Question

How is it possible to highlight the selected item in the new LongListSelector on Windows Phone 8? Actually nothing happend if I tapped one entry of the list. My list only contains a simple string which will be displayed through a TextBlock. But I want to highlight the selection of the user.

Thanks.

In my case I used a RadioButtonControl in the DataTemplate of the LongListSelectorItem to achieve this. You will have a checked oder unchecked sign at the left border.

In any case it is important, that you set the same group for all Radiobuttons, so the selection only represents one entry.

Inside the Contentor your RadioButton you can put the TextBlock bound to the String.

Im currently not at home, but if this wont solve your problem, I’ll provide you some code when I’m at home 😉

Here you go:

<LongListSelector.ItemTemplate>
    <DataTemplate>
        <ContentControl HorizontalAlignment="Stretch" HorizontalContentAlignment="Left">
            <RadioButton HorizontalAlignment="Stretch" Margin="0,0,0,0" GroupName="A" Background="Black" >
                <StackPanel toolkit:TiltEffect.IsTiltEnabled="True">
                    <TextBlock Text="{Binding Path=XXX}" 
                               TextWrapping="Wrap"
                               Foreground="Black" 
                               Style="{StaticResource PhoneTextExtraLargeStyle}"/>
                    <TextBlock Text="{Binding Path=XXXX}" 
                               TextWrapping="Wrap" 
                               Foreground="Black" 
                               Margin="14,-6,0,0" 
                               Style="{StaticResource PhoneTextSubtleStyle}"/>
                </StackPanel>
            </RadioButton>
        </ContentControl>
    </DataTemplate>
</LongListSelector.ItemTemplate>
