I think you are confusing "drawing" with the "editable" part.

It sounds like you just want to use a TextBox. A "basic" demonstration:

private Bitmap bmp = new Bitmap(256, 256);

private void Form1_Load(object sender, EventArgs e)
{
  pictureBox1.Image = bmp;
}

private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
  TextBox txt = new TextBox();
  txt.Location = e.Location;
  txt.Width = 120;
  txt.Leave += new EventHandler(txt_Leave);
  pictureBox1.Controls.Add(txt);
}

void txt_Leave(object sender, EventArgs e)
{
  using (Graphics g = Graphics.FromImage(bmp))
  {
    g.DrawString(((TextBox)sender).Text, ((TextBox)sender).Font, Brushes.Black, ((TextBox)sender).Location);
  }
  ((TextBox)sender).Leave -= new EventHandler(txt_Leave);
  pictureBox1.Controls.Remove((TextBox)sender);
  ((TextBox)sender).Dispose();
  pictureBox1.Invalidate();
}

@rainbower And the error is? This was just a basic example of the functionality I think you were trying to achieve based on your post and your comments. – LarsTech Sep 08 '11 at 18:48
No.Check the part 'txt.location=e.Location' – rainbower Sep 08 '11 at 18:51
@rainbower What error are you getting? My code is simply putting a textbox at the location where you are mouse clicking in the picturebox. – LarsTech Sep 08 '11 at 18:56
txt.Location cannot be assigned to e.location – rainbower Sep 08 '11 at 18:58

But in your code the only way to actually draw the text from textBox is to change focus on something else (e.g. by Tab key).
