I can't add a PNG image that contains alpha chanel into a picturebox dynamically by code because it always replace the transparent area with the black color. Is there a way to do it?
Have you tried setting the back color of the control to transparent?

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.
Good afternoon!
I have several user controls, each one with a picture box containing an image. A user control represents the backgroud and the other two are elements that must be overlayed.
pictureBox_background.BackColor = Color.Black;
pictureBox_A.BackColor = Color.Transparent;
pictureBox_background.Controls.Add(pictureBox_A);
pictureBox_background.Controls.Add(pictureBox_B);
pictureBox_B.SendToBack();
pictureBox_A.BringToFront();
With this code I get the picturebox A is over picturebox B, but I can not make the background of the element A is the image of the picturebox B. The pictureBox A reaches the background picturebox, and it's background is the black color of the background picturebox.
That is, the transparency of picturebox_A don't shows the picturebox_B, shows the black background, without showing the image of the medium (picturebox_B).
It's a little hard to explain. I hope it was understood.
Thanks in advance!
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.
I'm displaying a .bmp file in a Form.
Is there any way to render the color black as transparent?
You could try myBitmap.MakeTransparent(Color.Black)
How can I put a transparent PictureBox on another PictureBox?
One transparent PictureBox works on my form but i can not put a transparent PictureBox over another PictureBox.
Here is a picture from my problem.
You need to call Control.BringToFront on the PictureBox you want to be in front (on top).
