Hello Tim,
Currently the CTP version of the TreeListView has only very basic support for sorting.
The Q2 version of the control will be based on the GridView and it will inherit all its data features. It is best not to base production code on the control because of the expected changes.
For sorting to work you need to specify the PropertyName="MyProperty" on the column which will identify the property which will be used for sorting.
Best wishes,
Miroslav
the Telerik team
