[Solved] The Type or Namespace 'Category' could not be found...

[Peter]

I have been trying to implement the databound example of the Telerik menu control for the past 3 days with relatively no success. I have been able to get just the first level of the menu working, but when I try to link children, I get the error message, "The Type or Namespace 'Category' could not be found..."
The only way I have been able to get the first level to work, however, was to fully qualify my namespace when defining the IEnumerable<T> command and the first mappings.For<T> command.
In the code that I got from the Telerik menu example, there is no need to fully quaify classes inside the IEnumerable<T> command or the mappings.For<T> commands, yet if I do not I get compiler errors.

 

 

 

 

 

@model IEnumerable<SAP_Template.Models.Category>

 

@(Html.Telerik().Menu()

 

.Name("Menu")

 

.BindTo(Model, mappings =>

 

{

 

    mappings.For<Category>(binding => binding

 

        .ItemDataBound((item, category) =>

 

        {

 

            item.Text = category.CategoryName;

 

        })

 

        .Children(category => category.Products));

 

            mappings.For<Product>(binding => binding

 

                .ItemDataBound((item, product) =>

 

            {

 

                item.Text = product.ProductName;

 

            })

 

        );

 

    })

 

)

 

I am coming to you folks as a last resort in the hope that someone may have come across this same problem in the past.  I am not looking to do anything fancy right now.  All I want to do is make a working example that has a bound menu to the Northwind database. Basically, I just want to extract the Telerik databound menu into a separate, MVC 3 C# (Razor) project.  I am sure the problem has something to do with my namespaces, but I have been spinning my wheels for the past 2 days, getting no where...

I have attached a zip file of my C# project. Any help would be greatly appreciated...

Atanas,
Thank you so much for the quick response.  Adding the assembly reference to my web.config file solved the problem!

 

 

 

 

<add assembly="System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

For some reason, when you create a new Telrik, MVC 3 application, this reference does NOT get automatically included for you.

Thanks again...
