplate>
                <DataTemplate>
                    <Grid>
                        <TextBlock Text="{Binding Path=RequestDescription}" TextTrimming="WordEllipsis" TextWrapping="Wrap" Height="60" />
                    </Grid>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

There isn't meaning of using wrapping and trimming together. You should use one of them texttrimming or textwrapping. It it trims it doesn't wrap.

For textwrapping Matt's answer is correct for trimming you should define width or maxwidth property value.

Its exactly the same for SL developers.

Try forcing the width of your ListBoxItems to be the width of the ListBox:

<ListBox
     Name="lstTasks"
     BorderThickness="0"
     Padding="5"
     HorizontalContentAlignment="Stretch">

Also you might try disabling horizontal scrolling:

<ListBox
     ScrollViewer.HorizontalScrollBarVisibility="Disabled"
     ...>
