long list selector jump list scren windows phone

Question

I'm using a grouped long list selector in a windows phone application. It has the normal behaviour, whenever I tap on one header, the jump list screen is open. However, I want to trigger this when I'm navigating on the page without any interaction from the user. Is there a possibility to display the jump list when navigating to a page without any user interaction? Thank you

<phone:LongListSelector
                Height="570"
                Margin="0,-10,0,0"
                VerticalAlignment="Top"
                LayoutMode="List"
                x:Name="SizeLLs"
                SelectionChanged="LongListSelector_SelectionChanged_1"
                ItemsSource="{Binding Path=CurrentProduct.product_variations, Source={StaticResource LocalVariablesResources}}">
    <phone:LongListSelector.ItemTemplate>
        <DataTemplate>
            <Grid Margin="12,10">

            </Grid>
        </DataTemplate>
    </phone:LongListSelector.ItemTemplate>

No, unfortunately for you, LongListselector doesn't have this functionality publically exposed.

You could take the WP7 source code of the control , and add the functionality you need (ie make OpenPopup method public).
