int num1 = Form.ActiveForm.Location.X + pnlDrawingArea.Location.X + 30;
int num2 = Form.ActiveForm.Location.Y + pnlDrawingArea.Location.Y + 40;
//Create Rectangle Box
if (drawRect == "Yes")
{
  if (i > -1)
  {
    p1 = new Panel();
    p1.Name = "Rect" + i.ToString();
    p1.AllowDrop = true;
    p1.Location = new Point(MousePosition.X - num1, MousePosition.Y - num2);
    p1.BackColor = Color.Red;
    p1.Click += new EventHandler(p1_Click);
    p1.MouseDown += new MouseEventHandler(p1_MouseDown);
    p1.MouseMove += new MouseEventHandler(p1_MouseMove);
    p1.MouseUp += new MouseEventHandler(p1_MouseUp);
    p1.DragEnter += new DragEventHandler(p1_DragEnter);
    p1.DragDrop += new DragEventHandler(p1_DragDrop);
    p1.GotFocus += new EventHandler(p1_GotFocus);
    p1.LostFocus += new EventHandler(p1_LostFocus);
    this.pnlDrawingArea.Controls.Add(p1);
    
    if (p1.CanFocus)
    {
      p1.Focus();
    }
    
    i++;
  }
  drawRect = "No";

}

void p1_DragDrop(object sender, DragEventArgs e)
{
  p1 = (Panel)sender;
  if (flag == "Yes")
  {
    int num1 = Form.ActiveForm.Location.X + pnlDrawingArea.Location.X + p1.Location.X;
    int num2 = Form.ActiveForm.Location.Y + pnlDrawingArea.Location.Y + p1.Location.Y + 40;
    pnlTblNo = new Button();
    pnlTblNo.Name = "RectTbl" + i.ToString();
    pnlTblNo.AllowDrop = true;
    pnlTblNo.Text = e.Data.GetData(DataFormats.Text).ToString();
    pnlTblNo.Height = 28;
    pnlTblNo.Width = 30;
    pnlTblNo.BackColor = Color.SeaShell;
    //pnlTblNo.Click += new EventHandler(pnlTblNo_Click);
    pnlTblNo.MouseDown += new MouseEventHandler(pnlTblNo_MouseDown);
    pnlTblNo.MouseUp += new MouseEventHandler(pnlTblNo_MouseUp);
    pnlTblNo.MouseMove += new MouseEventHandler(pnlTblNo_MouseMove);
    pnlTblNo.LostFocus += new EventHandler(pnlTblNo_LostFocus);
    pnlTblNo.Anchor = (AnchorStyles.Left | AnchorStyles.Top);
    pnlTblNo.Location = new Point(MousePosition.X - num1, MousePosition.Y - num2);
    this.p1.Controls.Add(pnlTblNo);
    flag = "No";
  }
  
  if (p1.CanFocus)
  {
    p1.Focus();
  }
}

void pnlTblNo_MouseMove(object sender, MouseEventArgs e)
{
  if (Dragging)
  {
    num1 = Form.ActiveForm.Location.X + pnlDrawingArea.Location.X + p1.Location.X+10;
    num2 = Form.ActiveForm.Location.Y + pnlDrawingArea.Location.Y + p1.Location.Y+30;
    num3 = Form.ActiveForm.Location.X + pnlDrawingArea.Location.X + p1.Location.X + 10 + p1.Width;
    num4 = Form.ActiveForm.Location.Y + pnlDrawingArea.Location.Y + p1.Location.Y + 30+p1.Height;
    
    if(MousePosition.X>num3||MousePosition.Y>num4)
    {
      MessageBox.Show("Please Select panel");
    }
    else
    {
      pnlTblNo.Location = new Point(MousePosition.X - num1, MousePosition.Y - num2);
    }

  }
}
