[Solved] Ajax Binding and Validation Problems after Upgrade

[mark]

I just upgraded from 2011.1.414.340 to 2011.2.712.340 and have run into a couple of issues with my grids that use ajax binding.

I have the following grid:

@(Html.Telerik().Grid<UnitVM>()
    .Name("unit_list")
    .DataKeys(dataKeys => dataKeys.Add("UnitId"))
    .ToolBar(toolBar => toolBar.Insert())
    .Columns(columns => {
        columns.Bound(m => m.UnitId).Width("5em");
        columns.Bound(m => m.Name).Width("20em");
        columns.Bound(m => m.Description);
        columns.Command(command => { command.Edit(); }).Width("8em");
    })
    .Editable(editable => editable.TemplateName("Edit").Mode(GridEditMode.PopUp))
    .DataBinding(dataBinding => dataBinding.Ajax()
        .Select("_Select", "Unit", new { appId = @Model.SelectedAppId })
        .Update("_Update", "Unit", new { appId = @Model.SelectedAppId })
        .Insert("_Insert", "Unit", new { appId = @Model.SelectedAppId }))
    .Pageable()
    .Sortable()
    .Groupable()
    .Filterable()
)

If I return a View from my action, nothing is bound.  For example, if I implement _Select as follows, nothing is bound to the grid:

[GridAction]
public ActionResult _Select(int appId) {
    return View(new GridModel<UnitVM> { Data = GetUnits(appId) });
}

If I change the action to return Json instead of View, it works fine:

[GridAction]
public ActionResult _Select(int appId) {
    return Json(new GridModel<UnitVM> { Data = GetUnits(appId) });
}

Also, my client side validation is not working on my grid view popup editors.

Any ideas of what I might have broke during the upgrade?

Update: I uninstalled Ninject.MVC3 and I no longer have the problems.  No idea why and no time to look.
