ScrollViewer Issue with StackPanel in Windows Phone 8

I put StackPanel into ScrollViewr, When scrolling to last item it returns back to its old position.

<ScrollViewer Margin="0,0,0,20">
<StackPanel>
  //Textblocks and Textboxes ...
</StackPanel>
</ScrollViewer>

After search i found that: ItemsControl, VirtualizingStackPanel and ScrollViewer height

I changed my code to:

<StackPanel>
  //Textblocks and Textboxes ...
</StackPanel>
<ScrollViewer>
<VirtualizingStackPanel />
 </ScrollViewer>

I can't set CanContentScroll="True" as i can't find it. Also make exception: System.InvalidOperationException: A VirtualizingPanel is not nested in an ItemsControl. VirtualizingPanel must be nested in ItemsControl to get and show items.

What must i do, to enable scrolling without returning back to its old position?

Did you get bounce back effect in the first attempt? Like you couldn't really scroll, it was merely stretched? – Toni Petrina
No, it scroll vertically but once i reach last item and remove my finger it return back to the top again. – Samar ElFwakhry
Can you scroll to the half of the list without auto scroll to the top? – Toni Petrina
Exactly I have 4 textboxes, I enter data at 1st one, I want to scroll to the last to write in it but, it scroll to just 2nd one and can't reach the last. – Samar ElFwakhry
Can you post the full snippet with the surrounding code for the scroll viewer? Not the inside, but the outside XAML. – Toni Petrina
