Introduction
I think everyone is aware of the marquee tag in HTML that scrolls text and we all also use the marquee tag in .Net applications to scroll text but in a web application. In this article I implement this for a Windows Forms since there is not a control available to scroll the text. So in this article I will scroll the text using the timer control.
Use the following procedure to create this.
First of take the control from the toolbox to design the window. In this article I have taken two buttons, one label and one timer control to implement the marquee in C#.

Now enter C# code for the Left to Right button click event, as in:
private void button1_Click(object sender, EventArgs e)
{
xpos = label1.Location.X;
ypos = label1.Location.Y;
mode = "Left-to-Right";
timer1.Start();
}
And enter it for the left button click, as in:
private void button2_Click(object sender, EventArgs e)
{
xpos = label1.Location.X;
ypos = label1.Location.Y;
mode = "Right-to-Left";
timer1.Start();
}
Here is the full source code in C#:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace marquee_text
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private int xpos = 0, ypos = 0;
public string mode = "Left-to-Right";
private void button1_Click(object sender, EventArgs e)
{
xpos = label1.Location.X;
ypos = label1.Location.Y;
mode = "Left-to-Right";
timer1.Start();
}
private void button2_Click(object sender, EventArgs e)
{
xpos = label1.Location.X;
ypos = label1.Location.Y;
mode = "Right-to-Left";
timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
if (mode == "Left-to-Right")
{
if (this.Width == xpos)
{
this.label1.Location = new System.Drawing.Point(0, ypos);
xpos = 0;
}
else
{
this.label1.Location = new System.Drawing.Point(xpos, ypos);
xpos += 2;
}
}
else if (mode == "Right-to-Left")
{
if (xpos == 0)
{
this.label1.Location = new System.Drawing.Point(this.Width, ypos);
xpos = this.Width;
}
else
{
this.label1.Location = new System.Drawing.Point(xpos, ypos);
xpos -= 2;
}
}
}
}
}
Note : Now run your application and click on the button to see the effect.

Here I have clicked on the Right to Left button.
