The property is obsolete and EdgeSensitivityOnTop resp.
EdgeSensitivityAtBottom should be used instead. The sample TreeViewAdvDragDrop does still use the obsolete property, too.
Could you give me an idea on how to use the new properties instead?

You could replace the EdgeSensitivity property with the EdgeSensitivityAtBottom and EdgeSensitivityOnTop properties as shown in the code below.
//this.treeViewDragHighlightTracker.EdgeSensitivity = e.HighlightNode.Bounds.Height / 2;
this.treeViewDragHighlightTracker.EdgeSensitivityAtBottom = -1;
this.treeViewDragHighlightTracker.EdgeSensitivityOnTop = -1;
It basically allows you to specify the height on bottom/top portion of the node that responds to drag-drop of nodes. Setting it to 0 will disallow the drag-drop of nodes on that particular edge (top/bottom). Please refer to the class reference for more information. I have modified the TreeViewAdvDragDrop sample and have attached it here. Please refer to it and let me know if you need further assistance. thanks for your interest in Syncfusion products.
