我如何使日期字段@ Html.EditorFor接收来自ViewBag的日期

Question

How do I make the date field @Html.EditorFor receive date coming from a ViewBag.

Controller

var searchDateBD = db.Sequence.ToList().Select(l => l.DateFlow).Max();
ViewBag.date = searchDateBD;

View

@Html.EditorFor(model => model.Sequence.DateFlow, 
                         ViewBag.date, 
                         new { htmlAttributes = new { @class = "form-control input-lg" } })

In this way above developed by me is not correct.

How to do so that the field receives the date coming from the viewbag of the controller

Answer 1

You can overwrite the value using attribute @Value :

htmlAttributes = new { @class = "form-control input-lg", @Value = ViewBag.date }

Note that @Value is written with an uppercase letter V .

Answer 2

You don't need ViewBag here. You can set the model property in the controller action and pass the model object to view back in the line returning View like:

model.Sequence.DateFlow = db.Sequence.Select(l => l.DateFlow).Max();

return View(model);

You also do not need to materialize the result by calling ToList() and leave the Max item to be calculates on the database server.

and in your view it would be like:

@Html.EditorFor(model => model.Sequence.DateFlow, 
                         new { htmlAttributes = new { @class = "form-control input-lg" } })
