Answer 1

Here is example based on default template, with Grid named LayoutRoot.

private void LayoutRoot_Tap(object sender, GestureEventArgs e)
{
    if (e.OriginalSource == LayoutRoot)
        MessageBox.Show("You clicked on LayoutRoot!");
    else
        MessageBox.Show("You clicked on somewhere else!");
}

XAML

<Grid x:Name="LayoutRoot" ... Tap="LayoutRoot_Tap">
