Hello
How can I make a grid with self-reference hierarchy using LinqDataSource?
I followed this demo: http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/selfreferencing/defaultcs.aspx
but the grid could load root level items only.
Is the FilterExpression the reason? This is my FilterExpression, with datakeys CategoryID and ParentID :
Hope the answer will come soon...

RadGrid1.MasterTableView.FilterExpression = @
"ParentID == null"
