Answer 1

This problem is caused because the ScrollViewer doesn't know how much space it can take up before it needs to scroll and so takes up infinite space and therefore doens't need to scroll it's content. The bounce you are seeing is what happens when you try to move beyond the end of the scrollviewers container.
You could probably solve this by removing the RowDefinitions from LayoutRoot as it's the only item in the grid.
Currently it's in a row which can grow as large as it needs to (that's what setting the row height to "Auto" means). This is regardless of the grid space. You need to limit the amout of space the ScrollViewer can occupy so it knows it needs to scroll it's content.

Answer 2

There are a couple things you need to change here to get it to work correctly. First of all, your ScrollViewer really should be within the grid. Second of all, get rid of the Height on your grid. It winds up looking like this:
<!--LayoutRoot is the root grid where all page content is placed-->
<Grid x:Name="LayoutRoot" Background="#FF1FB0DB">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<!--ContentPanel - place additional content here-->
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0" >

TextWrapping="Wrap">
