I added a ScrollBar to the control and to the Controls property of the Panel.

I thought of clearing the Controls property of the Panel and always just adding the visible PictureBoxes (they all are stored in an extra collection), determining which ones are visible by Panel and PictureBox size.Though, this would need calculations and have to be pixel-exact, if possible I dould like to avoid this and use a more elegant way.

g.DrawImage(resource, new Rectangle(0, 0, 32, 32), 
   new Rectangle(32 * i, 32 * k, 32, 32), GraphicsUnit.Pixel);

for (int i = 0; i <= width; i++)
            {
                for (int k = 0; k <= height; k++)
                {
                    if (i == 7 && k == 15)
                    {
                        this.Text = this.Text;
                    }
                    g = Graphics.FromImage(memory);

                    coordinate = new Point(i, k);
                    pictureboxes.Add(coordinate, new PictureBox());
                    pictureboxes[coordinate].Height = 32;
                    pictureboxes[coordinate].Width = 32;
                    pictureboxes[coordinate].Visible = true;
                    pictureboxes[coordinate].Anchor = AnchorStyles.Left | AnchorStyles.Top;
                    pictureboxes[coordinate].BorderStyle = BorderStyle.FixedSingle;
                    pictureboxes[coordinate].Margin = new Padding(0);

                    pictureboxes[coordinate].Location = new Point(32 * i, 32 * k);

                    pictureboxes[coordinate].MouseDown += new MouseEventHandler(OnLeftDown);
                    pictureboxes[coordinate].MouseDown += new MouseEventHandler(OnRightClick);

                    g.DrawImage(resource, new Rectangle(0, 0, 32, 32), 
                        new Rectangle(32 * i, 32 * k, 32, 32), GraphicsUnit.Pixel);
                    
                    pictureboxes[coordinate].Image = new Bitmap(memory, new Size(32, 32));

                    FLP_Resource.Controls.Add(pictureboxes[coordinate]);
                }

what that mean ?

So that I ensure I have only 1 PictureBox for each coordinate.In a List I could end up having with 2 PictureBoxes having the same coordiantes.

When you assign the Image property of a PictureBox, you can only assign the whole image, in my case that would be the whole 256x2000 pixel source image.What I want is to split that image into 32x32 pixel tiles and assign each of these tiles to a different PictureBox, so you can click on and select each separately.Then you can paste the 32x32 tiles and build your map with them.

2000 cant be divide by 32, your image must have 2048 height if you gonna tile of 32 x 32

Xmen wrote:

Cursor Position : 35, 126
Nearest Tile Position(by rounding) : 32, 96

An advice, do not set Image in Image property, use BackgroundImage instead, therefore you can use BackgroundImageLayout and avoid lots of hassles.

pictureboxes[coordinate].BackgroundImageLayout = ImageLayout.Tile;
