Word wrap for a label in Windows Forms

Question

How can we get word wrap functionality for a label in Windows Forms?

I placed a label in a panel and added some text to label dynamically. But it exceeds the panel length. How can I solve this?

Answer 1

In my case (label on a panel) I set label.AutoSize = false and label.Dock = Fill. And the label text is wrapped automatically.

Answer 2

If you really want to set the label width independent of the content, I find that the easiest way is this:

• Set autosize true
• Set maximum width to how you want it
• Set minimum width identically

Now the label is of constant width, but it adapts its height automatically.

Then for dynamic text, decrease the font size. If necessary, use this snippet in the sub where the label text is set:

If Me.Size.Height - (Label12.Location.Y + Label12.Height) < 20 Then
    Dim naam As String = Label12.Font.Name
    Dim size As Single = Label12.Font.SizeInPoints - 1
    Label12.Font = New Font(naam, size)
End If

This helped me in my Form called InpitWindow: In Designer for Label:

AutoSize = true;
Achors = Top, Left, Right.

private void InputWindow_Shown(object sender, EventArgs e) {
    lbCaption.MaximumSize = new Size(this.ClientSize.Width - btOK.Width - btOK.Margin.Left - btOK.Margin.Right -
        lbCaption.Margin.Right - lbCaption.Margin.Left, 
        Screen.GetWorkingArea(this).Height / 2);
    this.Height = this.Height + (lbCaption.Height - btOK.Height - btCancel.Height);
    //Uncomment this line to prevent form height chage to values lower than initial height
    //this.MinimumSize = new Size(this.MinimumSize.Width, this.Height);
}
//Use this handler if you want your label change it size according to form clientsize.
private void InputWindow_ClientSizeChanged(object sender, EventArgs e) {
    lbCaption.MaximumSize = new Size(this.ClientSize.Width - btOK.Width - btOK.Margin.Left * 2 - btOK.Margin.Right * 2 -
        lbCaption.Margin.Right * 2 - lbCaption.Margin.Left * 2,
        Screen.GetWorkingArea(this).Height / 2);
}

Whole code of my form

1. Put the label inside a panel

2. 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);
   }
   

3. Set Auto-Size for the label to true

4. Set Dock for the label to Fill
