title: How to copy all items from a ComboBox to another ComboBox?
body: <p>I want to make a Button that -in click- must copy all items in  <code>ComboBox1</code> and put them into <code>ComboBox2</code> located in another <code>Form</code>. I am sure that it is doable with looping through the <code>ComboBox</code> Items but, I have no idea how to do it .
  Any help will be appreciated.</p>
  
  <p>Thanks and Regards</p>
