Custom view control for MVC doesn't work?

I have the following custom view control in MVC. However, it doesn't work at all.

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.DateTime?>" %>
<%=Html.TextBox("", (Model.HasValue ? Model.Value.ToShortDateString() : string.Empty), new { @class = "timePicker" }) %>

And this is where I use it from, and how:

    <div class="editor-field">
        @Html.EditorFor(model => model.StartTime)
        @Html.ValidationMessageFor(model => model.StartTime)
    </div>

The model looks like this:

[Bind()]
[Table("DailyReports", Schema = "Actives")]
public class DailyReport
{

    [Key()]
    [Display(AutoGenerateField = false, AutoGenerateFilter = false)]
    public int ID { get; set; }

    [DisplayName("Starttidspunkt")]
    public DateTime? StartTime { get; set; }

    [DisplayName("Sluttidspunkt")]
    public DateTime? EndTime { get; set; }

    [DisplayName("Time-rapporter")]
    public virtual ICollection<HourlyReport> HourlyReports { get; set; }

    public DailyReport()
    {

    }
}

However, a simple textfield just shows up, when in reality, I expect the view user control to show up, since the type is DateTime.

Any suggestions on how to solve this?

I'm assuming that you're correctly placing your template in the EditorTemplates folder, and that you're naming it after the correct type (ie DateTime.aspx)

Beause you're using a nullable type, you need to specify the template name manually.

<%: Html.EditorFor(model => model.StartTime, "NullableDateTimeTemplate" )%>

Or, you can check the model metadata to determine if the type is nullable.

<% if (ViewData.ModelMetadata.IsNullableValueType) { %>
    <%= Html.TextBox("", (Model.HasValue ? Model.Value.ToShortDateString() : string.Empty), 
        new { @class = "timePicker" }) %>   
<% } else { %>
    <%= Html.TextBox("", Model.ToShortDateString(), new { @class = "timePicker" }) %>   
<% } %>
