you don't dispose of the Graphics object

drawing to the textbox in this way is only visible as long as the textbox isn't redrawn.

Well, last time I checked my GC wasn't on vacation! My graphics objects are local variables, they will be disposable once the call to the handler is over

using (Graphics g = textBox.CreateGraphics())
{
}

Unfortunately, no! This is not a webpage where the user may click refresh, and almost all the causes of paint are mouse involved. Once the mouse is out of the box, it doesn't matter!!

you're not calling Dispose()

just move another window over the textbox (or part of it) and you'll see what I mean.

How could you do that without moving the mouse out of the textbox first?

private bool DrawBox = false;

private void textBox1_MouseEnter(object sender, EventArgs e)
{
    Drawbox = true;
}

private void textBox1_MouseLeave(object sender, EventArgs e)
{
    Drawbox = false;
}

//now draw the Box according to input focus

private void textBox1_Enter(object sender, EventArgs e)
{
    Drawbox = true;
}

private void textBox1_Leave(object sender, EventArgs e)
{
    Drawbox = false;
}

private void textBox1_Paint(object sender, EventArgs e)
{
    Graphics g = textBox1.CreateGraphics();
    if(DrawBox)    
        g.DrawRectangle(new Pen(Brushes.Red, 3), new Rectangle(0, 0, textBox1.Width - 5, textBox1.Height - 5));
    else
        g.DrawRectangle(new Pen(Brushes.White, 3), new Rectangle(0, 0, textBox1.Width - 5, textBox1.Height - 5));
    g.Dispose();
}
