How to bind dropdown list in edit page use of for loop in asp.net mvc

Question

I was writing different type of code from Google but it is not display correct value in the dropdown. It shows the correct value in the textbox but not selected value in the dropdown.

Model

public Int64 EvaluationInfoID { get; set; }

public Int64 EvalCategoryID { get; set; }

public string EvalCategoryName { get; set; }

public string EvalCategoryDesc { get; set; }

public Int64 UserID { get; set; }

public DateTime? EvaluationDate { get; set; }

public int EvalTypeID { get; set; }

Controller

var models = new List<EvaluationInfoViewModel>();
ViewBag.GridState = this.GridRouteValues();

string serachCriteria = string.Format("created_by={0} and to_date(to_char(evaldate,'MM/DD/YYYY'),'MM/DD/YYYY')={1} ", Convert.ToInt32(Session["UserID"]), "to_date('" + evaldate.ToShortDateString() + "','MM/DD/YYYY')");

PODService.EvaluationInfo[] getData = service.GetEvaluationInfoBySearchCriteria(serachCriteria);

PODService.EvaluationCategory[] evalcat = service.GetEvalCategoryBySearchCriteria(" EC.Eval_ID= 1");//150811VP: For Self Evaluation Eval_ID=1
PODService.EvaluationType[] evalTypes = service.GetEvaluationTypeList();
ViewData["EVALTYPE"] = new SelectList(evalTypes, "EvaluationType_ID", "EvaluationType_Name");



for (var i = 0; i < getData.Length; i++)
{
    models.Add(new EvaluationInfoViewModel());
}

for (var i = 0; i < models.Count; i++)
{
    string serachCriteria1 = string.Format("created_by={0} and to_date(to_char(evaldate,'MM/DD/YYYY'),'MM/DD/YYYY')={1} ", Convert.ToInt32(Session["UserID"]), "to_date('" + evaldate.ToShortDateString() + "','MM/DD/YYYY')");
    models[i].EvalCategoryID = getData[i].EvalCategory_ID;
    models[i].EvalCategoryName = getData[i].EvalCategoryName;
    //models[i].EvalCategoryDesc = getData[i].Eval_CategoryDescription;
    models[i].UserID = Convert.ToInt64(Session["UserID"]);

    models[i].EvaluationDate = getData[i].EvaluationDate;
    models[i].EvalTypeID = getData[i].EvalTypeID;

    ViewData["EVALTYPEInfo"] = new SelectList(evalTypes, "EvaluationType_ID", "EvaluationType_Name", models[i].EvalTypeID);

View

@model  List<PODWeb.Models.EvaluationInfoViewModel>
@{
    Layout = null;

}
@using (Html.BeginForm("EditEvaluationInfo", "EvaluationInfo", FormMethod.Post))
{  
    <table border="1px" style="margin-left: 122px">
        <tr>
            <td>
                <table>
                    @for (var i = 0; i < Model.Count(); i++)
                    {
                        @Html.HiddenFor(m=>m[i].UserID)
                        @Html.HiddenFor(m=>m[i].EvaluationDate)
                        @Html.HiddenFor(m =>m[i].EvalTypeID)
                        <tr>
                            <td>
                                @Model[i].EvalCategoryName
                            @Html.EditorFor(m =>m[i].EvalTypeID)
                            </td>
                            <td>

                              @*@Html.DropDownListFor(m => m[i].EvalTypeID, ViewData["EVALTYPEInfo"] as IEnumerable<SelectListItem>, "Select Rating", new { @style = "width:200px" })*@


                            </td>
                        </tr>

                        <tr>
                            <td>
                                @Model[i].EvalCategoryDesc
                                @Html.HiddenFor(m => m[i].EvalCategoryID)
                            </td>
                            <td>

                            </td>
                        </tr>
                        <tr>
                            <td colspan="2">
                                <hr />
                            </td>
                        </tr>


                    }
                    <tr>
                        <td>
                            <input type="submit" name="Save" value="Save" class="t-button" style="margin-left: 471px" />
                        </td>
                    </tr>
                </table>
            </td>
        </tr>

    </table>
}

You have the code for the dropdown list commented out:

@*@Html.DropDownListFor(m => m[i].EvalTypeID, 
  ViewData["EVALTYPEInfo"] as IEnumerable<SelectListItem>, 
      "Select Rating", new { @style = "width:200px" })*@

You need to remove the outer @* and *@

@Html.DropDownListFor(m => m[i].EvalTypeID, 
   ViewData["EVALTYPEInfo"] as IEnumerable<SelectListItem>, 
     "Select Rating", new { @style = "width:200px" })

Also delete the @Html.EditorFor(m =>m[i].EvalTypeID) from your code.
