Question

I created an NinjectResolver which implements IDependencyResolver. In the global.asax, I’m setting this guy as my DependencyResolver.

However, in doing so, I lose all of my data-dash attributes on validaiton. And it also messes up the entire client-side paging, sorting on my grid (using Telerik’s MVC extensions).

Here’s the class:

public class NinjectResolver : IDependencyResolver
{
    private readonly IKernel _kernel;

    public IKernel Kernel
    {
        get
        {
            return _kernel;
        }
    }

    public NinjectResolver(params Ninject.Modules.INinjectModule[] modules)
    {
        _kernel = new StandardKernel(modules);
    }

    public object GetService(Type serviceType)
    {
        return _kernel.TryGet(serviceType);
    }

    public IEnumerable<object> GetServices(Type serviceType)
    {
        return _kernel.GetAll(serviceType);
    }

    public IBindingToSyntax<T> Bind<T>()
    {
        return _kernel.Bind<T>();
    }
}

And here’s my app start in global.asax …

    protected void Application_Start()
    {
        .... omitted

        var modules = new Ninject.Modules.INinjectModule[] 
        { 
            new PersistenceModule()
        };

        var dependencyResolver = new NinjectResolver(modules);
        DependencyResolver.SetResolver(dependencyResolver);

        .... omitted
    }

If I comment out the SetResolver line, all my client-side validation works as well as my client-side grid sorting, paging, filtering, etc. Unfortunately, I lose all my constructor injection.

Any help is appreciated please. Not sure if I have to add more modules for client side operations to work?

Please advise.

Why don’t you use https://github.com/ninject/ninject.web.mvc/wiki/MVC3 instead of writing your own implementation? It is widely used and proven to work in many projects.
