TextBlock TextWrapping not wrapping inside StackPanel
===

I have a StackPanel, but the following line :

                    <TextBlock Grid.Row="1" Grid.Column="0" Text="{Binding Notes}" TextWrapping="Wrap"  />

is not Wrapping the Text.

              <StackPanel 
                    Orientation="Vertical">
                <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="auto"/>
                        <ColumnDefinition Width="auto"/>
                        <ColumnDefinition Width="auto"/>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="auto"/>
                        <ColumnDefinition Width="5"/>
                        <ColumnDefinition Width="15"/>
                    </Grid.ColumnDefinitions>
                <Grid.RowDefinitions>
                    <RowDefinition  />
                    <RowDefinition />
                </Grid.RowDefinitions>

                <DockPanel Grid.Row="0" Grid.Column="0" >
                    <TextBlock 
                        Text="{Binding Path=Id, StringFormat='#\{0\}'}" 
                        FontWeight="Bold" 
                        Padding="0,0,5,0"/>
                    <TextBlock
                        Text="{Binding Path=Name}" 
                        FontWeight="Bold" 
                        Padding="0,0,5,0"/>
                </DockPanel>
                    <TextBlock 
                        Grid.Row="0" Grid.Column="4" 
                        Text="{Binding Path=Time, StringFormat={}{0:HH:mm}}" 
                        FontWeight="Bold"/>
                <Image Grid.Row="0" Grid.Column="6" HorizontalAlignment="Center" VerticalAlignment="Center" 
                        Source="{Binding Path=Image, Mode=OneWay, Converter={StaticResource ImageConverter}}"/>

                    <TextBlock Grid.Row="1" Grid.Column="0" Text="{Binding Notes}" TextWrapping="Wrap"  />
            
                    <Image Grid.Row="1" Grid.Column="4" HorizontalAlignment="Center" VerticalAlignment="Top" 
                                Source="{Binding Path=Picture, Mode=OneWay, Converter={StaticResource PictureConverter}}"/>
            </Grid>
        </StackPanel>

The StackPanel Orientation is set to 'Vertical' but the TextBlock is not inheriting it.

Where am I going wrong?

Thanks
