System.InvalidOperationException: Nullable object must have a value

I am trying to render the following in a MVC view with a nullable DateTime(DateTime?), but I got "System.InvalidOperationException: Nullable object must have a value". When the value is not null, show the time part (13:15:00) of the date time string (01/01/2014 13:15:00). What is happening? Thanks.

   @Html.EditorFor(model => model.Task.Scheduled_Time.Value, "{0:t}")

Remove the .Value.

When using the HTML helper methods you need to tell the helper which property you want to use (and what it's type is).

If you say

model => model.Task.Scheduled_Time

You're saying: "Get the model and create an editor for whatever Scheduled_Time is."

If you say

model => model.Task_Scheduled_Time.Value

You're saying: "Get the model and create an editor for the property of the value of Scheduled_Time."

If Scheduled_Time isn't set (that is: it's null) then .Value is nothing and so the property you're trying to select isn't really accessible.
