PictureBox.BringToFront(); Not working with transparency

I need to put a picturebox above another picture box, the picturebox on top is a png file with a transparent background but when trying to use Picturebox.BringToFront(); the picturebox below is replaced with what is in the background of the form.
I tried to get around this using picturebox.Parent = picturebox2, but I don't want the picturebox to be cut off at the edges of the other picturebox it's on top of.

How to make picturebox transparent when it comes above another image

I am making an application in C#.NET with Visual Studio 2012.
I have a picture in my background form. I have several picture boxes on it. I used .png images with transparent background but in my form it is not transparent when it comes above another image.
Set your picture box back color property to transparent.
pictureBoxTest.BackColor = Color.Transparent;
To further explain, an image with a transparent background will inherit the picture box's background color. You need to set the color to transparent as well to ensure it truly is.

Secondary tile text colour

I know that MSDN states that this is not possible but is there any possible workaround/hack to change the colour of the text on a secondary tile?
The only way to change font color is make text as your background image.
You can do like this:
put textBlock in a grid, change font color.
Render this grid to an image.
then save it to storage.
and set it as background image of tile.
