I have this code:

    
            <%= Html.Telerik().TreeView() 
        
                    .Name("WorkitemTree") 
        
                    .BindTo(Model, (item,workitem) => 
        
                    { 
        
                        // bind initial data - can be omitted if there is none 
        
                        item.Text = workitem.Title; 
        
                        item.Value = workitem.RowKey; 
        
                        item.LoadOnDemand = true; 
        
                    }) 
        
                    .DataBinding(dataBinding => dataBinding 
        
                            .Ajax().Enabled(true).Select("AjaxTreeSelect", "Workitem")) 
        
            %>

However the Tree is not operational. It is displayed, yes.

But when I expand, nothing happens. Even no controller action is called.
When I hover over the node, nothing happens. Typically the node should change visible state. No. Nothing.

I am not able to reproduce the problem in a clean new project. There it works. So there seems to be any side effect between my productive project and the tree view.

Any idea by anybody what I could do to find the problem?

jquery-validate-min-js.zip

Hello Frank Michael Kraft,

You need to update jquery.validate.js file in order to avoid this issue. The older version has method delegate, which overrides the jquery's delegate method. For your convenience I have attached the correct version of the jquery.validate.js to this message.
