Hub Control Universal Windows Apps

I'm building an universal application for windows (windows 8.1 and windows phone 8.1). I want to use a hub control with only 2 tabs, but for some reason the background won't continue or it won't show the background on the second tab. When I only have one tab it will show a black line on the right. Is there a way to fix those things?

Regards,

Tom

By request i pasted my code. The hubsection can be placed several times. When there is only one or two it won't work. When you add the third it will

I'm not sure if this still holds true but according to the linked article the Hub control does not scroll infinitely when it has only one section...

Try this 

<Hub Header="The Header" Margin="0,27,0,0">

        <Hub.HeaderTemplate>
            <DataTemplate>
                <TextBlock Text="The Text" FontSize="66"></TextBlock>
            </DataTemplate>
        </Hub.HeaderTemplate>

        <Hub.Background>
            <ImageBrush ImageSource="Assets/TheBackground.jpg" Stretch="UniformToFill"/>
        </Hub.Background>
</Hub>

I think the problem does not come from the HUB, or the number of HubSections you use. I've used the following code:

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <Grid x:Name="LayoutRoot">
        <Hub x:Name="Hub" x:Uid="Hub" Header="ducommerce" Background="{StaticResource background}">
            <HubSection x:Uid="HubSection1" Header="{Binding SpecialDishes.Name}" >
                <DataTemplate>
                    <ListView
                ItemsSource="{Binding Items}"
                IsItemClickEnabled="True">
                        <ListView.ItemTemplate>
                            <DataTemplate>
                                <Button Content="testbtn"></Button>
                            </DataTemplate>
                        </ListView.ItemTemplate>
                        <ListView.ItemContainerStyle>
                            <Style TargetType="ListViewItem">
                                <Setter Property="Padding" Value="0"/>
                                <Setter Property="Margin" Value="0,0,0,12"/>
                            </Style>
                        </ListView.ItemContainerStyle>
                    </ListView>
                </DataTemplate>
            </HubSection>
            <HubSection x:Uid="HubSection1" Header="{Binding SpecialDishes.Name}" >
                <DataTemplate>
                    <ListView
                ItemsSource="{Binding Items}"
                IsItemClickEnabled="True">
                        <ListView.ItemTemplate>
                            <DataTemplate>
                                <Button Content="testbtn"></Button>
                            </DataTemplate>
                        </ListView.ItemTemplate>
                        <ListView.ItemContainerStyle>
                            <Style TargetType="ListViewItem">
                                <Setter Property="Padding" Value="0"/>
                                <Setter Property="Margin" Value="0,0,0,12"/>
                            </Style>
                        </ListView.ItemContainerStyle>
                    </ListView>
                </DataTemplate>
            </HubSection>

            <!--<HubSection x:Uid="HubSection1" Header="{Binding SpecialDishes.Name}" >
                <DataTemplate>
                    <ListView
                ItemsSource="{Binding Items}"
                IsItemClickEnabled="True">
                        <ListView.ItemTemplate>
                            <DataTemplate>
                                <Button Content="testbtn"></Button>
                            </DataTemplate>
                        </ListView.ItemTemplate>
                        <ListView.ItemContainerStyle>
                            <Style TargetType="ListViewItem">
                                <Setter Property="Padding" Value="0"/>
                                <Setter Property="Margin" Value="0,0,0,12"/>
                            </Style>
                        </ListView.ItemContainerStyle>
                    </ListView>
                </DataTemplate>
            </HubSection>-->
        </Hub>
    </Grid>
</Grid>

And the background is displayed on every HubSection, whether there are 1, 2 or 3. Try your code with another brush than your "HubBackgroundImageBrush", like a color brush, and see if it is shown.

You probably see this by now. But...

  1. Your Hub only has a single HubSection, you think it has two.
  2. Your Hub.Background is being set, not your HubSection.Background

Best of luck!
