I have a Grid with foreign key column 'Products' with custom editor template. There is a separate button 'Add new Product; which opens up a modal to add new product . After adding new product when I try to create a new record in the Grid and select the newly added product, it shows up as blank in the Grid. When I refresh the page it shows up then. What I am missing?

Foreign key in grid:

columns.ForeignKey(c => c.ID, (System.Collections.IEnumerable)ViewData["products"], "ID",  "ProductName").Title("Product")..EditorTemplateName("RemoteForeignKeyProducts).

 
'RemoteForeignKeyProducts' is the custom editor template for products:
@model object 
@(Html.Kendo().DropDownListFor(m => m)
  .DataSource(source =>
  {
      source.Read(read =>
      {
         read.Action("GetProducts", "Home").Type(HttpVerbs.Post);
      }).ServerFiltering(false);
  })
  .DataValueField("ID")
  .DataTextField("ProductName")

)

GetProducts() is a function in controller
  public ActionResult GetProducts()
        {
            using (     var db = new Entities())
            {
                var objects = db.Products.Select(p => new { p.ID, p.ProductName}).ToList();

                return Json(objects);
            }

        }

Hello,

Based on the information provided it would be difficult to determine what is causing the problem. Can you please send us the entire grid code alongside with the controller actions and models so we could examine the setup? If you can instead send us a small sample that would be great.

Additionally please check whether the request is executed and exceptions are not thrown.

Regards,
