I am new to Asp.net MVC and currently I want to pass some parameter (selected dates) to the controller when user click the action link button, below is the action link and date picker field code,

```
   <div class="panel panel-default">
    <div class="panel-heading">
        <h3 class="panel-title">
            Manage Outward - Completed</h3>
    </div>
    <div class="panel-body">
        @Html.CreateJQGrid(Model.GridCompletedOWData)
        <br />
        <div class="icon-list">
            @Html.ActionLink("Download Completed Transactions", "ExportToExcelOutwardCompleted", "InwardOutward", new { enctype = "multipart/form-data", model = @Model, FromDate = @Model.DownloadOutwardFromDate.ToString(), ToDate = Model.DownloadOutwardFromDate.ToString() }, new { @id = "DownloadAccount", @class = "linkTxt" })
        </div>
    </div>
       <div class="col-md-3">
                <label for="" class="control-label">
                    Download From Date
                </label>
                @Html.EditorFor(model => model.DownloadOutwardFromDate, new { @class = "form-control" }).DisableIf(() => Model.IsReadOnly == true)
                @Html.HiddenFor(model => model.DownloadOutwardFromDate)
        </div>
        <div class="col-md-3">
            <label for="" class="control-label">
                Download To Date
            </label>
            @Html.EditorFor(model => model.DownloadOutwardToDate, new { @class = "form-control" }).DisableIf(() => Model.IsReadOnly == true)
            @Html.HiddenFor(model => model.DownloadOutwardToDate)
        </div>
        <br />
</div>

```

And my controller,

```
  public ActionResult ExportToExcelOutwardCompleted(CompletedIWOWDetailsModel model, string FromDate, string ToDate)
    {

        var employeeBranch = employeeBranchService.FilterBy(x => x.Userseq == LoggedInUser.UserSeqeunce).Select(x => x.Branchseq).ToList();

        var clientDCAList = clientDcaService.All().Where(x => x.Active == "Y").ToList();
        var List = (from p in trnInflowDetailsP.ToList()

                        p.AuthRemarks
                    }).ToList();

        ExcelPackage excel = new ExcelPackage();
        var workSheet = excel.Workbook.Worksheets.Add("Sheet1");
        workSheet.Cells[1, 1].LoadFromCollection(List, true);
        using (var memoryStream = new MemoryStream())
        {
            Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
            Response.AddHeader("content-disposition", "attachment;  filename=" + Constants.Controller.InwardOutward + ".xlsx");
            excel.SaveAs(memoryStream);
            memoryStream.WriteTo(Response.OutputStream);
            Response.Flush();
            Response.End();
        }
        return View();
    }

```

Now I want to pass the selected date (DownloadOutwardFromDate) as a parameter to the ExportToExcelOutwardCompleted method.But whenever I click the actionlink button then the FromDate parameter is null or default date value, not able to get selected value.So please any one give solution
