Removing dynamically created controls in C#

Question

I have a program that adds a series of \"blips\" to a graph:

PictureBox blip = new PictureBox();
blip.Location = new Point(blipHours, blipAltitude);
blip.Siz         


        

Answer 1

This will remove all of the PictureBox controls from the particular container (i assume a graph in your case).

 for (int i = this.Controls.Count - 1; i >= 0; i--)
            {
                PictureBox control = this.Controls[i] as PictureBox;
                if (control == null)
                    continue;

                control.Dispose();
            }
