Hi Jaya, You can use a timer for this. On tick event of timer set line shape visibility to true and false and you can stat the timer on the button click like this:\

```
namespace WindowsFormsApplication3{    public partial class Form1 : Form    {        Timer timer = new Timer();        public Form1()        {            InitializeComponent();        }        private void button1_Click(object sender, EventArgs e)        {            timer.Start();        }        private void Form1_Load(object sender, EventArgs e)        {                       timer.Interval = 1000;            timer.Enabled = true;            timer.Tick += new System.EventHandler(timer_Tick);        }        private void timer_Tick(object sender, EventArgs e)        {            if (lineShape.Visible)            {                lineShape.Visible = false;            }            else            {                lineShape.Visible = true;            }        }    }}
```
