Hi anilkoomar_1202,

Thank you for posting in the community.

Removing individual nodes client-side can be achieved using the remove() function. For instance the first child of the first root can be done using:

ig_controls.WebDataTree1.getNode(0).get_childNode(0).remove()

You can "clear" all items from the tree by removind all root nodes. This can be achieved using something similar to:

        function removeAll() {
            while (ig_controls.WebDataTree1.getNodes().get_length() > 0) {
                ig_controls.WebDataTree1.getNodes().getNode(0).remove();
            }
        }

Please let me know if this helps.
