ok what im getting at:

the extact method you are looking for is DrawString.

you are correct we must reuse, to do that use DrawString, all the wrapping is handled. If you call DrawString, it will wrap the text according to stringAlignment and lineAlignment BUT its not fully implemented yet. MeasureCharacterRanges is - which is what i use for the textbox to get the positions, i then draw each character. What i will do is make sure that DrawString renders like MeasureCharacterRanges. This is a snippet of code to give you the idea:

 

// Convert control settings to a StringFormat

StringFormat format = new StringFormat();

if (RightToLeft == RightToLeft.Yes)

  format.FormatFlags |= StringFormatFlags.DirectionRightToLeft;

if (!Multiline)

  format.FormatFlags |= StringFormatFlags.NoWrap;

if (textAlign == HorizontalAlignment.Left)

  format.Alignment = StringAlignment.Near;

else if (textAlign == HorizontalAlignment.Right)

  format.Alignment = StringAlignment.Far;

else if (textAlign == HorizontalAlignment.Center)

  format.Alignment = StringAlignment.Center;

g.DrawString(Text, Font, bounds, format)
