Assign DateTime format as data annotations?

Question

I have this attribute in my view model:

[DataType(DataType.DateTime)] public DateTime? StartDate { get; set; } 

If I want to display a date or fill in a date text field, I have the following data:

 <%: Model.StartDate %> <%: Html.TextBoxFor(m => m.StartDate) %> 

Whenever a date is displayed, it is displayed as follows: 01/01/2011 12:00:00 AM

But I would like to show only 01/01/2011

Is there a way to apply a display format with data annotations? I do not want every time I show the date, add code to format it.

Answer 1

Try tagging it:

 [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")] 

Answer 2

Have you tried this?

 [DataType(DataType.Date)] 

Answer 3

In mvc 4, you can easily do this, as after using TextBoxFor ..

 @Html.TextBoxFor(m => m.StartDate, "{0:MM/dd/yyyy}", new { @class = "form-control default-date-picker" }) 

This way you do not need to use data annotation in the model or view model class

Answer 4

If your data field is already a DateTime data type, you do not need to use [DataType(DataType.Date)] for annotation; just use:

 [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")] 

in jQuery, use datepicker for your calendar

  $(document).ready(function () { $('#StartDate').datepicker(); }); 

on your HTML, use EditorFor helper:

  @Html.EditorFor(model => model.StartDate) 

Answer 5

Apply DataAnnotation as:

 [DisplayFormat(DataFormatString = "{0:MMM dd, yyyy}")] 

Answer 6

Use this, but this is the complete solution:

 [DataType(DataType.Date)] [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")] 

Answer 7

Use EditorFor instead of TextBoxFor

Answer 8

After comments

  // [DataType(DataType.DateTime)] 

Use the data annotation attribute:

 [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]

Answer 9

set your property using the code below during model creation. I think your problem will be solved. And the time is not displayed in the database. You do not need to add any annotations.

 private DateTime? dob; public DateTime? DOB { get { if (dob != null) { return dob.Value.Date; } else { return null; } } set { dob = value; } } 

Answer 10

It suits me

 [DataType(DataType.DateTime)] [DisplayFormat(DataFormatString = "{0:dd-mm-yyyy}", ApplyFormatInEditMode = true)]
