Answer 1

well you can do something like this for mouse enter and leave

<Canvas  x:Name="Canvas" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0,9,6,0">
    <Button Canvas.Top="0" Canvas.Left="0" x:Name="button" Width="100" MouseEnter="Butt_OnMouseEnter" Height="200"/>
</Canvas>

and in handler

private void Butt_OnMouseEnter(object sender, MouseEventArgs e)
{
    var position = e.GetPosition(Canvas);
}

now this position is wrt to canvas hence will tell you which side mouse entered or left from..

Answer 2

It should be something like that :

 protected Point TouchStart;
        private void UIElement_OnMouseEnter(object sender, MouseEventArgs e)
        {
            TouchStart = e.GetPosition(this);
            MyButton.Background = Brushes.Red;

        }
    private void UIElement_OnMouseLeave(object sender, MouseEventArgs e)
    {
            var touch = e.GetPosition(this);

        if (touch.X >= (TouchStart.X + 99)) //button width here

        {
            MyButton.Background = Brushes.Aquamarine;
        }
    }

And XAML :

  <Button Width="100" x:Name="MyButton" Height="30" MouseEnter="UIElement_OnMouseEnter" MouseLeave="UIElement_OnMouseLeave" >HoverMe</Button>
