I have found one similar article for this issue (http://www.telerik.com/community/forums/silverlight/gridview/hide-grouped-column.aspx
). However this is for the old telerik version.
RadGridView now generates the new ColumnGroupDescriptor by default,
which lacks the Member and AggregateFunctions properties of
GroupDescriptor and instead relies on its Column. It means
c.UniqueName == e.GroupDescriptor.Member
won't work now.
So, would like to tell me how can I achieve hiding grouped column function?
Thank you very much!
