Getting null value in user control mvc

I am trying to add user control for textbox having calender

My View

  @Html.Partial("~/Views/Shared/EditorTemplates/DateTime.ascx", "FromDate");

My User Control

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<String>" %>

<%= Html.TextBox(ViewData.ModelMetadata.PropertyName, new { @class="datepicker"} )%>

<script type="text/javascript">
$(document).ready(function () {
    $('.datepicker').datepicker({
        changeMonth: true,
        changeYear: true,
        dateFormat: 'mm-dd-yy',
        showButtonPanel: true,
        gotoCurrent: true
    });
});

My Controller

[HttpGet]
    public ActionResult SetTask()
    {
        SetTask model = new SetTask();

        var data = (from d in edc.ProjectTBs
                    select d).ToList();


        model.ProjectList = new SelectList(data, "ProjectID", "ProjectName").ToList();
        model.ProjectList.Insert(0, new SelectListItem { Text = "--Select--", Value = "0" });

       // ModelState.Clear();

        return View(model);
    }

Error Message

Please help me for getting value passed from view to user control.

I want to use multiple time on same page of this user control. If there is any other way to like this functionality also helpful.

Instead of Partial View use EditorFor.

Call it like this: <%= Html.EditorFor(m => m.PropertyName) %>

Use this sample if you want in proper way.

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<DateTime?>" %>


 <%= Html.TextBox("", (Model.HasValue ? Model.Value.ToString("dd-MM-yyyy") : string.Empty), new { @class = "datepicker" }) %>


<script type="text/javascript">
    $(document).ready(function() {
        $('.datepicker').datepicker({
    changeMonth: true,
    changeYear: true,
    dateFormat: 'mm-dd-yy',
    showButtonPanel: true,
    gotoCurrent: true
});
    });
</script>
