    [CLOSED] Ambiguous call between ComboBoxBase.Builder methods (string) and (params string[]) in a PartialView

    I don't know if I am just being block headed or if I have another version of a bug similar to this:
    http://forums.ext.net/showthread.php...(Razor-syntax)

    When I run the same code in a view that is not a partialview I get no errors, but when it is partial I get the following error:

    The call is ambiguous between the following methods or properties: 'Ext.Net.ComboBoxBase.Builder<Ext.Net.ComboBox,Ext .Net.ComboBox.Builder>.Items(string)' and 'Ext.Net.ComboBoxBase.Builder<Ext.Net.ComboBox,Ext .Net.ComboBox.Builder>.Items(params string[])'


    This is my code
    Controler:
            public ActionResult CreatePartial()
        {
            ViewBag.AdvisorListItems = (from advisor in db.Advisors select advisor).AsEnumerable().Select(x => new ListItem(x.AdvisorName, x.AdvisorId));
            return new Ext.Net.MVC.PartialViewResult { ViewName = "_CreateClient" };
        }
    PartialView:
    @model MvcApplication6.Models.Client    
@(Html.X().Window()
        .Width(370)
        .Height(400)
        .Title("Create Client")
        .Items(
            Html.X().FormPanel()
            .Layout(LayoutType.Form)
            .BodyPadding(10)
            .Frame(true)
            .Items(
                Html.X().TextFieldFor(m => m.Name),
                Html.X().DateFieldFor(m => m.IAASigned),
                Html.X().TextFieldFor(m => m.ClientCategory),
                Html.X().CheckboxFor(m => m.IsActive),
                Html.X().TextFieldFor(m => m.State),
                Html.X().ComboBoxFor(m => m.AdvisorId).Items(ViewBag.AdvisorListItems),
                Html.X().Button().Text("Submit").DirectEvents(de => de.Click.Url = Url.Action("Create"))
            )
        )
    )

    Hi @JakeM,

    Please try the following.
    @Html.X().ComboBoxFor(m => m.AdvisorId).Items(ViewBag.AdvisorListItems as IEnumerable<ListItem>)

    Thanks for the response @Daniil. I made the change you suggested and it is now throwing an "ArgumentNullException was unhandled by user code". Any further help would be greatly appreciated.

    The following works.

    View
    <!DOCTYPE html>
<html>
<head>
    <title>Ext.Net.MVC v2 Example</title>    
</head>
<body>
    @Html.X().ResourceManager()
 
   @Html.X().ComboBox().Items(ViewBag.ListItems)
</body>
</html>
    Controller
    public ActionResult Index()
{
    this.ViewBag.ListItems = new List<ListItem>()
    {
        new ListItem("Item 1", "1"),
        new ListItem("Item 2", "2")
    };
    return View();
}
    So, please try to cast to List<ListItem> in the controller.

    Ok, I have made the following changes and I am still getting the same error. Again, if I run the same code, but use a full view instead of partial view it works... only in partialview am I having any problems.

    Controller:
    public ActionResult CreatePartial()
        {
            List<ListItem> AdvisorListList = new List<ListItem>();
            foreach (Advisor advisor in db.Advisors)
            {
                AdvisorListList.Add(new ListItem(advisor.AdvisorName));
            }
            ViewBag.AdvisorListList = AdvisorListList;
            
            return new Ext.Net.MVC.PartialViewResult { ViewName = "_CreateClient" };
        }
    View:
    @model MvcApplication6.Models.Client    

@(Html.X().Window()
        .Width(390)
        .Height(400)
        .Title("Create Client")
        .Items(
            Html.X().FormPanel()
            .Layout(LayoutType.Form)
            .FieldDefaults(d => {
            d.LabelWidth = 80;
            d.InputWidth = 200;
            })
            .Frame(true)
            .Items(
                Html.X().TextFieldFor(m => m.Name),
                Html.X().DateFieldFor(m => m.IAASigned),
                Html.X().TextFieldFor(m => m.ClientCategory),
                Html.X().CheckboxFor(m => m.IsActive),
                Html.X().TextFieldFor(m => m.State),
                Html.X().ComboBoxFor(m => m.AdvisorId).Items(ViewBag.AdvisorListList),
                Html.X().Button().Text("Submit").DirectEvents(de => de.Click.Url = Url.Action("Create"))
                
            )
        )
    )
    Any help would be greatly appreciated.

    Please clarify how do you render a partial view?

    Could you provide a full, runnable test case, please?

    Just to summarize the issue. The combobox is giving an error, but only in the partial view. When I use a button or an action link to get to a full view with the combobox in it, no error is thrown.

    Getting you an accurate test case for what I am doing would require a sql database. I will try giving a very simple version. I am using MVC3 with database first and Razor.

    Assume a database with one table "Advisor" with two columns

    int"AdvisorId"
    string"AdvisorName"
    populated with
    (AdvisorId: 1 AdvisorName: "Joe")
    (AdvisorId: 2 AdvisorName: "Jane")
    (AdvisorId: 3 AdvisorName: "Bob")

    A second table "Client"
    string"Name"
    string"ClientCategory"
    Date"IAASigned"
    bool"IsActive"
    string"State"
    foreign key: int"AdvisorId"
    No population is necessary for the test case, as I am making a "create" view.

