Question

Please help me on this.

I have written a code for getting the first record from the database using LINQ

My Homecontroler

[CustomHandleError]
    public class HomeController : Controller
    {
        Domain domain;
        public HomeController()
        {
            domain = new Domain();
        }

        public ActionResult Index()
        {
            HomePageViewModel vm = new HomePageViewModel();
            vm.Page = domain.GetHomePageInfo();

            if (vm.Page != null)
            {
                ViewBag.Title = vm.Page.PageTitle;
                ViewBag.Keywords = vm.Page.PageKeywords;
                ViewBag.Description = vm.Page.PageDesc;
                ViewBag.PageImage = vm.Page.PageTabImage;
                ViewBag.ColorCode = vm.LatestNewsLetter.IssueColorCode;
                ViewBag.emptyItemCount = emptyItemCount;
                return View(vm.Page.PageTemplate, vm);
            }
            return View(vm);
        }
}


DataAccess Method

   #region Front End
        public Page GetHomePageInfo()
        {
            try
            {
                Page pagedata = new Page();

                pagedata = context.Page.Where(x => x.PageIsHomePage == true && x.PageActive==true && x.PageVisible==true).FirstOrDefault();
                return pagedata;
            }
            catch (Exception ex)
            {
                CustomFilters.logerrortextfile.errorlog(ex, "GetHomePageInfo");
