[issue] overidding onPaint textbox to make lines causes problems

[giddy]

hi when i run this class i made here , this is what it looks like
without text - http://gidsfiles.googlepages.com/LinedTextBox_1.jpg
WITH TEXT (heres the issue) -
http://gidsfiles.googlepages.com/Lin...x_withText.jpg

The text turns BOLD and the lines kinda get erased because of the text.

perhaps i could overide or handle the onKeydown or somethin and
intercept the text to be entered and then draw it myself. Any
suggestions???? ????

this is the code :

using System;
using System.Collecti ons.Generic;
using System.Text;
using System.Drawing;

namespace Linedtextbox
{
class LinedTextBox : System.Windows. Forms.TextBox
{
public LinedTextBox(): base()
{
Multiline = true;

SetStyle(System .Windows.Forms. ControlStyles.U serPaint,true);
}
protected override void
OnPaint(System. Windows.Forms.P aintEventArgs e)
{
int txtHeight = Convert.ToInt32 (Font.GetHeight ()) + 3;
Pen thePen = new Pen(Color.Black );
for (int i = txtHeight; i < Height ; i += txtHeight)
{
e.Graphics.Draw Line(thePen, 0, i, this.Width, i);
}

base.OnPaint(e) ;
}
}
}

Call base onPaint first as this is drawing over your work. Call it first,
then you will be drawing lines over its results.

good thinking , i really hoped it would work but it did'nt work.

Also , if i type text and then cause a repaint (min the wndow , then
restore it) ... the text turns invsible , and the lines show .. but
then when i select the text . . ... poof! go the lines again , like in
the picture!

hey i figured it out:

hey! . .i got it!!!!! .. .

1. Raise a OnPaint manually from WndProc()
2. Keep causing a repaint everytime text is typed!

using System;
using System.Collecti ons.Generic;
using System.Text;
using System.Drawing;

namespace Linedtextbox
{
class LinedTextBox : System.Windows. Forms.TextBox
{
public LinedTextBox(): base()
{
Multiline = true;
}
protected override void WndProc(ref
System.Windows. Forms.Message m)
{
if (m.Msg == 0x00f)
{
// raise the paint event
base.WndProc(re f m);
Graphics graphic = base.CreateGrap hics();
OnPaint(new
System.Windows. Forms.PaintEven tArgs(graphic, base.ClientRect angle));
graphic.Dispose ();
}
else
base.WndProc(re f m);
}
protected override void OnTextChanged(E ventArgs e)
{
Graphics graphic = base.CreateGrap hics();
OnPaint(new System.Windows. Forms.PaintEven tArgs(graphic,
base.ClientRect angle));
graphic.Dispose ();
base.OnTextChan ged(e);
}
protected override void
OnPaint(System. Windows.Forms.P aintEventArgs e)
{
base.OnPaint(e) ;
int txtHeight = Convert.ToInt32 (Font.GetHeight ()) + 1;
Pen thePen = new Pen(Color.Black );
for (int i = txtHeight; i < Height ; i += txtHeight)
{
e.Graphics.Draw Line(thePen, 0, i, this.Width, i);
}
}
}
}
