title: Populate a combobox in DropButtonClick
body: <p>I am trying to populate a combobox as it is needed, by doing the population in the DropButtonClick function. As a simple example:</p>
  
  <pre><code>Private Sub cmbAdvisor_DropButtonClick()
      cmbAdvisor.Clear
  
      cmbAdvisor.AddItem ("Test1")
      cmbAdvisor.AddItem ("Test2")
  End Sub
  </code></pre>
  
  <p>This works fine, and the values are shown in the drop down list. However, when I click on one of them, the drop down list goes away, and the combobox now displays nothing/blank. I would expect it to display the item that I had selected. I'm guessing the problem is that I am doing a Clear inside of this function - but how else would I go about this?</p>
