MVC 3 - Change Html.TextBox to Html.TextBoxFor

I am using html.textbox for 2 of my datetime field because I need to format them in a specific format but i don't know how to do it by html.textboxfor. However, I realise i need to have the textboxfor for the validation in my model class to work:

  [Required(ErrorMessage = "Storage Date is required")]
  [DataType(DataType.DateTime, ErrorMessage = "Please input a valid date")]
  public DateTime StorageDate { get; set; }

Any idea how can I change my Html.Textbox below into Html.TextBoxFor with the same setting??

  @Html.TextBox("expirydate", String.Format("{0:ddd, d MMM yyyy}", DateTime.Now), new { id = "expirydate" })
    @Html.ValidationMessageFor(model => model.ExpiryDate)

Appreciate any help... Thanks...

You don't really need to use TextBoxFor() for validation to work. If your TextBox has the same id as a field in the model, the model binder will pick it up. If you're talking about to get the unobtrusive validation features, you can always manually add the data-* attributes to your TextBox.

However, in this case it sounds like what you really want is a custom editor, using EditorFor(). It's a bit more work, but it will allow you to actually enforce the date/time formatting by giving the user something like a date/time picker control. The basic idea is:

  • Create a partial view called DateTime.cshtml that is bound to model of type Nullable<DateTime>, and put it into the Shared/EditorTemplates view folder.
  • Use jQuery and jQueryUI to put an HTML textbox that is styled as a date/time picker into the partial view.
  • Decorate the property on your model with the [DataType(DataType.DateTime)] attribute
  • Use Html.EditorFor(model => model.WhateverProperty)

Fortunately, date/time pickers are probably the most popular custom MVC3 editor, so there are plenty of examples to pick from; the code from this question works fine, just make sure to note the suggestion in the answer and replace this line in the partial view:

@inherits System.Web.Mvc.WebViewPage<System.DateTime>

with this:

@model System.DateTime?
