[Solved] Binding Grid Error

[regis]

Good morning everyone,

I am experiencing problem with binding the grid. I have to precise this is my first time using MVC framework and telerik MVC controls.
I try two different ways according to server binding instruction but still get some errors

Unless I am wrong my views are strongly typed according the inherits value of the page declaration.

here is my first way

controller:

public ActionResult Index()
        {
            CasEntities db = new CasEntities();


            return View(db.NUMBERSet.ToList());
        }

view:

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<AdminCAS.Models.NUMBER>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    Index
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

    <h2>List of CAS Number</h2>

    <%= Html.Telerik().Grid(Model)
        .Name("NumberGrid")
        .Pageable()
        .Sortable()%>

</asp:Content>

Doing this I get the followinf error:

Server Error in '/' Application.
--------------------------------------------------------------------------------

Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS0411: The type arguments for method 'Telerik.Web.Mvc.UI.ViewComponentFactory.Grid<T>(System.Collections.Generic.IEnumerable<T>)' cannot be inferred from the usage. Try specifying the type arguments explicitly.

Source Error:



Line 9:      <h2>List of CAS Number</h2>
Line 10:
Line 11:     <%= Html.Telerik().Grid(Model)
Line 12:         .Name("NumberGrid")
Line 13:         .Pageable()

So I modify my view specifying the model type into grid declaration:

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<AdminCAS.Models.NUMBER>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    Index
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

    <h2>List of CAS Number</h2>

    <%= Html.Telerik().Grid<AdminCAS.Models.NUMBER>(Model)
        .Name("NumberGrid")
        .Pageable()
        .Sortable()%>

</asp:Content>

and get the following error:

Server Error in '/' Application.
--------------------------------------------------------------------------------

Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1502: The best overloaded method match for 'Telerik.Web.Mvc.UI.ViewComponentFactory.Grid<AdminCAS.Models.NUMBER>(System.Collections.Generic.IEnumerable<AdminCAS.Models.NUMBER>)' has some invalid arguments

Source Error:



Line 9:      <h2>List of CAS Number</h2>
Line 10:
Line 11:     <%= Html.Telerik().Grid<AdminCAS.Models.NUMBER>(Model)
Line 12:         .Name("NumberGrid")
Line 13:         .Pageable()

If someone can point me what I may doing wrong, would be great. Thank you!

Hi,
I manage to get it work by modifying my page declaration to :

 

<%

@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<AdminCAS.Models.NUMBER>>" %>

 

I am just surprised (even if it mention into the introduction of the grid webpage) that my model would be a type IEnumerable as my true model is not a list (Not sure how clear is the last sentence).

But the important is that it's working.
