ServerBinding versus AjaxBinding

[Nate]

This works with server binding but when I change to AjaxBinding I get this error. Anyone know why this does not work in AjaxBinding?

error.Cannot use a lambda expression as an argument to a dynamically dispatched operation without first casting it to a delegate or expression tree type

Code:

 

 

//Used for the Ajax binding

 

[

 

GridAction]

 

 

 

 

public ActionResult _AjaxBinding()

 

 

{

 

 

 

ProjectViewModel objProjectViewModel = new ProjectViewModel();

 

 

objProjectViewModel.ProjectList = Repository.GetProjects();

 

　

 

 

 

return View(new GridModel<MvcMyAPP.T_Project>(objProjectViewModel.ProjectList));

 

 

}

---GRID-----

 

 

@{Html.Telerik().Grid(Model)

 

.Name(

 

 

"Grid")

 

 

 

 

 

 

 

//.Editable(editing=> editing.Mode(GridEditMode.PopUp)

 

 

 

 

 

 

 

.ToolBar(t => t.Insert().ButtonType(

 

 

GridButtonType.Image))

 

 

.DataKeys( keys=>keys.Add(c=>c.ProjectId))

 

.DataBinding(dataBinding => dataBinding.Ajax().Select(

 

 

"_AjaxBinding", "Home")

c.Bound(o=>o.Title);

 

c.Bound(o => o.Description);

 

c.Bound(o => o.ProjectStatus);

c.Bound(o => o.CreatedDate);

 

c.Command(commands =>

 

{ commands.Edit().ButtonType(

commands.Delete().ButtonType(

 

 

GridButtonType.Image); }).Width(200);

 

 

}
