How can I change the border thickness of a Groupbox on a windows form in C#?
Guys
I am using groupbox' in Visual studio. But the Border in the groupbox is to small. I was wondering if there is a way to edit the border by giving it a color or maybe a thicker edge?
As u can see in the image it is very hard to see the border around it.
Can anyone help me with this ?
You can Use This:
using System.Drawing;
using System.Drawing.Drawing2D;
private void Form1_Load(object sender, EventArgs e)
{
myGroupBox myGroupBox = new myGroupBox();
myGroupBox.Text = "GroupBox1";
this.Controls.Add(myGroupBox);
}
public static GraphicsPath CreatePath(float x, float y, float width, float height,
float radius, bool RoundTopLeft, bool RoundTopRight, bool RoundBottomRight, bool RoundBottomLeft)
{
float xw = x + width;
float yh = y + height;
float xwr = xw - radius;
float yhr = yh - radius;
float xr = x + radius;
float yr = y + radius;
float r2 = radius * 2;
float xwr2 = xw - r2;
float yhr2 = yh - r2;
GraphicsPath p = new GraphicsPath();
p.StartFigure();
//Top Left Corner
if (RoundTopLeft)
{
p.AddArc(x, y, r2, r2, 180, 90);
}
else
{
p.AddLine(x, yr, x, y);
p.AddLine(x, y, xr, y);
}
//Top Edge
p.AddLine(xr, y, xwr, y);
//Top Right Corner
if (RoundTopRight)
{
p.AddArc(xwr2, y, r2, r2, 270, 90);
}
else
{
p.AddLine(xwr, y, xw, y);
p.AddLine(xw, y, xw, yr);
}
//Right Edge
p.AddLine(xw, yr, xw, yhr);
//Bottom Right Corner
if (RoundBottomRight)
{
p.AddArc(xwr2, yhr2, r2, r2, 0, 90);
}
else
{
p.AddLine(xw, yhr, xw, yh);
p.AddLine(xw, yh, xwr, yh);
}
//Bottom Edge
p.AddLine(xwr, yh, xr, yh);
//Bottom Left Corner
if (RoundBottomLeft)
{
p.AddArc(x, yhr2, r2, r2, 90, 90);
}
else
{
p.AddLine(xr, yh, x, yh);
p.AddLine(x, yh, x, yhr);
}
//Left Edge
p.AddLine(x, yhr, x, yr);
p.CloseFigure();
return p;
}
class myGroupBox : GroupBox
{
public myGroupBox()
{
base.BackColor = Color.Transparent;
}
[Browsable(false)]
public override Color BackColor

get { return this.backColor; }
set { this.backColor = value; }
}
protected override void OnPaint(PaintEventArgs e)
{
Size tSize = TextRenderer.MeasureText(this.Text, this.Font);
Rectangle borderRect = e.ClipRectangle;
borderRect.Y += tSize.Height / 2;
borderRect.Height -= tSize.Height / 2;
GraphicsPath gPath = CreatePath(0, borderRect.Y, (float)(this.Width - 1), borderRect.Height - 1, 5, true, true, true, true);
e.Graphics.FillPath(new SolidBrush(ActualBackColor), gPath);
e.Graphics.DrawPath(new Pen(Color.Red), gPath);
borderRect.X += 6;
borderRect.Y -= 7;
e.Graphics.DrawString(this.Text, this.Font, new SolidBrush(this.ForeColor), borderRect);
}
