Set startEdit on node in ClientNodeEditing

[Jan]

Hi Everybody,

I would like to crete new node on clientside and set this node to edit mode. And when user doesn't change the label and click outside, i would like show radalert and cancel postback -  so far so good. But after that I would like to set node to edit mode again. And I'm getting strange unhanded exceptions from code. This is my snippet:

function onClientNodeEditing(sender, eventArgs) {
                var node = eventArgs.get_node();
                var oldText = node.get_text();
                var newText = eventArgs.get_newText()
                var tree = $find("<%= ThreadRoot.ClientID %>");

                if (newText == oldText) {
                    radalert(Please change name of category!");

                    tree.trackChanges();
                    node.startEdit();
                    tree.commitChanges();


                    eventArgs.set_cancel(true);
                }
            }

Any ideas? for example this code returns Cannot set property 'onblur' of null (G Chrome) and stops execution with Uncaught RangeError, Maximum call stack size exceeded

Hello Jan,

Could you please try it like this:

function nodeEditing(tree, eventArgs) {
     var node = eventArgs.get_node();
        var oldText = node.get_text();
        var newText = eventArgs.get_newText()

        if (newText == oldText) {
            radalert("Please change name of category!");
            eventArgs.set_cancel(true);
            setTimeout(function() { node.startEdit(); }, 100);
        }
 }

and let us know how it goes.
