title: C# listview itemcheck or itemchecked event
body: <p>I have a listview with first column as checkbox for each item.</p>
  
  <p>I wanted to add an itemcheck or itemchecked event when the user tick a box that trigger fires.</p>
  
  <p>I have added to my code:</p>
  
  <pre><code>private void ListView1_ItemCheck1(object sender, 
  System.Windows.Forms.ItemCheckEventArgs e)
  {
    MessageBox.Show("has been checked");
  }
  </code></pre>
  
  <p>For some reason, the event does not seem to be triggering.</p>
  
  <p>Also, I found out that <code>private void listView1_SelectedIndexChanged</code> works when you click on one of the list items (as if you're selecting)</p>
  
  <p>Have you come across this issue?</p>
