<DataTemplate> <StackPanel x:Name="stackPanel" Height="{Binding Length}" Background="{Binding Brush}" HorizontalAlignment="Stretch"> <TextBlock FontSize="50" Text="{Binding Num}" HorizontalAlignment="Center" VerticalAlignment="Center"/> <RichTextBlock HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Paragraph> bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10bug10 </Paragraph> </RichTextBlock> </StackPanel> </DataTemplate>
