create method mvc with dropdownlist from model code example
Example 1: how to use dropdownlist in mvc
BY LOVE
1- Create a simple method to get the dropdown value
public List<SelectListItem> GetCategories()
{
var ResultCategory = objRKMGEntities.Categories.ToList();
List<SelectListItem> listCategories = new List<SelectListItem>();
foreach (var items in ResultCategory)
{
listCategories.Add(new SelectListItem() { Text = items.Category_Name, Value = items.Category_Id.ToString() });
}
return listCategories;
}
2- Call the GetCategories() in action method and store the data in viewbag.
public ActionResult SubCategory()
{
ViewBag.Categories = GetCategories();
return View();
}
3- Use the viewbag object in the dropdownlist of the view
@Html.DropDownList("CategoryId", ViewBag.Categories as List<SelectListItem>, "Select Category")
Example 2: razor dropdownlistfor
@using MyMVCApp.Models
@model Student
@Html.DropDownListFor(m => m.StudentGender,
new SelectList(Enum.GetValues(typeof(Gender))),
"Select Gender")
