The search as you type functionality is not available for the RadTreeListView
control. Thus, the search panel was removed from the control template of the control, however, as the release notes state, this was not true for the Green
themes until the R1 2017 release. As of 2017.1.117
, the panel is not present in all of our themes and can thus not be used.
I hope this answers your question.
