Как изменить ширину label

I’m trying to allow user to resize a label (the control, not the font) before printing it.

For this I’m using a LabelPrint class and I’ve set AutoSize property to false. I already made a code that would adjust font size to my label size. But I can’t change the label size… Thanks for help, here’s the code.

class LabelPrint : Label
{

    public LabelPrint()
    {
        this.ResizeRedraw = true;
        this.AutoSize = false;
        this.TextAlign = ContentAlignment.MiddleCenter;
        this.Font = new Font(this.Font.FontFamily, 12);
        this.SizeChanged += new EventHandler(this.SizeLabelFont);
    }

    protected override void WndProc(ref Message m)
    {
        base.WndProc(ref m);
        if (m.Msg == 0x84)
        {  // Trap WM_NCHITTEST
            var pos = this.PointToClient(new Point(m.LParam.ToInt32()));
            if (pos.X >= this.Size.Width - grab && pos.Y >= this.Size.Height - grab)
                m.Result = new IntPtr(17);  // HT_BOTTOMRIGHT
        }
    }
    private const int grab = 16;


    public void SizeLabelFont(object sender, EventArgs e)
    {
        // Only bother if there's text.
        string txt = this.Text;
        if (txt.Length > 0)
        {
            int best_size = 100;

            // See how much room we have, allowing a bit
            // for the Label's internal margin.
            int wid = this.DisplayRectangle.Width - 3;
            int hgt = this.DisplayRectangle.Height - 3;

            // Make a Graphics object to measure the text.
            using (Graphics gr = this.CreateGraphics())
            {
                for (int i = 1; i <= 100; i++)
                {
                    using (Font test_font =
                        new Font(this.Font.FontFamily, i))
                    {
                        // See how much space the text would
                        // need, specifying a maximum width.
                        SizeF text_size =
                            gr.MeasureString(txt, test_font);
                        if ((text_size.Width > wid) ||
                            (text_size.Height > hgt))
                        {
                            best_size = i - 1;
                            break;
                        }
                    }
                }
            }

            // Use that font size.
            this.Font = new Font(this.Font.FontFamily, best_size);
        }
    }
}

I tried to add this in LabelPrint class:

        protected override void OnLayout(LayoutEventArgs levent)
    {
        base.OnLayout(levent);
        base.AutoSize = false;
    }

But I still get the same problem: AutoSize is set to false so when i increase the fontsize, i can’t see all my label.Text but I can’t resize the label itself… I mean with the mouse and ResizeRedraw().

The <label> element specifies a text label for the <input> tag. Since it is an inline element, using the width property alone won’t have any effect. But there are some methods to add width to the <label> tag.

In this tutorial, we’ll demonstrate some examples of controlling the width of the <label> tag by using the display property set to “block” in combination with the width property.

• Usa a <form> element.
• Place the <label> tag with the for attribute and the <input> tag with the id, name, and type attributes inside the <form> element.

<form>
  <label for="name">Enter your  name:</label>
  <input id="name" name="name" type="text" />
</form>

• Set the display to “block”.
• Specify the width.

label {
  display: block;
  width: 130px;
}

Example of adding width to the <label> tag using the «block» value of the display property:

<!DOCTYPE html>
<html>
  <head>
    <title>Title of the document</title>
    <style>
      label {
        display: block;
        width: 130px;
      }
    </style>
  </head>
  <body>
    <form>
      <label for="name">Enter your name:</label>
      <input id="name" name="name" type="text" />
    </form>
  </body>
</html>

Result

Let’s see another example where we use the display property set to “inline-block”.

Example of adding width to the <label> tag using the «inline-block» value of the display property:

<!DOCTYPE html>
<html>
  <head>
    <title>Title of the document</title>
    <style>
      label {
        display: inline-block;
        width: 150px;
      }
    </style>
  </head>
  <body>
    <form>
      <label for="name">Enter your name:</label>
      <input id="name" name="name" type="text" />
    </form>
  </body>
</html>
