Make portion of a Label's Text to be styled bold

Question

Is there any way to make a part of a label.text to be bold?

label.text = "asd" + string;

Would like the string portion to be bold.

Is possible, how can this be done?

Answer 1

The following class illustrates how to do it by overriding OnPaint() in the Label class of WinForms. You can refine it. But what I did was to use the pipe character (|) in a string to tell the OnPaint() method to print text before the | as bold and after it as normal text.

class LabelX : Label {     protected override void OnPaint(PaintEventArgs e) {         Point drawPoint = new Point(0, 0);          string[] ary = Text.Split(new char[] { '|' });         if (ary.Length == 2) {             Font normalFont = this.Font;              Font boldFont = new Font(normalFont, FontStyle.Bold);              Size boldSize = TextRenderer.MeasureText(ary[0], boldFont);             Size normalSize = TextRenderer.MeasureText(ary[1], normalFont);              Rectangle boldRect = new Rectangle(drawPoint, boldSize);             Rectangle normalRect = new Rectangle(                 boldRect.Right, boldRect.Top, normalSize.Width, normalSize.Height);              TextRenderer.DrawText(e.Graphics, ary[0], boldFont, boldRect, ForeColor);             TextRenderer.DrawText(e.Graphics, ary[1], normalFont, normalRect, ForeColor);         }         else {              TextRenderer.DrawText(e.Graphics, Text, Font, drawPoint, ForeColor);                         }     } } 

Here's how to use it:

LabelX x = new LabelX(); Controls.Add(x); x.Dock = DockStyle.Top; x.Text = "Hello | World";        

Hello will be printed in bold and world in normal.

WebForms

Use Literal control, and add a <b> tag around the part of the text you want:

_myLiteral.Text = "Hello <b>big</b> world";

Winforms

Two options:

1. Put two labels side by side (far easier)
2. Subclass Label and do your own custom drawing in the OnPaint() method.

The second choice has been answered already.

Answer 3

WinForms doesn't allow you to do that.
