Get model of the selected item

[bashis]

Good day. This must be a very basic thing to do, though I didn't manage to find any information on it.

 

I have a treeview setup like this:

@(
  Html.Kendo().TreeView()
      .Name("treeview")
      .DataTextField("Text")
      .DataSource(dataSource => dataSource.Read(read => read.Action("GetView", "Tree"))
   )

My controller looks like this:

    public class TreeController : Controller
    {
        private readonly IRepository _repository;

        public TreeController(IRepository repository)
        {
            _repository = repository;
        }

        [HttpGet]
        public JsonResult GetView()
        {
            var items = _repository.GetItems();
            var viewmodel = items.Select(t => new
            {
                id = t.Id,
                Text = t.Text,
                hasChildren = t.HasChildren
            });
            return Json(viewmodel, JsonRequestBehavior.AllowGet);
        }

}

That part works just fine.

Now, I would like to add a button that would, say, rename the selected item. So,I know how to get the selected item in the treeview. What I do not know how to implement is the connection viewmodel -> data model. That is, knowing the selected html item I have no idea how to get the model item it coresponds to. That would be solvable if I could add my custom html "model-id" property on every item and pass it back to controller on my button click. Which I have no idea how to implement either.

 

Thank you in advance.

Hello,

 

Note that updating the model and persisting a component's settings concerns MVC and not the Treeview widget. The developer needs to implement the logic for his project. However, as an exception, I have  attached a sample MVC project that shows a rename button for each Treeview node and updates the model with a new value provided by the user. Generally, I've covered almost the same scenario, but you'll need to style it and adjust the logic to your project.
