  I need to handles the selectedIndexChanged event, but only in response to a user selecting an entry from the dropdown, not in response to making changes to itemsSource.

  How can I reliably tell in my event handler that the change was prompted in response to user interaction and not automatically?

  I’ve tried examining the isDroppedDown property in the selectedIndexChanged event handler, but this always set to false.

  Do I need to set a flag on the drop down event and track it in some way?

  Hello,

  Yes, you can check whether the event is raised by user selection or not by setting the flag in the isDroppedDownChanged event. Please refer to the sample link below for the same:

  Thanks sonu, I used a very similar method in the end, all working as expected
