Thank you for your interest in the TreeListView! Please note that the control is a CTP, so it may change in future versions.
This should put the currently selected item in edit mode:
To get the editing working, you need to set the IsEditable
property on the TreeList and the same property on the column you want to be editable. In this version you need to specify a CellEditTemplate
for the column explicitly.
Hopefully this will work for you,
the Telerik team
