Label word wrapping

Question

Is there a way to do a word wrap in a .NET label control?

I know there is an alternate way of using a TextBox, make property BorderStyle to none, property ReadOnly to true and set property WordWrap and property Multiline to true.

Is there something for a label?

I don't think there is, but been quite a while since I did WinForms. — Eric J., Mar 01 '12 at 00:58

Change your maximum size,

label1.MaximumSize = new Size(100, 0);

And set your autosize to true.

label1.AutoSize = true;

That's it!

You may need `using System.Drawing;` too. – Appulus Dec 13 '14 at 13:48

Agree, this is the best and easier to implement answer, just tested it and works perfect – nizx Jun 17 '15 at 17:08
This seem like too magic to me... Also (and more obscure), you need to have autosize Off before doing this. – RSinohara Sep 06 '15 at 22:01

Change this to label1.MaximumSize = new System.Drawing.Size(100, 0); And this works. – user1531040 Dec 01 '15 at 12:52
For me, this causes other controls to get clipped by the container despite it also having the AutoSize property. – Edwin Aug 15 '18 at 10:30
This works also in the Designer – Roland Sep 19 '18 at 09:40

Just set Label AutoSize property to False. Then the text will be wrapped and you can re-size the control manually to show the text.

Refer to Automatically Wrap Text in Label. It describes how to create your own growing label.

Here is the full source taken from the above reference:

using System;
using System.Text;
using System.Drawing;
using System.Windows.Forms;

public class GrowLabel : Label {
  private bool mGrowing;
  public GrowLabel() {
    this.AutoSize = false;
  }
  private void resizeLabel() {
    if (mGrowing) return;
    try {
      mGrowing = true;
      Size sz = new Size(this.Width, Int32.MaxValue);
      sz = TextRenderer.MeasureText(this.Text, this.Font, sz, TextFormatFlags.WordBreak);
      this.Height = sz.Height;
    }
    finally {
      mGrowing = false;
    }
  }
  protected override void OnTextChanged(EventArgs e) {
    base.OnTextChanged(e);
    resizeLabel();
  }
  protected override void OnFontChanged(EventArgs e) {
    base.OnFontChanged(e);
    resizeLabel();
  }
  protected override void OnSizeChanged(EventArgs e) {
    base.OnSizeChanged(e);
    resizeLabel();
  }
}

I am trying to add a new property to existing label, like AutoSize, something like IsWordWrap=true. Any thoughts? so that i can give LabelName.IsWordWrap=true; — Sharpeye500, Mar 01 '12 at 01:22
TextRenderer.MeasureText in my case gave wrong size. To make everything perfect you need also override OnPaint and draw text like this: `TextRenderer.DrawText(e.Graphics, this.Text, this.Font, new Rectangle(0, 0, this.Width, Int32.MaxValue), ForeColor, TextFormatFlags.WordBreak);` — user1561713, Nov 09 '16 at 14:20

Ironically, turning off AutoSize by setting it to false allowed me to get the label control dimensions to size it both vertically and horizontally which effectively allows word-wrapping to occur.

If you open the dropdown for the Text property in Visual Studio, you can use the enter key to split lines. This will obviously only work for static text unless you know the maximum dimensions of dynamic text.

Thanks! This is exactly what I was looking for (how to split lines in the designer). – ehambright Feb 25 '16 at 18:59

If you want some dynamic sizing in conjunction with a word-wrapping label you can do the following:

Put the label inside a panel

Handle the ClientSizeChanged event for the panel, making the label fill the space:

private void Panel2_ClientSizeChanged(object sender, EventArgs e)
{
    label1.MaximumSize = new Size((sender as Control).ClientSize.Width - label1.Left, 10000);
}

Set Auto-Size for the label to true
Set Dock for the label to Fill

You can use a TextBox and set multiline to true and canEdit to false .

multiline and canEdit aren't actual properties on TextBox. – Stealth Rabbi Sep 21 '16 at 15:17
