How to remove image cropping in picturebox?

Question

C++ / C#

There is a picturebox in which a picture is loaded on button click and another 90 degree rotation on click

pictureBox1.Image.RotateFlip(RotateFlipType.Rotate90FlipNone);
            pictureBox1.Refresh();

And everything seems to be fine, but when you rotate a widescreen picture on its side, it is cut off.
How to deal with it?

Should help

pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
