List of labels does not display in Picture Box

I have a problem with Labels in VisulaStudio. The version of VisualStudio I use is 2012.

The problem is, I need to show a grid and label the lines. The code I wrote seams identical to the solution of a similar problem here. It doesn't give me any compiler errors, but the labels still do not display in the pictureBox.

private void aResize()
{
       Size clientSize = this.ClientSize;
       int hToDraw, wToDraw;
       hToDraw = clientSize.Height - 2 * marginOfTab;
       wToDraw = clientSize.Width - 2 * marginOfTab;
       tabControl1.Size = new Size(wToDraw, hToDraw);
       piB1.Size = new Size(wToDraw, hToDraw);
       piB1.Image = new Bitmap(piB1.Size.Width, piB1.Size.Height);
       using (Graphics g = Graphics.FromImage(piB1.Image))
       {
           g.FillRectangle(new SolidBrush(Color.LightGray), 0, 0, W, H);
           Pen gridPen = new Pen(Color.White, 1f);
           int hDrawingStep = hToDraw / 10 -1;
           int wDrawingStep = wToDraw / 10 -1;
           for (int local = 1; local < 11; local++)
           {
           g.DrawLine(gridPen, 0,  hDrawingStep*local, wToDraw, hDrawingStep*local);     //horizontal axix
           g.DrawLine(gridPen, wDrawingStep*local, 0, wDrawingStep*local , hToDraw);     //vertical axis
           Label localLabel = new Label();
           localLabel.Name = "la" + local;
           localLabel.Visible = true;
           localLabel.Text = (local*100).ToString();
           localLabel.Location = new Point((int)local*hDrawingStep, (int)10);
           labelList.Add(localLabel);
           }
       }
}

All variables which are not declared in the code above are declared earlier. I didn't want to paste in too much. Thanks for any suggestion.

You don't set any parent for your localLabel, so how could it be rendered? Try this right before adding your localLabel to your labelList:

//...
localLabel.Parent = piB1;
labelList.Add(localLabel);
