Scrollviewer in UWP app not working - windows-phone-8

Question

I have a page in landscape mode, set in code with the next line:
DisplayInformation.AutoRotationPreferences = DisplayOrientations.LandscapeFlipped | DisplayOrientations.Landscape;
Following is code for full screen mode:
Windows.UI.ViewManagement.ApplicationView view = Windows.UI.ViewManagement.ApplicationView.GetForCurrentView();
view.TryEnterFullScreenMode();
In my scrollviewer, I want to include some dynamically created charts from syncfusion package. I thought this was the problem but after a while, I tried creating some rows in a grid with just textblocks so I could try the scrollviewer and it doesn't work either.
This is all my page content (except page and page.resources content) :
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition Height="auto"/>
<RowDefinition Height="auto"/>
<RowDefinition />
</Grid.RowDefinitions>
<StackPanel Background="{StaticResource AccentBrush}" Grid.Row="0" Margin="0,0,0,10">
<TextBlock Name="Statistic_name" HorizontalAlignment="Center" FontSize="23" Text="Estadísticas"/>
</StackPanel>
<StackPanel Grid.Row="1" Margin="15,0,15,0">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<ComboBox Grid.Column="0" Name="Combo_device" PlaceholderText="Contenedor" SelectionChanged="Combo_device_SelectionChanged" />
<ComboBox Grid.Column="1" Name="Combo_sensor" PlaceholderText="Sensor" />
<ComboBox Grid.Column="2" Name="Combo_number" PlaceholderText="Número" />
<!-- SelectionChanged="Combo_number_SelectionChanged" -->
<Button Name="Show_data" Grid.Column="3" Click="Show_data_Button_Click" Content="Cargar Datos"/>
</Grid>
</StackPanel>
<StackPanel Grid.Row="2">
<ScrollViewer Margin="20,20,20,20" Name="Scroll_container" HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Visible" >
<Grid Name="Stack_panel_scroll_statistics">
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
<RowDefinition />

<RowDefinition />
<RowDefinition />
<RowDefinition />
<RowDefinition />
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock Grid.Row="0">Hola 0</TextBlock>
<TextBlock Grid.Row="1">Hola 1</TextBlock>
<TextBlock Grid.Row="2">Hola 2</TextBlock>
<TextBlock Grid.Row="3">Hola 3</TextBlock>
<TextBlock Grid.Row="4">Hola 4</TextBlock>
<TextBlock Grid.Row="5">Hola 5</TextBlock>
<TextBlock Grid.Row="6">Hola 6</TextBlock>
<TextBlock Grid.Row="7">Hola 7</TextBlock>
<TextBlock Grid.Row="8">Hola 8</TextBlock>
<TextBlock Grid.Row="9">Hola 9</TextBlock>
<TextBlock Grid.Row="10">Hola 10</TextBlock>
<TextBlock Grid.Row="11">Hola 11</TextBlock>
<TextBlock Grid.Row="12">Hola 12</TextBlock>
<TextBlock Grid.Row="13">Hola 13</TextBlock>
<TextBlock Grid.Row="14">Hola 14</TextBlock>
<TextBlock Grid.Row="15">Hola 15</TextBlock>
<TextBlock Grid.Row="16">Hola 16</TextBlock>
<TextBlock Grid.Row="17">Hola 17</TextBlock>
</Grid>
</ScrollViewer>
</StackPanel>
</Grid>
Can somebody tell me where the error is?
I tried by modifying the code a lot and the result is always the same. I thought it was because the content was dynamically created in C# part but after trying with textblocks, it doesn't seem to be the case.

Change the <RowDefinition Height="auto"/> for Grid.Row=2 which encloses your scrollViewer to <RowDefinition Height="*"/> or specify a minimum height for your scrollviewer.
EDIT
Remove Stackpanel also and just simply use a Scrollviewer
