بفرما این همون کلاسه:

کد:

public class ResizeableControl
    {

        private Control mControl;
        private bool mMouseDown = false;
        private EdgeEnum mEdge = EdgeEnum.None;
        private int mWidth = 4;
        private bool mOutlineDrawn = false;

        private enum EdgeEnum
        {
            None,
            Right,
            Left,
            Top,
            Bottom,
            TopLeft
        }

        public ResizeableControl(Control Control)
     {
         mControl = Control;

     }

                    break;
            }

            else
            {

                        //bottom edge
                        c.Cursor = Cursors.HSplit;
                        mEdge = EdgeEnum.Bottom;
                }else{
                        //no edge
                        c.Cursor = Cursors.Default;
                        mEdge = EdgeEnum.None;
                
                }
            }
        }
        private void mControl_MouseLeave(object sender, System.EventArgs e)
        {
            Control c = (Control)sender;
            mEdge = EdgeEnum.None;
            c.Refresh();
        }

    }

فقط کافیه مثلا توی لود فرم یا سازندهش مینویسید :

کد:

ResizeableControl rc = new ResizeableControl(button1);
