Hi,

Please check the codes following:

using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Diagnostics;
public class myTextbox : System.Windows.Forms.TextBox
{

private System.Drawing.Color m_BorderColor = System.Drawing.Color.Red;
public System.Drawing.Color GetBorderColor()
{

return this.m_BorderColor;

}

public bool SetBorderColor(System.Drawing.Color clrBorder)
{

this.m_BorderColor = clrBorder;

this.Invalidate();

}

protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);

Pen penBorder = new Pen(this.GetBorderColor(), 1);

Rectangle rectBorder = new Rectangle(e.ClipRectangle.X, e.ClipRectangle.Y, e.ClipRectangle.Width - 1, e.ClipRectangle.Height - 1);

e.Graphics.DrawRectangle(penBorder, rectBorder);

}

}

Best Regards,

Damon

First,

if you want no border then why do you want to change the border color?

If you want to change color then you need to set border style from none to some other value. may be Solid.

Then you can change the border color.

It does not have BorderColor properties. I can only set as below: How to do then??

 this.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle;

txtbox.BorderStyle = BorderStyle.Solid;

txtbox.BorderColor=System.Drawing.ColorTranslator.FromHtml("#0000A0");

OR

txtbox.BorderColor = System.Drawing.Color.Blue;
