    Hi everyone,

    I am having hard time getting the model binding work with the DropdownList.

    * I am not manually setting the name on the widget
    * I do not have AutoBind set to false 

    @(Html.Kendo().DropDownListFor(m=> m.SelectedProduct)
              .HtmlAttributes(new { style = "width: 250px" })
              .DataSource(source =>
                  source.Read(read =>
                      read.Action("GetProducts", "DropdownList");

    This is from the telerik demos.

    Here is the Controller Code:
    public ActionResult RemoteDataSource()
               var model = new RemoteDataSourceViewModel()
                   SelectedProduct = new SelectedProduct()
                       ProductID = 7,
                       ProductName = "Uncle Bob's Organic Dried Pears"
               return View(model);

    The above code would load the dropdownlist, but doesn't set the value on initial load.

    I looked through previous post and could not find why this wouldn't work.

    Any suggestions on what I might be doing wrong?

    I appreciate your time.

    Hi Uday,

    This happens because the DropDownList's value should be an integer matching the ProductID. Using the ProductID property (instead of a complex object) as an argument for the DropDownListFor helper should do the trick.