    View with button for rendering a partial window:
    @model MvcApplication6.Models.Client
@{
    ViewBag.Title = "Details";
    Layout = "~/Views/Shared/_BaseLayout.cshtml";
    var X = Html.X();
}
@section script
{
}
@(X.ResourceManager())
@section mainStuff
{
@(X.Viewport()
        .Layout(LayoutType.Border)
        .Items(
            X.Panel()
                .ID("North")
                .Region(Region.North)
                .Title("Client Details")
                .Frame(true)
                .Height(200)
                .AutoScroll(true)
                .Collapsible(true),
            X.Panel()
                .Region(Region.Center)
                .BodyPadding(5)
                .AutoScroll(true)
                    .Items(X.Button()
                        .Text("Partial View")
                        .DirectEvents(b => {
                            b.Click.Url = Url.Action("CreatePartial", "Client");
                                            })
                          )
                 .Content(@Html.ActionLink("Create New Client", "Create", "Client", null, null))
)
    Controller:
    public ActionResult CreatePartial()
        {
            List<ListItem> AdvisorListList = new List<ListItem>();
            foreach (Advisor advisor in db.Advisors)
            {
                AdvisorListList.Add(new ListItem(advisor.AdvisorName, advisor.AdvisorId));
            }
            ViewBag.AdvisorListList = AdvisorListList;
             
            return new Ext.Net.MVC.PartialViewResult { ViewName = "_CreateClient" };
        }

        public ActionResult Create()
        {
            ViewBag.AdvisorListItems = (from advisor in db.Advisors select advisor).AsEnumerable().Select(x => new ListItem(x.AdvisorName, x.AdvisorId));
            return View();
        }
        [HttpPost]
        public ActionResult Create(Client client)
        {
            if (ModelState.IsValid)
            {
                db.Clients.Add(client);
                db.SaveChanges();
                return RedirectToAction("Index");
            }

            return View(client);
        }
    The Partial View (in the shared folder)
    @model MvcApplication6.Models.Client    
 
@(Html.X().Window()
        .Width(390)
        .Height(400)
        .Title("Create Client")
        .Items(
            Html.X().FormPanel()
            .Layout(LayoutType.Form)
            .FieldDefaults(d => {
            d.LabelWidth = 80;
            d.InputWidth = 200;
            })
            .Frame(true)
            .Items(
                Html.X().TextFieldFor(m => m.Name),
                Html.X().DateFieldFor(m => m.IAASigned),
                Html.X().TextFieldFor(m => m.ClientCategory),
                Html.X().CheckboxFor(m => m.IsActive),
                Html.X().TextFieldFor(m => m.State),
                Html.X().ComboBoxFor(m => m.AdvisorId).Items(ViewBag.AdvisorListList),
                Html.X().Button().Text("Submit").DirectEvents(de => de.Click.Url = Url.Action("Create"))
                 
            )
        )
    )
    The non Partial View in the Client Folder
    @model MvcApplication6.Models.Client
@(Html.X().ResourceManager())
@{
    ViewBag.Title = "Create";
    Layout = "~/Views/Shared/_BaseLayout.cshtml";
}

@section mainStuff
{
    <h1>Create Client</h1>

    @(
        Html.X().FormPanel()
        .Layout(LayoutType.Form)
        .Width(350)
        .FieldDefaults(d => {
            d.LabelWidth = 150;
        })
        .BodyPadding(10)
        .Frame(true)
        .Items(
            Html.X().TextFieldFor(m => m.Name),
            Html.X().DateFieldFor(m => m.IAASigned),
            Html.X().TextFieldFor(m => m.ClientCategory),
            Html.X().CheckboxFor(m => m.IsActive),
            Html.X().TextFieldFor(m => m.State),
            Html.X().ComboBoxFor(m => m.AdvisorId).Items(ViewBag.AdvisorListItems),
            Html.X().Button().Text("Submit").DirectEvents(de => de.Click.Url = Url.Action("Create"))

        )
    )

    Thank you, I reproduced the issue.

    Here I am posting a simplified example. Such kind of examples we are, ideally, expecting from forum members:) Please take it into account.

    Main View
    @{
    var X = Html.X(); 
}

<!DOCTYPE html>
<html>
<head>
    <title>Ext.Net.MVC v2 Example</title>  
</head>
<body>
    @X.ResourceManager()

    @X.Button().Text("Partial View").DirectClickAction("CreatePartial")
</body>
</html>
    Partial View
    @Html.X().ComboBox().Items(ViewBag.ComboBoxItems)
    Controller Actions
    public ActionResult Index()
{
    return View();
}

public ActionResult CreatePartial()
{
    List<ListItem> items = new List<ListItem>();
    items.Add(new ListItem("Item 1", "1"));
    ViewBag.ComboBoxItems = items;

    return new Ext.Net.MVC.PartialViewResult { ViewName = "_CreateClient" };
}
    We are investigating.

    A ViewBag should be set up for a PartialViewResult.
    public ActionResult CreatePartial()
{
    Ext.Net.MVC.PartialViewResult r = new Ext.Net.MVC.PartialViewResult() { ViewName = "_CreateClient" };

    List<ListItem> items = new List<ListItem>();
    items.Add(new ListItem("Item 1", "1"));
    r.ViewBag.ComboBoxItems = items;

    return r;
}
