Drawing a Border for a textbox

[Murali Valluri]

I have tried the following, which draws the border but clears the Text
when the control does not have focus.
Please help.
----------------------------------------------------------
1. Set the ControlStyle to "UserPaint" in the constructor:

public MyTextBox()
{
// This call is required by the Windows.Forms Form Designer.
this.SetStyle(ControlStyles.UserPaint,true);
InitializeComponent();

// TODO: Add any initialization after the InitForm call
}

2. Add the following code to the overrided OnPaint method.

protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
int borderWidth = 1;
Color borderColor = Color.Blue;

ControlPaint.DrawBorder(e.Graphics, e.ClipRectangle, borderColor,
borderWidth, ButtonBorderStyle.Solid, borderColor, borderWidth,

ButtonBorderStyle.Solid, borderColor, borderWidth,
ButtonBorderStyle.Solid,

borderColor, borderWidth, ButtonBorderStyle.Solid);
}

Hmm, Interesting.
As soon as you set
this.SetStyle(ControlStyles.UserPaint,true)
you have to take over all aspects of drawing, including text output.
So you have to
e.Graphics.DrawString(Text,this.Font,br,0,0);
But when user edit text it looks incosistens, and when user leave it, no
repaint is called. I see that .net control is strange mix of wrappers of
windows native gui calls.
