I am a beginner ASP.net coder. I understand that the controller is calling a List and the Model is calling a generic model and that this can be easily fixed be setting the model in the view to
@model IEnumerable<WebApplication2.Models.Strategy>
But I want to be able to call the model in the view so I can call it in my view. Below I posted my code.
Controller:
public ActionResult Index(string group, string prin, string status, string osr, string groupnew, string stratvar, string fltstring, Strategy selg, FormCollection form)
{
if (Session["UserId"] != null)
{
Strategy strat = new Strategy();
int id = Int32.Parse(Session["UserId"].ToString()); // Get the user id from the session
String em = db.UserAccounts.Find(id).Email.ToString(); // Use the id to get the associated email address
EmailList emailListItem = db.EmailLists.First(x => x.Email == em); // Use the email address to get the associated emaillist object which holds the group
string perm = emailListItem.Perm;
if (perm == null)
{
perm = "0";
}
ViewData["perm"] = perm;
// if external
if (!emailListItem.IntExt)
{
// Create a list to hold the Todos which we will end up showing
List<Strategy> list = new List<Strategy>();
// this is a foreach loop, it goes through all the Todos returned from db.Todoes.ToList()
foreach (Strategy s in db.Strategies.ToList())
{
// makes sure that the group of a todo isn't null (empty)
if (!String.IsNullOrEmpty(s.Group))
{
// checks if the group of the user is equal to the group of the post. if so it adds the todo to the list.
if (emailListItem.Group.Equals(s.Group))
{
list.Add(s);
}
}
}
return View(list);
}
else
{
// This is the query building code.
string p = emailListItem.Perm;
string gr = emailListItem.Group;
StringBuilder sb = new StringBuilder();
sb.Append("SELECT * FROM dbo.Strategy WHERE "); //change table name for whatever you need returned
foreach (char c in p.ToCharArray())
{
if (group == null)
{
sb.Append("Perm LIKE '%");
sb.Append(c);
sb.Append("%' OR ");
}
}
sb.Length = sb.Length - 4;
if (selg == null)
{
List<Strategy> list = db.Strategies.SqlQuery(sb.ToString()).ToList(); //change table name
return View(list);
}
else
{
var groups = from g in db.Strategies
select g;
var prins = from pr in db.Strategies
select pr;
var osrs = from o in db.Strategies
select o;
var statuss = from s in db.Strategies
select s;
ViewBag.Groupcmb = (from g in db.Strategies.Include(p) where g.Group != null
select g.Group).Distinct();
ViewBag.Principalcmb = (from pr in db.Strategies.Include(p) where pr.Principal != null
select pr.Principal).Distinct();
ViewBag.OSRcmb = (from o in db.Strategies.Include(p) where o.OSR != null
select o.OSR).Distinct();
ViewBag.Statuscmb = (from s in db.Strategies.Include(p) where s.Status != null
select s.Status).Distinct();
//ViewData["OSR"] = new SelectList(ViewBag.OSRcmb);
ViewBag.osrsel = osr;
//if all filters are null
if (group == null && stratvar == null && prin == null && osr == null && status == null)
{
return View(db.Strategies.ToList());
}
//returns same search filter for group if edit
if (stratvar != null && group == null)
{
group = stratvar;
groups = groups.Where(g => g.Group.Contains(group));
// return View(group.ToList());
};
if (prin != null && group != null && osr != null && status != null)
{
ViewBag.osrsel = osr;
prins = prins.Where(gpr => gpr.Principal.Contains(prin) && gpr.Group.Contains(group) && gpr.OSR.Contains(osr) && gpr.Status.Contains(status));
stratvar = null;
return View(prins.ToList());
}
return View(strat);
}
}
}
else
{
return RedirectToAction("Login", "Account");
