Question

So I have a ViewBag.Something and this data is randomly generated. In my view, I set this to a label like so @Html.LabelFor(m => m.Something, (string)ViewBag.Something). This works out well but when I submit the form there could be errors and if there are errors, I need this label to remain the same, I don’t want dynamic/random data anymore so I wouldn’t call the controller method that generated this ViewBag. Is there a way to retain this value without having some private variable in my controller? Some nice way that MVC/Razor does it?

Answer 1

In the get, set up a model, set it dynamically and when return view() is being executed, do return view(model). Then in the view, set up a hidden field that can keep on passing the value needed. I chose to go this route because I don’t have to worry about any server code to make this work on a post and I don’t have to worry about any sessions.
