Calling Partial View from Home/Index problem - asp.net-mvc

Question

I am creating a web page that displays 3 different kind of followers (Red, Blue, Yellow) and a Filter form that users can use to filter.
For instance, if the customer selects a Red option from the dropdown list, I wanna show them only the red followers.
I am creating the select part for now, but I am getting an error which reads like this.
The controller for path '/' was not found or does not implement IController.
This is the
AND this is the FilterController:
public class HomeController : Controller
{
private asp6Entities db = new asp6Entities();
public ActionResult Index()
{
var allFlowers = db.FLOWERs.ToList();
List<FLOWER> result = new List<FLOWER>();
foreach (var flower in allFlowers)
{
FLOWER model = new FLOWER();
model = flower;
result.Add(model);
}
return View(result);
}
public ActionResult About()
{
ViewBag.Message = "Our History";
return View();
}
public ActionResult Contact()
{
ViewBag.Message = "Main Store and Distribution Center.";
return View();
}
[HttpPost]
public ActionResult Index(FilterModel fromColorFilter)
{
string SelectedColor = (fromColorFilter.ColorSelected);
var allFlowers = db.FLOWERs.ToList();
List<FLOWER> result = new List<FLOWER>();
foreach (var flower in allFlowers)
{
if (flower.COLOR.COLOR_NAME == SelectedColor)
{
FLOWER model = new FLOWER();
model = flower;
result.Add(model);
}
}
return View(result);
}
}
THis is the Filter Controller:
public class FilterController : Controller
{
// GET: FilterModel
private asp6Entities db = new asp6Entities();
public ActionResult Index()
{
FilterModel model = new FilterModel();
var color = db.COLORs.ToList().Select(s => new SelectListItem
{
Text = s.COLOR_NAME,
Value = s.COLOR_ID.ToString()
});
return PartialView("~/Views/Shared/_FilterForm.cshtml", new FilterModel { AllColorOptions = color});
}
}
And This is the FilterMethod :
public class FilterModel
{
//declaring the colors selection
public string ColorSelected { get; set; }
//Creating the Size selection
public string SizeSelected { get; set; }
//Creating the starting price selection
public int StartingPriceSelection { get; set; }
//Creating Ends price Selection
public int EndingPriceSelection { get; set; }
//creating IEnumerable of all color options
public IEnumerable<SelectListItem> AllColorOptions { get; set; }
//creating IEnumerable of all Size Options
public IEnumerable<SelectListItem> AllSizeOptions { get; set; }
//creating IEnumerable of Starting Price Options
public IEnumerable<SelectListItem> AllStartingPriceOptions { get; set; }
//creating IEnumerable of Ending Price Options
public IEnumerable<SelectListItem> AllEndingPriceOptions { get; set; }
}
This is the Home Index:
In this Home Index
#Html.Action("Index","FilterForm");

Answer 1

yes this is the best solution
#Html.Action("Index","Filter");

Answer 2

You should change the razor call to this
#Html.Action("Index","Filter");
Your controller is FilterController, therefore, you should use "Filter" as the second parameter, not "FilterForm"
