The Timer control allows you to set a time interval to peridically execute an event at a specified interval. It is useful when you want to execute certain applications after a certain interval. Say you want to create a hourly backup of your data. You can make a routine that will take the backup and call that routine in the Timer's event and set the timer interval for an hour.

Using timer control is very simple. To demonstrate this I am going to make an application in which 5 seconds after button click a message box will be displayed “Timer working”.

To use timer control drag and drop timer control from tool box to the form.

Coding 

Code at button click event.

private void btnClick_Click(object sender, EventArgs e)
        {
//setting interval of timer to 5000 miliseconds.
//1000 miliseconds = 1 sec
//so 5000miliseconds = 5 sec.
            timer1.Interval = 5000;
//starting timer.
            timer1.Enabled = true;
        }
 
//code for timer tick event
        private void timer1_Tick(object sender, EventArgs e)
        {
//displaying message box.
            MessageBox.Show("Timer Working");
//stoping timer.
            timer1.Enabled = false;           
        }
