title: How do you refresh a combo box item in-place?
body: <p>The ComboBox Items collection is an ObjectCollection, so of course you can store anything you want in there, but that means you don't get a Text property like you would with, say, a ListViewItem. The ComboBox displays the items by calling ToString() on each item, or using reflection if the DisplayMember property is set.</p>
  
  <p>My ComboBox is in DropDownList mode. I have a situation where I want to refresh the item text of a single item in the list when it gets selected by the user. The problem is that the ComboBox doesn't re-query for the text at any time besides when it loads up, and I can't figure out how else to do what I want besides removing and re-adding the selected item like so:</p>
  
  <pre><code>
  PlantComboBoxItem selectedItem = cboPlants.SelectedItem as PlantComboBoxItem;
  
  // ...
  
  cboPlants.BeginUpdate();
  
  int selectedIndex = cboPlants.SelectedIndex;
  cboPlants.Items.RemoveAt(selectedIndex);
  cboPlants.Items.Insert(selectedIndex, selectedItem);
  cboPlants.SelectedIndex = selectedIndex;
  
  cboPlants.EndUpdate();
  </code></pre>
  
  <p>This code works fine, except for the fact that my SelectedIndex event ends up getting fired twice (once on the original user event, and then again when I re-set the property in this code). In this case, it's not a big deal that the event is fired twice, but it's inefficient, and I hate that. I could rig up a flag so it exits the event the second time, but that's hacking.</p>
  
  <p>Is there a better way to get this to work?</p>
