Datasource in tree

[David]

Hello there. 
I am using kendo Mvc Ui on my application. 
In my scenario I have to used a tree view on the left side, and on the right the details section. when i click a node from the tree view, on details section it will show its details.

It is fine upto now, now the problem is like I need to show records from two tables on the tree.
Like, I have a sector table, Id and Name, another table category is Id, SectorId and name.
So now I have to bind the grid as

Sector1
      Category1
      Category2
             Category2-1
              category2-2

Sector2
      Category1
      Category2
             Category2-1
              category2-2

and it is based on ajax data source.

here is my configurations

@(Html.Kendo().TreeView()
   .Name("categoryList")
   .DataTextField("Name")
   .DragAndDrop(true)
   .DataSource(ds =>
   {
       // ds.Read("ajaxCateegoryList", "category");
       ds.Read(read => read.Action("ajaxCateegoryList", "category"));
   })
   .Events(evt =>
               {
                   evt.Expand("expandHandler");
                   evt.Select("selectedHandler");
               })
   )

My controller

public JsonResult ajaxCateegoryList(string id)
       {
           if (string.IsNullOrEmpty(id))
               id = Request.QueryString["id"];

           var cats = new List<Category>();

           if (!string.IsNullOrEmpty(id))
               cats = _categoryService.GetAllCategoriesByParentCategoryId(Convert.ToInt64(id)).ToList();
           else
               cats = _categoryService.getAllParentCategories();


           var model = cats.Select(x =>
               {
                   return new
                   {
                       id = x.Id,
                       Name = x.Name,
                       hasChildren = _categoryService.GetAllCategoriesByParentCategoryId(x.Id).Count > 0
                   };
               });

           return Json(model, JsonRequestBehavior.AllowGet);
       }

This one is being used for only category navigation. I m clue less how to make it sector base from ajax datasource, I means how the tree will understand what is sector and what is category.

Hi David,

Currently this functionality is not supported out of the box, however similar behavior could be achieved either by binding the TreeView to local data or by using Hierarchical DataSource for Kendo UI Web.
