Change the style of content dialog button in windows phone universal application

Question

I have this content dialog box defined inside my xaml:

    <ContentDialog x:Name="AlertMessage" Background="#363636" IsSecondaryButtonEnabled="True" SecondaryButtonText="Cancel"  IsPrimaryButtonEnabled="True" PrimaryButtonText="Ok" >
        <ContentDialog.Content>
            <StackPanel Name="rootStackPanel" Height="Auto"  >
                <StackPanel Margin="0">
                    <StackPanel Margin="0,0,0,10" Orientation="Horizontal">
                        <TextBlock x:Name="HeadingText" x:FieldModifier="public" Style="{StaticResource ApplicationMessageBoxHeadingStyle}" Text="Alert"  />
                        <Image Margin="10,05,0,0" Source="/Assets/Images/alert.png" Width="35"></Image>
                    </StackPanel>
                    <TextBlock x:FieldModifier="public" x:Name="ContentText" Style="{StaticResource ApplicationMessageBoxErrorStyle}" Text="Are you sure you want to log off ?" />
                </StackPanel>
            </StackPanel>
        </ContentDialog.Content>
    </ContentDialog>

And I'm calling it like this:

private void AppBarButton_Click(object sender, RoutedEventArgs e)
    {
        MessageBox();
    }
    private async void MessageBox()
    {
        ContentDialogResult LogoutDialog = await AlertMessage.ShowAsync();

        if (LogoutDialog == ContentDialogResult.Primary)
        {
            this.Frame.Navigate(typeof(MainPage));
        }
        else
        {
            // User pressed Cancel or the back arrow.
            // Terms of use were not accepted.
        }

    }

Problem: is that my app have a style for all the buttons in my applications. And I want to apply same styles to the primary and secondary buttons of that dialog box too. And I am unable to figure out how to Achieve this. Is it possible to apply styles to these buttons?
