Triggered before a subgroup gets collapsed.

Event data

treeview.data("kendoTreeView").bind("drag", function(e) {
    if ($(e.dropTarget).parents("#drop-area").length ) {
        e.setStatusClass("k-denied");
    }

dropTarget : DomElement

The element that the node is placed over.

pageX : Integer

The x coordinate of the mouse.

pageY : Integer

The y coordinate of the mouse.

statusClass : String

The status that the drag clue shows.

setStatusClass : Function

Allows a custom drag clue status to be set.

Pre-defined status classes are:

k-insert-top - Indicates that the item will be inserted on top.
k-insert-middle - Indicates that the item will be inserted in the middle.
k-insert-bottom - Indicates that the item will be inserted at the bottom.
k-add - Indicates that the item will be added/appended.
k-denied - Indicates an invalid operation. Using this class will automatically make the drop operation invalid, so there will be no need to call setValid(false) in the drop event.
