If you mean a ticker/marquee effect (not scrollbars), a WinForms Label will clip text when AutoSize=false and can show ellipsis with AutoEllipsis=true. That solves readability, but not animation. is right that a TextBox with scrollbars is simplest for long, user-controlled text; however, if you want an auto-scrolling banner, animate the label itself rather than rewriting characters as in ’s example (rewriting can cause uneven spacing and high GC pressure for long texts).

WinForms marquee approach: place a Label inside a fixed-width Panel (acts as the viewport), and move the label left on a Timer. This keeps kerning intact and is flicker-free with double buffering.

// Designer: panelViewport (Width fixed, AutoScroll=false), labelTicker (AutoSize=true) inside it.
// Form code:
public partial class Form1 : Form
{
    readonly Timer _timer = new Timer { Interval = 30 }; // ~33 FPS
    public Form1()
    {
        InitializeComponent();
        this.DoubleBuffered = true;               // reduce flicker
        labelTicker.Text = "This is a long message that scrolls smoothly...";
        labelTicker.Left = panelViewport.Width;   // start just off the right edge
        _timer.Tick += (s, e) =>
        {
            labelTicker.Left -= 2;                // speed in px/tick
            if (labelTicker.Right <= 0)           // fully left of viewport
                labelTicker.Left = panelViewport.Width;
        };
        _timer.Start();
    }
}

ASP.NET WebForms/page (client-side) alternative: use a clipped container and CSS animation. This avoids the deprecated <marquee> and works without JavaScript.

<style>
.view { width: 320px; overflow:hidden; white-space:nowrap; }
.ticker { display:inline-block; padding-left:100%;
          animation: scroll 12s linear infinite; }
.ticker:hover { animation-play-state: paused; } /* accessibility */
@keyframes scroll { from { transform:translateX(0); }
                    to   { transform:translateX(-100%); } }
</style>

<div class="view"><span class="ticker">Your long message goes here...</span></div>

Tips:

  • Prefer ellipsis (AutoEllipsis=true) if constant movement could hurt UX.
  • Expose a way to pause (hover or a Pause button) for accessibility.
  • For dynamic text widths, measure with TextRenderer.MeasureText(...) if you need smarter reset logic.

Scroll text ok, but what did you mean by "if the text do not fit into the label..." ?
ADDED: Text always fits to the label.

A Label is just that: a Label.
Add some scrollbars to your Form, or put your text in a TextBox and add some scrollbars there.

I did the code for scrolling text in label.
Take a look at it:

public Form1()
        {
            InitializeComponent();
            label1.Text = "abcde";
        }

        private void button1_Click(object sender, EventArgs e)
        {
            char[] chars = label1.Text.ToCharArray();
            char[] newChar = new char[chars.Length];

            int k = 0;
            for (int j = 0; j < chars.Length; j++)
            {
                if (j + 1 < chars.Length)
                    newChar[j + 1] = chars[j];
                else
                {
                    newChar[k] = chars[j];
                    k++;
                }
            }
            label1.Text = new string(newChar);
        }

public Form1()
        {
            InitializeComponent();
            label1.Text = "abcdefg";
        }

       

        private void button1_Click(object sender, EventArgs e)
        {
            char[] chars = label1.Text.ToCharArray();
            //MessageBox.Show(chars[1].ToString());
            char[] newChar = new char[chars.Length];
            int l = chars.Length;
            int k = 0;
            for (int j = 0; j < chars.Length; j++)
            {
                
                if (j+1  < chars.Length)
                    newChar[j ] = chars[j+1];
                else
                {
                    newChar[l-1] = chars[k];
                  //  k++;
                }
            }
            label1.Text = new string(newChar);
        }

thanks a lottt again.... :) mainly MITJA..
