title: inheritance between buttons C# - windows form
body: <p>I have a doubt simple principle in C # windows form. 
  I have two forms: FormA and FormB. 
  The formA has buttonA button with one messagebox => <code>MessageBox.Show ("FormA");</code></p>
  
  <p>The FormB is inherited from FormA whose buttonA changed so I can write another messagebox => <code>Console.WriteLine ("FormB");</code> </p>
  
  <p>Until then all right, but I need the event of FormB button to run before the button FormA the event, ie: First <code>MessageBox.Show ("FormB")</code> then <code>MessageBox.Show ("FormA");</code></p>
  
  <p>How do I do that?</p>
