I am using RadGridView 2013.1.220.1050, and I am using aggregates. I am trying to follow the sample http://demos.telerik.com/silverlight/#GridView/Aggregates, where I want only "Show group header column aggregates". However, I get the aggregates in-line, but dont get the group header aggregate. Below is how I have my XAML, and I have tried so many things to hide the in-line and only show the group header, but with no success.
