TreeView MVC LoadOnDemand ... AllowEdit, DragAndDrop issue

[Lennox McKenzie]

Good afternoon all,

I'm running a test ASP.NET MVC 4 web project and working with the TreeView control (Essential Studio v11.1.0.21).  I have the control wired up for LoadOnDemand, and the nodes all show up and collapse/expand just great.  I want all nodes to not be editable and allow drag-and-drop.  The the top level nodes behave as expected (not editable, are drag-and-drop capable), but the child nodes don't (remain editable, are not draggable/droppable).  I've looked at the sample source provided in the Studio and found that the LoadOnDemand example exhibits this same behavior.  Is there a property that I'm neglecting to set on the TreeView helper in the view to get the AllowEdit(false) and DragandDrop(true) to propagate to the child nodes?

Hi Gurunathan,

I can confirm that the latest version of the tools does correct the drag-and-drop problem.  However, the editing issue still remains.  AllowEdit is set to false, but it's still possible to edit the child nodes.  I see the same behavior in the online example as well.  Is there a fix for this?  Also, there is a significant delay in loading the page with the TreeView.  I've compared the same load on demand functionality using the KendoUI Web TreeView with the same datasource, and the difference is stark (Syncfusion ~26s versus Kendo 900ms).  The only difference between the pages is the tree view control.  Is there a property or configuration option that I can set to improve the performance of the Syncfusion control?
