Hi,
  I'm not able to start_edit() a new node at the 2nd Level client-side if the parent node does not have any child previously and this is the only child.

Below is the code I've written to add a new node.

   function AddNode(parentNode)
   {
   var tree = parentNode.get_treeView();
   tree.trackChanges();
   var node = new Telerik.Web.UI.RadTreeNode();
   node.set_text("New Node");
   node.set_value("New Node");
   parentNode.get_nodes().add(node);
   node.select();
   tree.add_nodeEdited(NodeAdded);
   tree.commitChanges();
   node.startEdit();
   }

at the node.startEdit() statement it throws an error as: "htmlfile: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus."

Please note that the ExpandMode of the Nodes are "WebService"

Hi Himanshu,

This kind of error usually occurs in IE when you try to focus an element which is not visible.

In order to overcome this issue try to expand the parent item before you call the startEdit method.

Please try the following implementation of the AddNode function:

function AddNode(parentNode) {

var tree = parentNode.get_treeView();

tree.trackChanges();

var node = new Telerik.Web.UI.RadTreeNode();

node.set_text("New Node");

node.set_value("New Node");

parentNode.get_nodes().add(node);

parentNode.expand();

node.select();

tree.add_nodeEdited(NodeAdded);

tree.commitChanges();

setTimeout(function() { node.startEdit() }, 20);

}
