The type or namespace name 'MVCGridToolbarModel' could not be found (are you missing a using directive or an assembly reference?)

[michaeltaylor1329]

I have

1. the MVCGrid Reference
2. MVCGridToolbarModel.cls in the Models folder
3. MVCGridConfig.cs in the App_Start folder
4. <script src="~/MVCGridHandler.axd/script.js"></script> in the _Layout.cshtml view
5. _MVCGridToolbar.cshtml in the Shared view folder
6. in the web.config
7. MVCGridConfig.RegisterGrids(); in Application_Start()
8. @Html.Partial("_MVCGridToolbar", new MVCGridToolbarModel()
   {
   MVCGridName = "Orders",
   PageSize = true,
   ColumnVisibility = true,
   Export = true,
   GlobalSearch = true
   })
   @Html.MVCGrid("Orders") In the Index.cshtml view

What am I missing?

thanks!
