title: WPF Listview Columnheader Click Event
body: <p>I have a ListView (GridView) in WPF and I'm trying to implement sorting according to <a href="http://msdn.microsoft.com/en-us/library/ms745786.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/ms745786.aspx</a>. In my case, the celltemplate for one of the columns contains an Expander. Now when I click the expander header, the GridViewColumnHeader.Click event fires. How do I prevent this from happening?</p>
