Question

I have created Panorama control and binded PanoramaItem from ItemSource. Now when i am changing the selected Panoramaitem by swiping over them the Selected index is always set to -1. I dont know what wrong i am doing while implementation. neither selectionchange event is getting fired. Code:

<phone:Panorama Grid.Row="1"  Visibility="Visible"
       x:Name="PnrVwMainNews"
       ItemsSource="{Binding ParnormaItemsData}"
       ItemContainerStyle="{StaticResource PanoramaContainerItemStyle}">
    <phone:Panorama.ItemTemplate>
        <DataTemplate>
            <!-- Panorma Items Template -->
            <Controls:DynamicContentControl Content="{Binding UsrCntrlDynamic}" />
        </DataTemplate>
    </phone:Panorama.ItemTemplate>
</phone:Panorama>

PanoramaContainerItemStyle

<Style x:Key="PanoramaContainerItemStyle" TargetType="phone:PanoramaItem">
        <Setter Property="HorizontalContentAlignment" Value="Stretch" />
        <Setter Property="VerticalContentAlignment" Value="Stretch" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="phone:PanoramaItem">
                    <Grid Background="{TemplateBinding Background}" Margin="12,0,0,0">
                        <Grid.RowDefinitions>
                            <RowDefinition Height="auto" />
                            <RowDefinition Height="*" />
                        </Grid.RowDefinitions>

                        <ContentPresenter Content="{TemplateBinding Content}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" Grid.Row="1" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

I can't see any Selection_Changed event implemented/hooked here.

SelectionChanged="Panorama_SelectionChanged"

You should at first define this event on Panorama level. (Not inside the PanoramaContainerItemStyle)

assign null to SelectedItem at last in SelectionChanged event handler, so that new item will get selected every time.
