Bind Drop Down List.

I have bind drop down list but i have face a issue.

Choose Category

@Html.DropDownListFor(model => model.EducationImageCategoryName, Model.categoryMasters, "--Select Category--", new { @class = "form-control", @required = "required" })

@Html.ValidationMessageFor(model => model.EducationImageCategoryName, "", new { @class = "text-danger", @style = "color:red;!important" })

There is no ViewData item of type 'IEnumerable' that has the key EducationImageCategoryName

Hi Saurabh,

Please change in below line, You need to bind your category,
@Html.ValidationMessageFor(model => model.EducationImageCategoryName, new SelectList(YourallCategory,"Value","Text","Select Category"), new { @class = "text-danger", @style = "color:red;!important" })

In your Action method you are not passing model object having the property name as EducationImageCategoryName
public class YourClass
{
   public IEnumrable CategoryMasters { set;get;}
   public int CategoryId { set;get;}
   //Add other properties as needed for the view
  public string EducationalImageCategoryName
}

public ActionResult Index()
{
  var vm= new YourClass();

  vm.CategoryMasters = dbContext.CategoryMasters .Select(x=>new SelectListItem { Value=x.CategoryId.ToString(),
  Text= x.CategoryName }).ToList()
  return View(vm);
}
//view
@model YourClass
@Html.DropDownListFor(f=>f.EducationalImageCategoryName, Model.CategoryMasters ,"Select one")
