                </Grid>
            </Controls:Flyout>
        </Controls:FlyoutsControl>

Maybe you forgot to put your flyout in the flyouts. And you should use Position="Bottom" not VerticalAlignment="Bottom" .

<Grid>
    <ScrollViewer Name="scrlMain"
                    CanContentScroll="True"
                    HorizontalScrollBarVisibility="Auto"
                    VerticalScrollBarVisibility="Auto"
                    VerticalAlignment="Stretch">

        <TextBlock Text="Test"></TextBlock>

    </ScrollViewer>

    <Controls:Flyout Header="Actions"
                        Name="TestFlyout"
                        IsOpen="True"
                        Position="Bottom"
                        Width="990"
                        Theme="Adapt">
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="20*"></ColumnDefinition>
                <ColumnDefinition Width="20*"></ColumnDefinition>
            </Grid.ColumnDefinitions>
            <Button Content="Save"
                    Width="70"
                    Height="30"
                    HorizontalAlignment="Left"
                    Grid.Column="0"></Button>
            <Button Content="Cancel"
                    Width="70"
                    Height="30"
                    HorizontalAlignment="Left"
                    Grid.Column="1"></Button>
        </Grid>
    </Controls:Flyout>

</Grid>

Hope this helps.
