The problem is due to usage of multiple ScrollViewer; LongListSelector has default scrolling mechanism when items in it exceeds the size of the control, so we dont need to explicitly put a ScrollViewer over LongListSelector.

In your case, there will be two scrollviewers, one from LongListSelector and one which you put explicitly. So scrolling is not happening.

So, Just remove the ScrollViewer from all of your Pivot Items and set the Grid.Row property to the LongListSelector.

I had a similar issue with a ScrollViewer inside a PivotItem. The problem was that the content (a Grid) inside the ScrollViewer was the same height as the PivotItem so there was effectively nothing for the ScrollViewer to scroll. I fixed the problem by making the PivotItem height smaller than the height of the content inside the ScrollViewer.

try to add the code below under your Grid ContentPanel :

<Grid.RowDefinitions>
    <RowDefinition Height="*"/>
</Grid.RowDefinitions>

Actually, your code works fine as I've tested.

If you need further help, you may need to paste your whole xaml.
