  How do I clear a C1ComboBox’s selection to show the placeholder value again? I noticed on initial load, when no selection is made, the SelectedIndex is -1. I tried setting the SelectedIndex back to -1 and I also tried setting the SelectedItem to null. While the SelectedIndex or the SelectedItem may have changed, the C1ComboBox still displayed the previous selected item, rather than the placeholder value.

  Hi Jared

  I think there’s a bug here. I’d expect setting the Text property to an empty string would clear the display, but it seems like it doesn’t have an effect. I’ll talk to the developers about getting a fix.

  A workaround for now seems to be setting the ItemSource to null and then resetting the ItemSource to the original data source.

  MyC1ComboBox.ItemsSource = null;
  MyC1ComboBox.ItemsSource = _myDataSource;

  Thanks, Kelley! I will give this build a test and let you know how it goes.

  Hi Jared

  I have a prerelease build that you can test locally which should solve the initial issue. QA is reviewing it right now, and if they don’t find any problems it should be published to NuGet as well. Just so you’re aware this build also adds XF 2.5 support.

  //238 is now available on NuGet.org
