[Solved] Help with Grid tutorial

[Elaine Sum]

Hi there,

I am new to ASP.NET MVC and Telerik and just starting out with these technology. I am following the introduction documentation that came with the Telerik Extensions for ASP.NET MVC with trying to build a Grid in my application.

After creating the controller to reference my model, I am now stuck at binding the model to my view page.

This is the code from my index.aspx:

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Telerik1.Models.Order>" %>

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

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

<%= Html.Telerik().Grid(Model)
        .Name("OrdersGrid")
        .Columns(colums =>
        {
            colums.Bound(o => o.OrderID);
            colums.Bound(o => o.ShipAddress);
            colums.Bound(o => o.RequiredDate);
        })
        .Pageable()
        .Sortable()
%>
</asp:Content>

Somehow Visual Studio 2010 is telling me that <%= Html.Telerik().Grid(Model) is an error. 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.

Can someone please tell me where I am going wrong?

Just to bump this thread again. I tried running the Grid examples that came with Telerik MVC Extensions and they all reported the same error. The live demo from the Telerik website worked fine but not the examples that came with Telerik. Is this due to the MVC extensions not being supported on Visual Studio 2010? or .Net 4?

Hello Elaine Sum,

Telerik Extensions for ASP.NET MVC are supported on Visual Studio 2010. For you reference I am attaching the sample project converted to VS2010 format.

I tried building and running the examples that you gave me but came up with this error: "No overload for method ToGridModel". The offending line is this:
                         return northwind.Orders.ToGridModel(page, size, orderBy, filter);

I found the answer to my problem on one of your developer's blog post. The problem was with the viewpage declaration on Telerik's documentation and I had to install ASP.NET MVC 2 RC as well.

I had to do use Inherits="System.Web.Mvc.ViewPage<IEnumerable<TelerikMVC2.Models.Order>>" instead of what was specified in the documentation.

Would there be an update to the documentation released in future?
