After binding sorted EntryCollection to GridView in anythere, exception occurred then binding new EntryCollection (sorted or not sorted).
Code, for instance :
_
ContactListViewCollection list = new ContactListViewCollection();
list.SupportsSorting = true;
_gvContactList.DataSource = list;
_gvContactList.DataBind(); <------------ Error
_
And we have System.NotSupportedException: The data source does not support sorting. Exception
???
