I am making an application in C# .NET. I have 8 picture boxes in it. I used PNG images with transparent background but in my form it is not transparent when it comes above another image.

I am using Visual Studio 2012. This is a screenshot of my form:

One way to do this is by changing the parent of the overlapping picture box to the PictureBox over which it is lapping. Since the Visual Studio designer doesn't allow you to add a PictureBox to a PictureBox, this will have to be done in your code (Form1.cs) and within the Intializing function:

public Form1(){ InitializeComponent(); pictureBox7.Controls.Add(pictureBox8); pictureBox8.Location = new Point(0, 0); pictureBox8.BackColor = Color.Transparent;}

Just change the picture box names to what ever you need. This should return:

Try using an ImageList

ImageList imgList = new ImageList;imgList.TransparentColor = Color.White;

Load the image like this:

picturebox.Image = imgList.Images[img_index];

I've had a similar problem like this.You can not make Transparent picturebox easily such as picture that shown at top of this page, because .NET Framework and VS .NET objects are created by INHERITANCE! (Use Parent Property).

I solved this problem by RectangleShape and with the below code I removed background,if difference between PictureBox and RectangleShape is not important and doesn't matter, you can use RectangleShape easily.

private void CreateBox(int X, int Y, int ObjectType){ ShapeContainer canvas = new ShapeContainer(); RectangleShape box = new RectangleShape(); box.Parent = canvas; box.Size = new System.Drawing.Size(100, 90); box.Location = new System.Drawing.Point(X, Y); box.Name = "Box" + ObjectType.ToString(); box.BackColor = Color.Transparent; box.BorderColor = Color.Transparent; box.BackgroundImage = img.Images[ObjectType];// Load from imageBox Or any resource box.BackgroundImageLayout = ImageLayout.Stretch; box.BorderWidth = 0; canvas.Controls.Add(box); // For feature use }

One fast solution is set image property for image1 and set backgroundimage property to imag2, the only inconvenience is that you have the two images inside the picture box, but you can change background properties to tile, streched, etc. Make sure that backcolor be transparent.Hope this helps

Just use the Form Paint method and draw every Picturebox on it, it allows transparency :

 private void frmGame_Paint(object sender, PaintEventArgs e) { DoubleBuffered = true; for (int i = 0; i < Controls.Count; i++) if (Controls[i].GetType() == typeof(PictureBox)) { var p = Controls[i] as PictureBox; p.Visible = false; e.Graphics.DrawImage(p.Image, p.Left, p.Top, p.Width, p.Height); } }
