Passing value from Controller to View in MVC

Question

I have a view that was generated using data scaffolding. The view has a textfield:

Create View:

Answer 1

You could do this by using the ViewBag to store GroupId as you currently are, but as your view is using a model, it may be better to go that way instead.

So you would have:

Model:

public class GroupModel
{
    public int GroupId { get; set; }
}

Controller:

public ActionResult Create(int id)
{
    var model = new GroupModel();
    model.GroupId = id

    return View(model);
}

At the top of your view, you would then reference your model:

@model GroupModel

You can then access the model in the view using code like model.GroupId as per the scaffolding has done.
