Hi,
Based on the code snippets you provided, we couldn't find anything wrong in your code. Therefore, we think that the problem could be related on the way you are subscribing and raising the property changed event on the ShowInd property. It would be helpful if you could provide us a code snippet showing this property logic so that we can analyze it in further detail.
Thanks,
