不写预填充值即可查看的模型

Question

I am using the model class as below

public class Question
{
    public long ID { get; set; }
    public int QuestionNo { get; set; }
    public string Title { get; set; }
    public QuestionTypes QuestionType { get; set; }
    public List<Answer> Answers { get; set; }
}

I created a text box in view as below.

@Html.TextBoxFor(Model => Model.ID);

it pre-populate ID with the values provided which is not I want. I want text box should be empty when rendered and during POST value of the text box should be read by ID property. How can I achieve this or there is a problem with my design?

Answer 1

okay,,

if the Question object you're passing to the View is already initialized, then it will have some value in ID property and that will be shown in the view when you do databindings in the view

So before passing the Question object to the view , set the value of ID to null.

in this way , when your Question will go to view, it will have null value and the textboxfor will be empty
