Hi, I want to make a DropDownList with the dataSource from UrlAdaptor. I start using JS2, and I do not know if it is configured the same as JS1
I have my code here:

@(Html.EJS().DropDownList("Album")
        .DataSource(ds=>
        {
            ds.Url("/JS2/Albums").Adaptor("UrlAdaptor");
        })
        .Fields(new Syncfusion.EJ2.DropDowns.DropDownListFieldSettings
        {
            Text="Titulo", Value="AlbumId"
        })
        .Placeholder("Hola")
        .PopupHeight("200px")
        .Render()
        )

public ActionResult Albums()
        {
            var result = read.GetAlbums();
            var count = result.Count;

            return Json(new { result = result, count = count }, JsonRequestBehavior.AllowGet);
        }

I have two other questions
a) When configuring JS2 and adding the namespaces of Syncfusion.EJ2 in web.config (following the instructions in the documentation), when I try to use a control I can because I get a message saying that I am missing a reference and I always have to put at the start of my .cshtml @using Syncfusion.EJ2
Why is this happening?

b)If in my MVC project I have areas, how can I be able to in ds.Url ("/ JS2 / Albums") to add an area? Or is it not necessary to add the area?
Thanks in advance

Hi Juan, 

Thank you for contacting Syncfusion support. 

We already have documentation for datasource with url Adaptor. Please refer the below code snippet and the documentation, 
code snippet
[.cshtml] 
<div id='url-data' class='col-lg-6' style='padding-top:15px'>  
    <div class='content'>  
    @Html.EJS().DropDownList("games").Placeholder("Select a Country").PopupHeight("200px").DataSource(dataManger => dataManger.Url("/DropDownList/UrlDatasource").Adaptor("UrlAdaptor").CrossDomain(true)).Fields(new ComboBoxFieldSettings { Value = "ShipCountry" }).Render()  
    </div>  
</div> 

[.cs] 
public IActionResult UrlDatasource([FromBody]Data dm) 
{ 
    var val = OrdersDetails.GetAllRecords(); 
    var Data = val.ToList(); 
    var count = val.Count(); 
    if (dm.where != null) { 
        Data = (from cust in Data 
        where cust.ShipCountry.ToLower().StartsWith(dm.@where[0].value.ToString()) 
        select cust).ToList(); 
    } 
    if (dm.take != 0) 
        Data = Data.Take(dm.take).ToList(); 
    return Json(Data); 
}
