[Solved] Ajax Binding Not Forwarding Values to Control

[Nathan]

Hello,

I am attempting to pass through a value to my bind action using the following code.

<%= Html.Telerik().Grid()
        .Name("Grid")
        .DataBinding(dataBinding => dataBinding.Ajax().Select("Select", "Grid"))
        .ClientEvents(clientEvents => clientEvents.OnDataBinding("dataBinding"))
%>

Here is my dataBinding function.

function dataBinding(args)
{
    var filter = "";
    var filterableColumns = $("[prism-name^=filter-column]");
    for(var i = 0; i < filterableColumns.length; i++)
    {
        if(filterableColumns[i].value != "")
        {
            if(filter != "") { filter += "~"; }
            filter += filterableColumns[i].getAttribute('prism-name').replace("filter-column-", "") + "=" + filterableColumns[i].value;
        }
    }
    args.data = $.extend(args.data, { filter: filter } );
}

And here is my controller.

[GridAction]
public ActionResult _Filter(string filter)
{
    if (filter == null)
    {
        filter = string.Empty;
    }

    var project = filter.DeserializeFilterString<Project>();
    return View(new GridModel<Project>(db.Projects.Where(p => (string.IsNullOrEmpty(project.ProjectType) || p.ProjectType.StartsWith(project.ProjectType))).ToList()));
}

However, when _Filter executes on the binding, the "filter" parameter is null.  Any clues?  I've tried just about everything I can think of.

Thanks!

Nathan
