I am using visual studiio 2015 and i am using its default datetime picker in my MVC5's App. i am facing problem while showing the datetime picker. it is showing only date picker and not time picker. but i need time picker also. here is my code of datetimepicker in model
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = false)]
[Required(ErrorMessage = "Start DateTime is required")]
public Nullable<System.DateTime> start_date_time { get; set; }
while i set DateTime in place of Date No Controller comes only textbox appear.

There is no default datetime picker in MVC5. What the [DataType] attribute does is render the type attribute for the <input> element your generating that will then be used by the browser to render the appropriate HTML5 control if supported. In the case of DataType.Date, it generates <input type="date" ... />
At the current time only recent versions of Chrome support type="date". If you tested this using IE or FireFox, you would only get a standard textbox.
Using [DataType(DataType.DateTime)] generates type="datetime" but this is not currently supported in either Chrome, IE or FireFox, which is why you see only the standard textbox.
Recent versions of Chrome however do support type="datetime-local" which will render a control allowing you to select both a date and a time. There is no [DataType] type which generates this but you can use
@Html.TextBoxFor(m => m.start_date_time, "{0:s}", new { @type = "datetime-local" })
Note "{0:s"} is shorthand for "{0:yyyy-MM-ddTHH:mm:ss}"
You can compare various versions of browsers and which of the HTML5 field types they support using this site.
Due to the current limited support, I recommend you consider using a jquery datetimepicker plugin rather than browsers HTML implementations.
