问题

How can I set default value of input OpenDate is date and time of server.

<div class="form-group">
   <label asp-for="OpenDate" class="control-label">Ngày đăng ký</label>
   <input asp-for="OpenDate" class="form-control" />
   <span asp-validation-for="OpenDate" class="text-danger"></span>
</div>

In your model:
[BindNever]
public System.DateTime OpenDate { get; set; }

In your Controller (where you are posting the form)
yourModel.OpenDate = DateTime.Now;

In your View:
You can exclude the code that you have posted, because it will not be needed.

Note: I used "BindNever" because you can exclude this property from the model binding. It is a data that the system will get for you.
