title: ComboBox: Adding Text and Value to an Item (no Binding Source)
body: <p>In C# WinApp, how can I add both Text and Value to the items of my ComboBox?
  I did a search and usually the answers are using "Binding to a source".. but in my case I do not have a binding source ready in my program...
  How can I do something like this:</p>
  
  <pre><code>combo1.Item[1] = "DisplayText";
  combo1.Item[1].Value = "useful Value"
  </code></pre>
