Ok, this is a really newbie question but I am stumped. I am trying to use a ViewModel to get my data from an entity object and populate the telerik mvc grid.
At this point I am a bit confused and need your help.
I understand the error message but I am not sure how I need to fix this since I am really new to MVC.
----ERROR----
Error 1 Cannot implicitly convert type 'System.Linq.IQueryable' to 'System.Linq.IQueryable'. An explicit conversion exists (are you missing a cast?) ProjectRepository.cs 23 20 MvcMyAPP
I have this viewmodel:
--VIEWMODEL--
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.UI.WebControls;
namespace mvcMyModel.ViewModels
{
public class ProjectViewModel
{
public IQueryable<mvcMyAPP.Models.ProjectRepository> ProjectList
开发者_开发问答 {
get;
set;
}
}
}
--CONTROLLER--
namespace MvcMyAPP.Controllers
{
public class HomeController : Controller
{
// GET: /Home/
ProjectRepository Repository = new ProjectRepository();
public ActionResult Index()
{
ProjectViewModel objProjectViewModel = new ProjectViewModel();
objProjectViewModel.ProjectList = Repository.GetProjects();
return View(objProjectViewModel);
return View();
}
}
}
----REPOSITORY (MODEL)-----
namespace mvcMyAPP.Models
{
public class ProjectRepository
{
mvcMyAPP.Models.MYEntities MYDB = new MYEntities();
//Fetching data from table
public IQueryable<mvcMyAPP.ViewModels.ProjectViewModel> GetProjects()
{
var vProjects = (from tblProjects in MYDB.Projects
select tblProjects);
return vProjects;
}
}
---GRID---
@{Html.Telerik().Grid(Model.ProjectList)
.Name(
"Grid")
.Pageable()
.Sortable()
.Filterable()
.Groupable()
.Render();
}
You don't need the second return View() in the controller, but that isn't causing any problems.
You might try putting a cast on the return variable from your repository so it is returning the type specified in return:
// return vProjects;
// cast the return variable to return type
return (IQueryable<mvcMyAPP.ViewModels.ProjectViewModel>)vProjects;
I highly recommend Microsoft site for learning MVC, they have a great starting point for learning MVC.
