MVCContrib Grid and nun-nullable parameter

Question

I'm using the MVCContrib Grid. My controller action accepts 3 parameters, the sortoptions and paging parameter for the grid, and a ResourceID parameter, that specifies which resource you want to view bids for.

When i click on the links i get the following error

The parameters dictionary contains a null entry for parameter 'ResourceId' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult ByResource(Int32, MvcContrib.UI.Grid.GridSortOptions, System.Nullable`1[System.Int32])' in 'TaskingApp.Controllers.BidController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.

How do i pass in the ResourceId Parameter in properly?

Here is my Controller action

//Get bids by resource
    public ActionResult ByResource(int ResourceId,GridSortOptions sort, int? page)
    {
        var bids = bidRepo.GetUpcomingBidsByResource(ResourceId);

        if (sort.Column != null)
            bids = bids.OrderBy(sort.Column, sort.Direction);
        ViewData["sort"] = sort;
        return View("Index", bids.AsPagination(page ?? 1, 15));

    }

And here's the actionlink

<%= Html.ActionLink(item.ResourceName, "ByResource", new { id = item.ResourceID })%>

Answer 1

The specified property must match the controllers property name:

new { ResourceId = item.ResourceID }

That, or change your method signature to the following:

ByResource(int id, GridSortOptions sort, int? page)
