How to display/bind multiple images in only one picturebox?

You have to draw all image to one image for displaying them in single picturebox

That is bit complex you can use mutiple pictureboxes

In following code they are created dynamically according to need:

    // For confirm visibility of all images set

    this.AutoScroll = true;

    string[] list = Directory.GetFiles(@"C:\pictures", "*.jpg");

    PictureBox[] picturebox= new PictureBox[list.Length];

    int y = 0;

    for (int index = 0; index < picturebox.Length; index++)

    {

        this.Controls.Add(picturebox[index]);

        // Following three lines set the images(picture boxes) locations

        if(index % 3 == 0)

            y = y + 150; // 3 images per rows, first image will be at (20,150)

        picturebox[index].Location=new Point(index * 120 + 20, y);

        picturebox[index ].Size = new Size(100,120);

        picturebox[index].Image = Image.FromFile(list[index]);

    }
