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" }) https://stackoverflow.com/questions/37407811/mvc5-razor-html-dropdownlistfor-set-selected-when-value-is-in-array https://www.completecsharptutorial.com/asp-net-mvc5/html-dropdownlist-and-html-dropdownlistfor-example-in-asp-net-mvc.php

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" )
