Hi PravinKumar,

You are getting the below-mentioned error on the posting the form data.

There is no ViewData item of type 'IEnumerable' that has the key 'JobCodeType'.
In order to resolve that issue, you need to rebind the DropDownlist (i.e. @Html.DropDownList("JobCodeType")), so your post method will be changed to something like below: (Do changes as per your need, I am only setting the viewData again)

public ActionResult ShowDDL(FormCollection obj)

{

  string str = obj["JobCodeType"];

ViewBag.D = obj["JobCodeType"];

List items = new List();

items.Add(new SelectListItem { Text = "Community", Value = "0" });

items.Add(new SelectListItem { Text = "In-House", Value = "1" });

items.Add(new SelectListItem { Text = "Vacation", Value = "2" });

items.Add(new SelectListItem { Text = "Sick", Value = "3" });

items.Add(new SelectListItem { Text = "Absent", Value = "4" });

items.Add(new SelectListItem { Text = "Not Scheduled", Value = "5" });

    if (!string.IsNullOrEmpty(str))

{

        //Selecting the selected value during the Post event

items.Where(x => x.Value == str).FirstOrDefault(s => s.Selected = true);

}

ViewData["JobCodeType"] = items;

    return View("Index");

}

Hope this will help you.

@Html.DropDownList("JobCodeType",

new SelectList((IEnumerable)ViewData["JobCodeType"], "Value", "Text"))

I checked at my end by copy pasting your code in new controller and creating view from it.
It's working fine.
I suggest, you to check with spelling and case.
