title: How to trigger radio button's event handler programmatically?
body: <p>please have a look at the following code</p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using System.ComponentModel;
  using System.Data;
  using System.Drawing;
  using System.Text;
  using System.Windows.Forms;
  
  namespace calc
  {
      public partial class Form1 : Form
      {
          //code removed
  
          public Form1()
          {
  
              InitializeComponent();
              calculator = new Calculator();
  
              maleRadio.PerformClick();
              englishRadio.PerformClick();
          }
  
  
  /*code removed*/
  
          //Action Listener for Female Radio button
          private void femaleRadio_CheckedChanged(object sender, EventArgs e)
          {
              //code removed
          }
  
          //Action Listener for English Radio button
          private void englishRadio_CheckedChanged(object sender, EventArgs e)
          {
              //code removed
          }
  
  
  
      }
  }
  </code></pre>
  
  <p>I am somewhat new to c#. what I want to do here is to trigger the <code>event handlers</code> of radio buttons inside the constructor programatically. The way I followed <code>maleRadio.PerformClick();</code>do nothing. how can I call the event handlers inside the constructor programmertically ?</p>
