Try this:

public partial class Form1 : Form
{
        private void button1_Click(object sender, EventArgs e)
        {
            Util.PlaceControlToContainer(this.button1, this.panel2);
        }
}
public static class Util
{
   public static void PlaceControlToContainer(Control control, Control container)
   {
       lock (control)
       {
          if (control.Parent != null)
          {
              control.Parent.Controls.Remove(control);
          }
          container.Controls.Add(control);
       }
   }
}

Should be fairly easy:

  1. Get the list of controls from your parent control.
  2. Call the Remove function on that list to remove your control.

So something like this:

myListControl.Controls.Remove(myControlToRemove);
