C# PictureBox on top of another PictureBox

Question

I want the pbGrade to be on top of pbItemtype (pb = picture box)

 pbItemtype.BackColor = Color.Transparent;

 // Change parent for over         


        

Answer 1

Best approach is to construct the image with overlays off-line in a Bitmap object, then assign that constructed image to the PictureBox for display.

For example like this:

int width = 100;
int height = 100;
Image image = new Bitmap(width, height);

using (var graphics = Graphics.FromImage(image))
{
    graphics.DrawImage(MyApplication.Properties.Resources.ImageItemX, new Rectangle(0, 0, width, height));
    graphics.DrawImage(MyApplication.Properties.Resources.ImageGradeZ, new Rectangle(0, 0, width, height));
}

myPictureBox.SizeMode = PictureBoxSizeMode.Zoom;
myPictureBox.Image = image;

This assumes that ImageItemX and ImageGradeZ are images with a transparent background (for example pngs) imported as project resources under these names.

For example given these resources

the code will produce this:
