How can i use the dropdownlist Virtualization with a guid id?

Hi Chris,

 

Thank you for writing to us.

The key to the Virtualization implementation is the ValueMapper function, both on client and server-side:
https://demos.telerik.com/aspnet-mvc/dropdownlist/virtualization

Frankly put, we haven't tested this scenario using GUID values, but you can try to change the logic to use GUID instead of integers and theoretically it should work the same way:

public ActionResult Orders_ValueMapper(int[] values)

Hi Chris,

Actually, I implemented the same with Guid, it's a piece of cake, you should only change the ValueMapper on your controller as follows:

public ActionResult ValueMapper(List<Guid?> values)
        {
            var indices = new List<int>();

            if (values != null && values.Any())
            {
                var index = 0;
                var list = GetJobs();
                foreach (var item in list)
                {
                    if (values.Contains(item.ID))
                    {
                        indices.Add(index);
                    }

                    index++;
                }
            }

            return Json(indices, JsonRequestBehavior.AllowGet);
        }
