Whether Node.get_parent Returns the Parent Node or the Parent Treeview

Use the following code to check whether a node or a TreeView instance is returned by the get_parent() method:

JavaScript

	     
	
	// node is root node and get_parent() returns the parent TreeView
	if (node.get_parent() == node.get_treeView())    
				

or test the node level for zero:

JavaScript

//node is a root node  
if (node.get_level() == 0)
