To use date ranges with that info strips sample, you need to set UseDates = true on the strips.

Hope this helps!

Hi Graham,

It is working fine now.

Thanks

By the way, this DataTemplate may work better for when you have thin strips such as that, to avoid label clipping.

<DataTemplate x:Key="VerticalInfoStripTemplate">
            <Grid Margin="0" Width="{Binding Width}" Height="{Binding Height}">
                <Rectangle Fill="{Binding Fill}" Opacity="1" />
                <Canvas HorizontalAlignment="Right" VerticalAlignment="Top">
                    <Grid Margin="0" Width="{Binding Height}" Height="{Binding Width}">
                        <Grid.RenderTransform>
                            <RotateTransform Angle="90" />
                        </Grid.RenderTransform>
                        <TextBlock 
                            VerticalAlignment="Center" 
                            HorizontalAlignment="Center" 
                            Foreground="DimGray" FontSize="30" 
                            FontWeight="Bold" Text="{Binding Label}" >
                    <ToolTipService.ToolTip>
                        <Grid>
                            <Grid.RowDefinitions>
                                <RowDefinition Height="25" />
                                <RowDefinition Height="25" />
                                <RowDefinition Height="25" />
                                <RowDefinition Height="25" />
                            </Grid.RowDefinitions>
                            <Grid.ColumnDefinitions>

                                <ColumnDefinition Width="200" />
                            </Grid.ColumnDefinitions>
                            <TextBlock Text="Test0" Grid.Column="0" Grid.Row="0" />
                            <TextBlock Text="Tes0" Grid.Column="1" Grid.Row="0" />
                            
                            <TextBlock Text="Test1" Grid.Column="0" Grid.Row="1" />
                            <TextBlock Text="Test1" Grid.Column="1" Grid.Row="1" />
                            
                            <TextBlock Text="Test2" Grid.Column="0" Grid.Row="2" />
                            <TextBlock Text="Test2" Grid.Column="1" Grid.Row="2" />
                            
                            <TextBlock Text="Test3" Grid.Column="0" Grid.Row="3" />
                            <TextBlock Text="Test3" Grid.Column="1" Grid.Row="3" />
                        </Grid>
                    </ToolTipService.ToolTip>
                </TextBlock>
                    </Grid>
                </Canvas>
            </Grid>
        </DataTemplate>

Alternatively you could use the LayoutTransformer in the Silverlight Toolkit to apply layout transforms to the labels rather than render transfroms.
