  If you mean you want to change size of the texbox according to the length of text, then you can try

  Font font = new Font(TextBox1.Font.Name, TextBox1.Font.Size);
  Size s = TextRenderer.MeasureText(TextBox1.Text, font);
  TextBox1.Width = s.Width;

  I would do that however using js/jquery 

  if ($('#TextBox1').val().length > 100) {
    $('#TextBox1').css('width', '500px');
  }  

  Another idea, you can change font size as it is shown at http://web-design-weekly.com/blog/snippets/change-font-size-within-input-field-based-on-length/ 

  Hope this helps.

  You mean you have a box drawn on a picture? If true, read http://msdn.microsoft.com/en-us/library/6xe5hazb.aspx

  Hi Smirnov

  Yes. I mean on an image. The link tells about a method that measures size(on image) of a specified string with specified font. What I need is a method to tell me(measure) font size for a specified box(Size in GDI+) and a specified string that must be drawn into it. It's not difficult to measure font size provided the relation between font size and drawn string is linear. At this point arises another question: Is relation of font size and drawn string linear?

  Thanks

  (measure) font size for a specified box(Size in GDI+)

  If box is a picture, what font size do you mean? The picture has no font. You can draw a text but you define the font by yourself.
